Small size and no filter change makes this perfect for small rooms
I like the small size and no filter needed features in this inexpensive air purifier.  It plugs in to an outlet easily and produces small amount of white noise. Works well when used in combination with larger Germ Guardian units in other rooms.  My two plug in units are used in a small powder room with a litter box and the vanity bath area in my dressing room attached to a bathroom.  Our house is equipped with UV lights and strong filters on total house air conditioning/heating equipment as well. I also use an IQ air purifier unit for my large open plan living/dining/media room combo.  Needless to say I can't tell which air purifiers are doing the best job, but in combination they keep my house clean of dust, odors and most allergens.
