       FIG.  1 A  illustrates an example of a conventional shelter  100  with sidewalls  101  and side skirts  106  attached to the legs  104 . The sidewalls  101  and side skirts  106  may be formed of a fabric material such as a polyester fabric. As previously discussed, in conventional systems, the sidewalls  101  and side skirts  106  may attach directly to the legs  104  or perimeter truss via a connection, such as a fastener attached to a strap. The connections are neither secure nor taut. Therefore, the sidewalls  101  and side skirts  106  are prone to sagging or disconnecting from the legs  104 . Additionally, or alternatively, banners, flags, and/or other types of dressings may be mounted to the legs and/or frame. As an example, half walls  110  may also be mounted to the legs  104 .  FIG.  1 B  illustrates another example of a booth structure  150  with flags  180  and banners  190  may be mounted to the legs  154 . 
     As shown in  FIGS.  1 A and  1 B , the sidewalls  101 , side skirts  106 , flags  180 , and banners  190  are visible from the exterior of the shelter  100 . The sidewalls  101 , side skirts  106 , flags  180 , and banners  190  may have information printed on both sides. Still, there is unused space on the interior of a shelter&#39;s dome (e.g., ceiling). Still, the space on the interior of the shelter&#39;s dome may also be used to provide information (e.g., advertisements). Conventional fastening systems do not provide a system for attaching structures, such as flags and banners to an interior of the shelter. 
     It is desirable to provide a system to improve a customer&#39;s ability to attach various structures to a shelter. Aspects of the present disclosure are directed to a multi-point attachment system that provides multiple points in a shelter for securely fastening a structure, such as a flag, banner, side skirt, tent, etc., to the shelter&#39;s frame. According to aspects of the present disclosure, the multi-point attachment system provides a solution for a customer to attach different structures to the interior and/or exterior of the frame. 
     In one configuration, the multi-point attachment system provides attachment points at a center of a shelter as well as corners of the shelter. Of course, aspects of the present disclosure are not limited to providing attachment points at the center and all corners, as various configurations are contemplated based on a customer&#39;s need. 
     Some shelters may have a roof structure that is elevated with a telescoping peak beam. The peak beam may be connected to a bracket (e.g., center bracket) with multiple sockets. The sockets may receive one end of the peak beam as well as ends of truss links. In one configuration, one or more attachment points are provided at the center bracket. 
       FIG.  2    illustrates an example of a center bracket  200  according to aspects of the present disclosure. As shown in  FIG.  2   , an end of a peak beam  220  is coupled to a center socket  202  of the center bracket  200 . The end of the peak beam  220  may be secured to the center socket  202  via a bolt  222  or other type of fastener. The center socket  202  may be a square shaped socket for receiving an end of the peak beam  220 . Of course, the center socket  202  may have other shapes, such as a circle or other parallelogram, based on a shape of the peak beam  220 . 
     Additionally, the center bracket  200  includes multiple side sockets  206  extending from the body of the center bracket  200 . In one configuration, each socket is at substantially right angles from an adjacent socket  206 .  FIG.  2    illustrates the center bracket  200  with four sockets  206 . Aspects of the present disclosure are not limited to the center bracket  200  with four sockets  206  as more or fewer sockets  206  are contemplated. 
     Each socket  206  is coupled to a truss link  204  via a bolt  222  or other type of fastener. The truss links  204  may pivot within the respective sockets  206 . In one configuration, to allow a truss link  204  to pivot when coupled to a socket  206 , the sockets  206  include three sides (e.g., two arms  216  and a base  218 ). Furthermore, as shown in  FIG.  2   , a handle  208  is attached to each socket  206 . In one configuration, the handle  208  is u-shaped and is attached to an outer side of the base  218 . The inner side of the base  218  refers to a side that is adjacent to a truss link  204 . Aspects of the present disclosure are not limited to the handles  208  having a u-shape and are contemplated for other designs that allow for a fastener  210 , or other apparatus, to attach to the handle. Aspects of the present disclosure are not limited to the handles  208  being attached to the outer side of the base  218  and are contemplated for the handles  208  being attached to other portions of the center bracket  200 . 
     As shown in  FIG.  2   , the fastener  210  is attached to the handle  208 . As an example, the fastener  210  may be a hook, clasp, clip, or other type of structure to be coupled with the handle  208  of the socket  206 . An opening  214  of the fastener  210  may receive a connector from a dressing, such as a wall, sidewall, skirt, flag, and/or banner. That is, the opening  214  is specified to receive a strap or material connected to a dressing, such as a wall, sidewall, skirt, flag, and/or banner. 
