Envion Therapure TPP220-M Permanent HEPA Type Air Purifier Black

I've been using these air cleaners for several years and find them adequate, but not great. They do help a little, but there are better air cleaners on the market which are much more expensive. I run several of these at a time to make them more effective, but they don't in any way clean the room of mold, which is my only air quality issue. The advantage or disadvantage of this machine, however you look at it, is that it has a permanent filter, and you don't have the cost of replacing a filter every 6 months. However, over the years the efficiency of the filter decreases and, even if you vacuum it, it still remains less effective.

The differences between this model and the larger model are significant and are not only relative to size. The larger model is far superior, and, in the future, I shall not purchase others.

I love this little thing. It's very effective and you only need to clean the filters and not replace them. I've brought 2 so far and will buy another one shortly.

Small, room size, seems to be very efficient, very quiet on low. Bought another one!

It stopped working in a month

Fine, works as described and expected. My secound one. A little noise on Med or High but I am Ok with it..

I like it

I wouldn't know.
