3M Filtrete FAP02-RS Ultra Clean Air Purifier
If you are looking for an air cleaner that will actually clean the air, as opposed to spray ions everywhere which may or may not have any effect, this is the one for you.
First of all, 3M is one of the leading manufacturers of filtration material, trusted by manufacturers (clean rooms) and health care institutions all over the world, so you know that their filters are more than good enough for home applications.
Second of all, the best way to clean the air is to suck it through something which will hold onto the particles there in?that's how a Filtrete filter works. Does it work? I keep it in below-grade room which is a hair over 160 sf (rated capacity for the filter) with no air circulation which has had smelly cat puke issues. It took about three hours to remove that smell.
When we painted the room with a paint sprayer, it took about 2 days to clear all of the paint smell out (2 coats of primer plus 2 coats of main paint over the walls and ceilings). Left on all of the time, the room always stays fresh and clean. When I put it in a 100 sf room which had housed a catbox for a year and was VERY stinky, within a couple of days, the room was odor free.
The main problem with the unit, other than the cost of the filters, is that if you leave it on, especially on one of its higher settings (which you shouldn't need to do if you just leave it in the room and on) you can definitely feel air moving and hear a slight fan sound.
If you want to cool a room and don't mind a little bit of background noise, it's great. If you want the room to be completely quiet, or you do not want to cool it, best to keep your Ultra Clean Air Purifier on the low setting.
Pros:
-Relatively Affordable
-Works Extremely Well
Cons:
-Filters are very expensive
-Is audible on higher settings