       FIG.  3    illustrates an example of a fastener  300  according to aspects of the present disclosure. In one configuration, the fastener  300  is provided for attaching a dressing or structure to an attachment point, such as a handle of a bracket. As shown in  FIG.  3   , the fastener  300  includes a hook portion  302  that curves at a top of the fastener  300 . A portion of the fastener  300  extends outward at the nose of the hook portion  302  to form a v-shaped end  304  for the fastener  300 . As previously discussed, the fastener  300  is adapted to clip to a handle of a bracket. The v-shaped end  304  improves the retainment of the fastener  300  with a handle (e.g., attachment) of a multi-point attachment system. 
     Furthermore, as shown in  FIG.  3   , in one configuration, a strap  306  is extended through the opening  308  of the fastener  300 . The opening  308  may be defined in a rectangular shaped end  310  of the fastener  300 . Of course, aspects of the present disclosure are not limited to the fastener  300  having a rectangular shaped end  310  as other shapes are contemplated. The strap  306  may be sewn (e.g., connected) to a material of a dressing, such as a sidewall or skirt. Aspects of the present disclosure are also contemplated for the strap  306  to be connected to material of other structures, such as a tent, a flag, an inner wall extending along the roof of the canopy, or any other type of dressing (e.g., structure/fabric/material). In one configuration, the length of the strap  306  is adjustable. 
     As previously discussed, a center bracket may include attachment points (e.g., handles) for a multi-point attachment center. In one configuration, attachment points are defined on leg brackets of a shelter. The attachment points on the leg brackets may be provided alternate to or in addition to the attachment points of the center bracket.  FIGS.  4 A and  4 B  illustrate examples of different views of a leg bracket  400  according to aspects of the present disclosure.  FIG.  4 A  illustrates a first view (e.g., front view) of the leg bracket  400  and  FIG.  4 B  illustrates a second view (e.g., back view) of the leg bracket  400 . The second view is opposite of the first view. As shown in  FIGS.  4 A and  4 B , the leg bracket  400  is connected to a leg  402  of the collapsible frame. That is, a socket  420  of the leg bracket  400  receives an end of the leg  402 . The leg  402  may be attached to the socket  420  via a bolt or other attachment (not shown). 
     The leg bracket  400  includes multiple sockets  404  extending outward from a body  412  of the leg bracket  400 . Each socket  404  may be at substantially right angle from an adjacent socket  404 . Aspects of the present disclosure are not limited to two sockets  404  as shown in  FIGS.  4 A and  4 B ; the leg bracket  400  may have one or more sockets  404 . For example, in one configuration, the leg bracket  400  includes only one socket  404  extending outward from a body  412  of the leg bracket  400 . 
     An end of a link member  408  is received in each socket  404  of the leg bracket  400 . The end of the link member  408  may be pivotally connected to the socket  404 . Specifically, the end of the link member  408  may be attached to the socket via a bolt  424  or other attachment. The socket  404  of the leg bracket  400  includes two arms  416 . As a roof and a floor are not defined for each socket  404  of the leg bracket  400 , the link member  408  may pivot in an up or down direction. 
     In one configuration, a handle  410  (e.g., attachment point) is defined below each socket  404 . A first end of the handle  410  may be attached to a bottom of one arm  416  of the socket  404  and a second end of the handle  410  may be attached to the body  412  of the leg bracket  400 . Each handle  410  may be adaptable to receive a fastener  414 . As previously discussed, the fastener  414  is adapted to be connected to material of a structure via a strap or other type of connector. The leg bracket  400  is not limited to receiving link members and may receive telescoping pole members or other structures of a frame of a shelter. 
       FIG.  5 A  illustrates an example of a frame of a shelter  500  in accordance with aspects of the present disclosure. The shelter  500  may be a modular folding shelter, such as a display booth. As shown in  FIG.  5 A , the frame has four sides  504  and four corners. Each side  504  may be substantially perpendicular to one or more adjacent sides  504 . Of course, aspects of the present disclosure are not limited to a frame with four sides and four corners, as other configurations, such as three sides and three corners, are also contemplated. Additionally, adjacent sides  504  may be connected at an angle that is greater than or less than 90 degrees. The frame may be collapsible. In another configuration, the frame is fixed. 
