I like the Aireox brand air cleaner, and usually I have it in the bedroom, where I feel it does make the air much better, and is good for me, since that is where I spend the most hours. I cough less, I breathe better, with it, and I personally don't have any of the problems mentioned in above posts, that others have had.
All of them make some sound, and I am sensitive to noises, but they need to have a motor and fan, to move the air about the room.
I selected this one, partly because the sound is not loud or rattily or uneven.
I also like this one, because the filters together in one replacement unit, are easy to slide out the old and in the new)
the filter materials clean out more different things, than the cheaper machines that are sold that are made to only clear out the largest particles.
I would look for one with a tiny size micron filter (the tinier number, the better imo) in order to get the most of vapors as possible, in addition to the larger air particulates, that most any air filters get.
This one is very portable, which i also like, because it helps me in any other room, if it's brought there, for a few hours.
I can tell that it does noticeably clean out things that are problematic, (smoke or fumes or odors, or dust)
when taken to any room.
I don't believe my effects are a placebo, because most anyone can notice the difference in the air in the one room it is in, whenever taken places.
In fact, I wouldn't go to any hotel room without it. Or visit overnight anyplace. It clears out the noticeable scents in any room, in max of a couple of hours.
Yes, when the filters are changed, it does get vacuumed out and wiped out. You can even vacuum the outside in between.
I myself, I don't find any problems with it. Other than the expense of the initial purchase, plus then you must buy replacement filter sets, for any that you buy. It wouldn't be worth buying any, if one couldn't buy the filters and replace them.
I am sharing my own experience with it, in case it helps you or anyone else, not to contradict anyone else's info or input or ideas or experiences. I thought it would be helpful for me to add mine. I live where it's dusty, plus, car exhaust fumes and other peoples cleaning chemicals and perfumes, etc, get into my apartment, so it's worth the big expense of it, to me, personally.
