An portable air filtration and air purification apparatus (10; 182; 240) comprising: an enclosure (14; 186), the enclosure having a top, a bottom, sides and a rear; a first air channel (26; 210) located in the enclosure; a second air channel (30; 214; 322) located in the enclosure; a divider (34; 206) that separates the first air channel from the second air channel; a first filter (46; 226; 280) located in the first air channel, and in direct fluid communication with the first air channel; a second filter (86; 230; 293) located in the second air channel, and in direct fluid communication with the second air channel; a first air blower (38; 198; 256) configured to pull air from the ambient environment generally into the first air channel, moving said air through the first filter, and returning said air into the ambient environment, creating generally a first air stream; a second air blower (78; 202; 260) configured to pull air from the ambient environment generally into the second air channel, moving said air through the second filter and returning said air into the ambient environment, creating generally a second air stream; a control system that controls the activation and deactivation of the first and second air blower, such that the control system is configured to operate the blowers independently or together, characterized in that the control system is configured to operate in at least three operating modes: a first operating mode such that the first air blower is running simultaneously with the second air blower; a second operating mode such that the first air blower is running while the second air blower is not running; and a third operating mode such that the second air blower is running while the first air blower is not running or the control system is configured to operate in at least two operating modes: a first operating mode such that the first air blower is running simultaneously with the second air blower; a second operating mode such that the first air blower and second blower is running independent of each other. an enclosure (14; 186), the enclosure having a top, a bottom, sides and a rear; a first air channel (26; 210) located in the enclosure; a second air channel (30; 214; 322) located in the enclosure; a divider (34; 206) that separates the first air channel from the second air channel; a first filter (46; 226; 280) located in the first air channel, and in direct fluid communication with the first air channel; a second filter (86; 230; 293) located in the second air channel, and in direct fluid communication with the second air channel; a first air blower (38; 198; 256) configured to pull air from the ambient environment generally into the first air channel, moving said air through the first filter, and returning said air into the ambient environment, creating generally a first air stream; a second air blower (78; 202; 260) configured to pull air from the ambient environment generally into the second air channel, moving said air through the second filter and returning said air into the ambient environment, creating generally a second air stream; a control system that controls the activation and deactivation of the first and second air blower, such that the control system is configured to operate the blowers independently or together, characterized in that the control system is configured to operate in at least three operating modes: a first operating mode such that the first air blower is running simultaneously with the second air blower; a second operating mode such that the first air blower is running while the second air blower is not running; and a third operating mode such that the second air blower is running while the first air blower is not running or the control system is configured to operate in at least two operating modes: a first operating mode such that the first air blower is running simultaneously with the second air blower; a second operating mode such that the first air blower and second blower is running independent of each other.