     In one configuration, legs  508  are provided at each corner to erect the frame. The legs  508  may be telescoping (e.g., extendable). That is, each leg  508  may comprise a telescoping lower section  520  that extends from a hollow upper section  522 . The telescoping lower section  520  may be slidably disposed within hollow upper section  522 . Each telescoping lower section  520  has a foot  540  for engagement with the ground. Additionally, a perimeter truss frame  550  is connected to the legs  508  via brackets  524 ,  526  to stabilize and support the frame of the shelter  500 . The perimeter truss frame  550  may also be referred to as a perimeter truss framework. 
     The perimeter truss frame  550  may include multiple outer truss links  552  and multiple inner truss links  554 . Two outer truss links  552  may form an outer truss link pair. The outer truss links  552  of each outer truss link pair may be pivotally connected to each other at a cross-link joint  536 , such as in a scissor configuration. In one configuration, a first end of each outer truss link  552  is pivotally connected to a leg  508  via either a leg bracket  524  or a sliding bracket  526 . That is, a first end of one outer truss link  552  of each outer truss link pair may be pivotally connected to a socket of the leg bracket  524 . Each socket of the leg bracket  524  may include an attachment point (e.g., handle) for receiving a fastener (see  FIGS.  4 A-B ). The first end of another outer truss link  552  of each outer truss link pair may be pivotally connected to a socket of a sliding bracket  526 , such that one outer truss link  552  of an outer truss link pair is slidably connected to a corresponding leg  508 . A second end of each outer truss link  552  may be connected to a second end of another outer truss link  552  at an outer joint  530 . The outer joint  530  may be a three-way joint. 
     As shown in  FIG.  5 A , two inner truss links  554  may be pivotally connected at a cross-link joint  536  to form an inner truss link pair. Two inner truss links  554  may be pivotally connected, such as in the scissor configuration. In one configuration, a first end of a first inner truss link  554  is pivotally connected to a second end of two outer truss links  552  at an outer joint  530 . A second end of the first inner truss link  554  of each inner truss link pair is pivotally connected to a peak slider  518 . Furthermore, a first end of a second inner truss link  554  of each inner truss link pair is pivotally connected to a second end of two outer truss links  552  at an outer joint  530 . A second end of the second inner truss link  554  of each inner truss link pair is pivotally connected to a socket of the center bracket  528 . Each socket of the center bracket  528  may include an attachment point (e.g., handle) for receiving a fastener (see  FIG.  2   ). 
     The shelter  500  may include a peak beam  532  for supporting a roof structure (not shown), such as a canopy. The peak beam  532  may be attached to a center bracket  528 . The peak slider  518  may also be slidably attached to the peak beam  532 . In one configuration, a peak pole  534  is telescoping (e.g., extendable) from the peak beam  532 . That is, the peak beam  532  may be hollow so that the peak pole  534  may extend upward from the peak beam  532 . The peak pole  534  may be slidably disposed within the peak beam  532 . Additionally, the peak pole  534  may include a top bracket  538  for engaging a roof structure, such as a canopy. 
     The top bracket  538  may also include attachment points. In one configuration, a sail banner may be attached to an attachment point of the top bracket  538  and an attachment point on one or more leg brackets  524 . Additionally, or alternatively, the sail banner may be attached to other components of the shelter. The sail banner may be used to display information on the interior of the shelter  500 . In one configuration, a roof material may be placed on the shelter  500 . In this configuration, the roof structure is placed over the sail banner, such that only the roof structure is visible from the exterior of the shelter  500 , while both the roof structure and the sail banner are visible from the interior of the shelter  500 . 
       FIG.  5 A  illustrates an example of a sliding bracket  526  according to aspects of the present disclosure. As shown in  FIG.  5 A , a leg  508  passes through an opening of the sliding bracket  526 . A pin  502  is used to engage the sliding bracket  526  with an opening in the leg  508  to keep the sliding bracket  526  in a desired position. The sliding bracket  526  includes one or more sockets  542  for engaging an end of a truss link, such as an outer truss link  552 . A truss link may pivot within the socket  542 . In one configuration, the sliding bracket  526  includes one or more attachment points of the multi-point attachment system. 
     Aspects of the present disclosure are not limited to two outer truss link pairs per side. The number of outer truss link pairs, per side, may be less than or greater than two. For example, as shown in  FIG.  5 B , a first side  560  of a shelter  566  may include three outer truss link pairs  564  and a second side  562  may include two outer truss link pairs  564 . In this example, the shelter  566  may include multiple peak beams  568 . The other portions of the frame of the shelter  566  are similar to the frame of the shelter  500  of  FIG.  5 A . For brevity, the elements of the shelter  566  of  FIG.  5 B  that are the same as the elements of the shelter  500  of  FIG.  5 A  will not be discussed in detail.

A first end of each upper peak truss link  652  may be pivotally connected to a leg bracket  602 . The leg bracket  602  may include a handle on each socket (see  FIGS.  4 A- 4 B ). A second end of each upper peak truss link  652  may be pivotally connected to a dome center bracket  656 . Each upper peak truss link  652  may also include a joint  658 , such that a first portion  652   a  and a second portion  652   b  of each upper peak truss link  652  are foldable. A first end of a lower peak truss link  654  may be pivotally connected to the upper peak truss link  652  at a joint  660 . A second end of the lower peak truss link  654  may be pivotally connected to a socket of a sliding bracket  664 . 
     The lower peak truss links  654  may provide support to a corresponding (e.g., adjacent) upper peak truss link  652 . The upper peak truss links  652  and lower peak truss links  654  form a dome for supporting a roof structure (not shown), such as a canopy. The lower peak truss links  654  and the upper peak truss links  652  may be a flexible material. For example, the lower peak truss links  654  and the upper peak truss links  652  may be flexible rods, such as composite fiber rods. The flexibility improves wind resistance. 
     As an example, a tent shelter, such as a cube tent, gazebo, or a structure with a roof, may be erected within the shelter  650 . In one configuration, the tent shelter may have a cube shape and the sides of the tent shelter may be attached to attachment points on the leg brackets  602 . Furthermore, a strap may be attached to the roof of the structure and an attachment point of the dome center bracket  656 . The dome of the shelter  650  may then be covered with a roof fabric. The flexibility of the upper peak truss links  652  as well as the connection between the roof of the tent shelter and the dome of the shelter  650  improves the wind resistance of the structure. Aspects of the present disclosure are not limited to erecting a tent shelter in shelters with flexible peak truss links, as the tent shelter may be erected in any type of shelter with a multi-point attachment system. 
       FIG.  7    illustrates an example of a shelter in a partially collapsed position. As shown in  FIG.  7   , a perimeter truss link assembly  700  having multiple perimeter truss pairs of link members  706  is connected to each leg  702 . Each of the perimeter truss pairs including first link members  708  and second link members  710  that are pivotally connected together, such as in a scissors configuration. The first link member  708  and second link members  710  have inner ends  712  and outer ends  714 . The outer end  714  of each first link member  708  connected to the upper end of one leg  702  via a leg bracket  720 , and the outer end  714  of each second link member  710  being connected to a sliding leg bracket member  716  so as to be slidably connected to the leg  702 . The inner ends  712  may be pivotally connected to each other. Each leg  702  may comprise a hollow upper section  726  and a telescoping lower section  728 , with the lower section slidably disposed within the upper section, with the lower section having a foot section  770  for engagement with the ground. An end  722  of each leg  702  is connected to the leg bracket  720 . 
     As previously discussed, a conventional portable room, such as a tent, may be assembled by erecting fabric using poles, stakes, and/or rope.  FIG.  8    illustrates an example of a conventional portable room  800 . As shown in  FIG.  8   , the portable room  800  includes fabric  802  and poles  808 . Each pole  808  may include multiple interlocking pole pieces. The pole  808  is assembled by interlocking the pole pieces. Of course, the pole  808  may be interlocking or may be one piece. The poles  808  may be flexible to create an arch in the fabric  802 . Furthermore, the poles  808  may be attached to the fabric  802  via tubes in the fabric  802 , or via other attachments. Each end of a pole  808  may be secured to the ground via a stake (not shown). Finally, for added stability, ropes (not shown) may be attached to the fabric  802  and the ground. 
     As is known to those of skill in the art, erecting the conventional portable room  800  via the poles  808  is cumbersome and time consuming. Furthermore, the conventional portable room  800  may have a low profile (e.g., low height). The low profile may reduce instability caused by wind or other elements. Still, the low profile of the portable room  800  reduces an amount of space that is available. 
     To increase an amount of space, the length of the poles  808  may be increased to provide a higher arch for the portable room  800 . The higher arch may increase the amount of space within the portable room  800 . Still, as the arch increases, the wind stability decreases. Additionally, or alternatively, the footprint of the portable room  800  may increase. That is, a perimeter of the fabric  802  may be increased. However, as the footprint increase, the wind stability decreases. 
     In some cases, to increase an amount of space and to also reduce assembly time, conventional portable rooms may be attached to an erectable frame.  FIG.  9 A  illustrates an example of a conventional portable room  900  attached to an erectable frame  902  (e.g., collapsible frame). The frame  902  may include multiple legs  908  and multiple peak links  912 . Each leg  908  is attached to a peak link  912  via a joint  914 . Furthermore, the peak links  912  may be connected to a center bracket  916 . 
     As shown in  FIG.  9 A , walls  904  and a roof  906  of the portable room  900  are attached to the frame  902 . Specifically, each edge of two adjacent walls  904  is attached to a leg  908  of the frame  902 . The edges may be attached to the legs  908  via fasteners  910 . Additionally, the roof  906  is attached to the peak links  912  via fasteners  910 . 
     A center of the roof  906  may be attached to the center bracket  916  via a center fastener  918 . The center fastener  918  may latch onto the center bracket  916 . Alternatively, the center fastener  918  may be tied to a fastener of the center bracket  916 . In this example, the roof  906  extends at an upward angle that is similar to an angle of the peak of the frame  902 . Still, the roof  906  and the angle of the peak may be substantially flat. A canopy (not shown) may be placed over the peak links  912  to provide additional protection from the elements. The peak links  912  of the frame  902  are made of rigid tubes, such as metal or fiberglass. That is, the peak links  912  are not flexible. 
       FIG.  9 B  illustrates another example of a conventional portable room  950  attached to an erectable frame  954  (e.g., collapsible frame). The frame  954  may include multiple legs  958  and multiple peak links  960 . Each leg  958  is attached to a peak link  960  via a joint  962 . Furthermore, the peak links  960  may be connected to a center bracket  964 . 
     As shown in  FIG.  9 B , walls  952  and a roof  970  of the portable room  950  are attached to the frame  954 . Specifically, each edge of two adjacent walls  952  is attached to a leg  958  of the frame  954 . The legs  958  and peak links  960  may pass through tubes  972 . In this example, a center of the roof  970  is not attached to the center bracket  964 . As shown in  FIG.  9 B , the roof  970  extends at an upward angle that is similar to an angle of the peak of the frame  954 . The peak links  960  are made of rigid tubes, such as metal or fiberglass. That is, the peak links  960  are not flexible. 
     Although the portable rooms  900 ,  950  of  FIGS.  9 A- 9 B  may provide additional space in comparison to the portable room  800  of  FIG.  8   , the portable rooms  900 ,  950  may be unstable due to their profile (e.g., height). Additionally, regardless of whether a canopy is placed over the peak, the rigid nature of the peak links  912 ,  960  reduces the wind resistance of the portable rooms  900 ,  950 . Therefore, the portable rooms  900 ,  950  may topple in high winds. 
     Aspects of the present disclosure are directed to a portable room and shelter with improved wind resistance. Furthermore, aspects of the present disclosure reduce assembly time based on the use of various brackets provided on a frame of a shelter. 
     In one configuration, to improve wind resistance, a flexible center strap connects a roof of the portable room to peak links of a frame. The connection between the portable room and the peak links via the flexible center strap provides flexibility to the portable room and the frame, thereby improving wind resistance. 
       FIG.  10 A  illustrates an example of assembling a portable room  1000  according to aspects of the present disclosure. As shown in  FIG.  10 A , at block  1020 , the portable room  1000  is placed within an area defined by a portable shelter  1012 . A frame of the portable shelter includes multiple legs  1002 , perimeter truss links  1004 , and flexible peak links  1006  (See  FIG.  6 B ). A canopy  1008  may be placed over the perimeter truss links  1004  and peak links  1006 . 
     In one configuration, a flexible strap  1010  is attached to a roof of the portable room  1000 . When assembling the portable room  1000 , the flexible strap  1010  may be attached to one or more peak links  1006 . At block  1030 , the flexible strap  1010  is attached to two flexible peak links  1006 . An end of the flexible strap  1010  may split into a first arm  1010 A and a second arm  1010 B. Each arm  1010 A,  1010 B may attach to a different peak link  1006 . The arms  1010 A,  1010 B may also attach to handles (not shown) of a center bracket  1014  (See  FIG.  5 A ). Of course, the flexible strap  1010  may include more than two arms. In another configuration, the flexible strap  1010  is a single piece. Each end of the flexible strap  1010  includes a fastener for attaching to the flexible peak link  1006  or the handle of the center bracket  1014 . 
     By attaching the flexible strap  1010  to the flexible peak links  1006  or the handle of the center bracket  1014 , the wind resistance of the portable room is increased based on the flexibility of the flexible strap  1010  and the flexible peak links  1006 . The flexible peak links  1006  may also attach to rigid peak links (See  FIG.  6 A ). After attaching the flexible strap  1010  to the flexible peak links  1006 , other portions of the portable room  1000  may be attached to the portable shelter  1012 . 
     As shown in  FIG.  10 B , roof straps  1022  may be attached to the flexible peak links  1006 . The portable room  1000  may include multiple roof straps  1022 . For example, the portable room  1000  may include four roof straps  1022 . Each roof strap  1022  may be defined on an edge of a roof and a sidewall of the portable room  1000 . 
     Additionally, as shown in  FIG.  10 C , upper edge straps  1026  may be attached to the perimeter truss links  1004 . One or more upper edge straps  1026  may be attached to each upper corner of the portable room  1000 . The upper corner may be defined as an area where two adjacent sidewalls attach to the roof. For example, the portable room  1000  may include upper edge straps  1026  at each upper corner. The upper edge straps  1026  may attach to the perimeter truss links  1004  via fasteners  1028 . The upper edge straps  1026  may also attach to handles (not shown) of leg brackets (See  FIG.  5 A ). 
     Furthermore, as shown in  FIG.  10 D , multiple edge straps  1034  may be attached to each leg  1002 . The edge straps  1034  may wrap around each leg  1002 . The edge straps  1034  may use hook fasteners, hook and loop fasteners (e.g., VELCRO™), or another type of fastener to attach to each leg  1002 . The edge straps  1034  may be defined on an edge where two adjacent sidewalls  1032  meet. 
     As shown in  FIG.  10 D , the sidewalls  1032  may be substantially opaque. In one configuration, as shown in  FIG.  10 E , a mesh-screen  1050  may be defined on one or more sidewalls  1032  of a portable room  1000 . For example, as shown in  FIG.  10 E , the mesh-screen  1050  is defined on each sidewall  1032 . One or more of the mesh-screens  1050  may be configured to open and close. For example, a zipper may be provided on the mesh-screen  1050  to open and close the mesh-screen  1050  to allow access to an inner area of the portable room  1000 . 
     In another configuration, the sidewalls  1032  may be airtight. That is, the sidewalls  1032  may provide a sealed enclosure such that elements within the portable room  1000  do not venture into an exterior environment of the portable room  1000 . The airtight portable room  1000  may be used as a forensics lab (e.g., crime scene lab). The airtight portable room  1000  may also be used as a decontamination chamber. In this example, an input hose may provide water to a shower fixture within the interior of the portable room  1000  and a drainage hose may drain water from the interior of the portable room  1000 . The portable room  1000  may have many other uses. A size of the portable room  1000  is not limited to the sizes discloses herein. The portable room  1000  may be larger or smaller. 
     As discussed, it may be desirable to integrate compartments (e.g., pockets) into the ceiling of a portable room. In one configuration, to improve air quality, the pockets receive filters. Specifically, the filters may be used for dust containment and improved air quality. The air quality refers to the air quality within the portable room or the quality of the air surrounding the portable room. 
       FIG.  11    illustrates an example of a portable room  1100  with an air filtration system according to aspects of the present disclosure. As shown in  FIG.  11   , the air filtration system may include a vent  1102  and a ventilation fan  1120 . The vent  1102  may be integrated with one or more walls  1116  of the portable room  1100 . The vent  1102  may be used to remove air from the portable room  1100 . The vent  1102  may have a cylindrical shape and may extend outwards from a wall  1116 . 
     The ventilation fan  1120  may directly attach to the vent  1102 . Alternatively, the ventilation fan  1120  may attach to the vent  1102  via an air duct  1122 . That is, one end of the air duct  1122  attaches to the vent  1102  and another end of the air duct  1122  attaches to the ventilation fan  1120 . The vent  1102  or air duct  1122  may wrap around an opening of the ventilation fan  1120 . The ventilation fan  1120  may be used to suck air out of the portable room  1100  or blow air into the portable room  1100 . The ventilation fan  1120  is not limited to the type of ventilation fan  1120  shown in  FIG.  11   , other types of ventilation fans  1120  are contemplated. 
     In another configuration, the vent  1102  is attached to an air conditioner  1130 . The air conditioner  1130  may be used to adjust a temperature within the portable room  1100 . For example, the air conditioner  1130  may lower the temperature within the portable room  1100 . In yet another configuration, the vent  1102  may be attached to a heater to increase the temperature within the portable room  1100 . The heater may be the same device as the air conditioner  1130 . The heater and/or air conditioner  1130  may attach to the vent  1102  via the air duct  1122 . 
     As shown in  FIG.  11   , multiple pockets  1104  may be integrated with a roof  1106  of the portable room  1100 . Aspects of the present disclosure are not limited to the number of pockets  1104  in  FIG.  11   , more or fewer pockets  1104  may be used. The roof  1106  refers to the top of the exterior of the portable room  1100 , and the ceiling refers to the top of the interior of the portable room  1100 . The pockets  1104  may have a uniform size, such as 14″×14″. In one configuration, the pockets  1104  receive a filter  1108 . The filter  1108  may be any type of material that filters gas, such as air. For example, the filter  1108  may be a mesh air filter, an electrostatic polypropylene air filter, a synthetic air filter, an active carbon air filter, a polyester air filter, or another type of air filter. 
     When air is blown into the interior of the portable room  1100 , via the vent  1102 , the air rises and leaves the portable room  1100  via the pockets  1104 . The filter  1108  within each pocket  1104  filters particles from the air leaving the portable room  1100 . This may be desirable if the air within the portable room  1100  is not clean. For example, if the portable room  1100  is used as a decontamination chamber, the air within the portable room  1100  may be toxic. Therefore, the air should be filtered prior to leaving the portable room  1100 , such that the toxic air does not affect the environment surrounding the portable room  1100 . 
     In some cases, the portable room  1100  may be used as a clean room (e.g., crime scene lab). Therefore, the air entering the room  1100  should be filtered. In this example, when air is sucked out of the interior, via the vent  1102 , new air may enter the interior via pockets  1104 . In this configuration, the new air may be filtered via the filters  1108  of the pockets  1104 . The pockets  1104  may be referred to as filter pockets. 
     Aspects of the present disclosure are not limited to using the portable room  1100  as a decontamination chamber or a clean room. The portable room  1100  may have other uses. For example, when camping in a dusty environment, it may be desirable to filter the air entering the portable room  1100 . As another example, at a work site, such as a construction site, the portable room  1100  may be used as an office, therefore, it may be desirable to filter the air entering the portable room  1100 . 
     As shown in  FIG.  11   , the portable room  1100  may include a mesh material  1110  as part of a door  1112  and mesh material  1110  as part of a window  1114 . Air may also flow in and out of the interior via the mesh material  1110 . In one configuration, a filter  1108  may be integrated with the mesh material  1110 . In another configuration, the mesh material  1110  may be covered to prevent air from entering or exiting the interior via the mesh material  1110 . The mesh material  1110  may be defined on other sides of the portable room  1100  and is not limited to the sides shown in  FIG.  11   . 
     The fabric for the walls  1116  and roof  1106  may be non-porous, such that air may be limited to entering and exiting the interior via the pockets  1104 . In one configuration, the portable room  1100  does not include mesh material  1110  on the sides, such that each side is opaque. 
     As shown in  FIG.  11   , straps  1150  may be attached along a junction of the walls  1116  and roof  1106 . The straps  1150  may be used to attach the portable room to a frame, such as a frame of a shelter. In  FIG.  11   , the attachment point of each strap  1150  to the shelter is illustrated as a circle. 
     Additionally, side straps  1152  may be attached to a junction of adjacent walls  1116 . The side straps  1152  may be used to attach the portable room to a frame, such as a frame or legs of a shelter. The side straps  1152  may be attached to material that extends from a junction of adjacent walls  1116 . The portable room  1100  may also include floor straps  1154  attached to a junction of a floor of the portable room and two adjacent walls  1116 . The floor straps  1154  may be attached to the ground or a shelter, such as legs of a shelter. The straps  1150 , side straps  1152 , and floor straps  1154  may be adjustable in length. Each of the straps  1150 ,  1152 ,  1154  may include an attaching device, such as a hook, to attach to a structure, such as a shelter leg, a shelter truss link, a shelter bracket, or another type of structure. 
     The portable room may also include roof straps  1160 . In one configuration, the roof straps  1160  include a pair of looping straps and a pair of hook straps. The looping straps may loop around a structure, such as an inner truss link of a shelter. The hook straps may attach to a structure, such as an inner truss link or peak beam bracket. 
       FIG.  12    illustrates a cross-sectional view of a pocket  1200  for receiving a filter according to aspects of the present disclosure. As shown in  FIG.  12   , the pocket may be integrated with a ceiling  1202  and roof  1204  of a portable room. That is, the pocket  1200  is an opening in a space created between the roof  1204  and the ceiling  1202 . The pocket may include an opening (not shown in  FIG.  12   ) to insert a filter. The opening may be a zippered opening or another type of opening. 
     The bottom of the pocket  1200  may be substantially flush with the ceiling  1202 . The top of the pocket  1200  may be substantially flush with the roof  1204 . Air from the exterior of the portable room may enter the interior of the portable room via the pocket  1200 . Alternatively, air from the interior of the portable room may enter the exterior of the portable room via the pocket  1200 . 
       FIG.  13    illustrates an example of inserting a filter  1300  into the pocket  1302  according to aspects of the present disclosure. As shown in  FIG.  13   , the filter  1300  may be inserted into the pocket  1302  via an opening  1304  of the pocket  1302 . That is, the pocket  1302  may include three walls  1306  and the opening  1304 . The opening  1304  represents a space between the ceiling and roof to provide access to the pocket  1302 . 
     In one configuration, an opening wall (not shown) covers the opening. A bottom edge  1308  of the opening wall attaches to the ceiling of the portable room. When the bottom edge  1308  is detached from the ceiling, an opening is created for a person to insert the filter  1300  into the pocket  1302 . That is, because the ceiling and roof are flexible, the material of the ceiling may be pushed upward to create a temporary opening when the bottom edge  1308  is detached from the ceiling. In another configuration, a bottom portion of the pocket is detachable from the ceiling to allow the filter  1300  to be inserted into the pocket  1302 . 
     The top portion of the pocket may be integrated with the roof. The top portion may be a mesh-type material to allow air to flow through the filter. The bottom of the pocket faces an interior of the portable room and may be integrated with the ceiling. The bottom portion may also be a mesh-type material to allow air to flow through the filter. The top portion and/or bottom portion of the pocket are not limited to mesh-type material. Other materials are also contemplated, such as a clear material to create a sunroof. 
       FIG.  14    illustrates an example of a pocket  1400  according to aspects of the present disclosure. In the example of  FIG.  14   , the pocket  1400  is illustrated from a ceiling-facing view within a portable room. As shown in  FIG.  14   , a bottom of the pocket  1400  is substantially flush with a ceiling  1404  of a portable room. The pocket  1400  also includes a sealable opening for receiving a filter. 
     The sealable opening comprises an attaching device  1406  at an edge  1408  of a bottom portion of the pocket  1400 . The attaching device  1406  may be a zipper or other type of fastener, such as a hook and loop fastener. The attaching device  1406  is used to attach and detach the edge  1408  of the bottom portion the pocket  1400  to the ceiling  1404 , or a portion of the ceiling  1404 , of the portable room. The portion of the ceiling  1404  may be a lip  1402  that extends beyond one of the walls of the pocket  1400 . 
     When the attaching device  1406  detaches the edge  1408  of the bottom portion from the ceiling  1404 , an opening is created for a person to insert a filter into the pocket  1400 . That is, because the ceiling  1404  and roof are flexible, the material of the ceiling  1404  may be pushed upward to create a temporary opening when the attaching device  1406  detaches the edge of the bottom portion from the ceiling  1404 . 
     Aspects of the present disclosure are not limited to inserting a filter into the pocket  1400 . The pocket  1400  may receive other types of material or items. For example, the pocket  1400  may receive transparent material to provide a sunroof to the portable room. As another example, fans or heaters may be inserted into the pockets. The fans or heaters may be integrated into a housing that fits the dimensions of the pockets  1400 . Power may be provided to the fans and heaters via a battery or external power source. 
     In one configuration, a floor of the portable room is removable. The floor may include walls that are attached to the bottom of the walls of the portable room. For example, the floor walls may attach to walls of the portable room via zippers. The floor may be removed for cleaning, disposal, or other needs.  FIG.  15    illustrates an example of a removable floor  1500  according to aspects of the present disclosure. As shown in  FIG.  15   , the removable floor  1500  includes four walls  1502 . Each wall  1502  of the removable floor  1500  may attach to a wall  1504  of a portable room  1506 . The walls  1502 ,  1504  may attach via a connector, such as a zipper.
