Envion Therapure TPP220-M Permanent HEPA Type Air Purifier

I must absolutely recommend this product. The Envion Therapure TPP220 Permanent HEPA Type Air Purfier is excellent. Please note that this is a HEPA type product. So, I was just getting over some serious upper respiratory problems when my mom let me borrow hers. I've been using it every night since then. Of course I bought another one so that I could return the one belonging to my mom to her. Anyway, It's been about a month and when by this time I would be suffering from seasonal allergies I am not!! I credit it to this air purifier. Highly recommend it!

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.

Got this for my Mom last Christmas and with 3 cats and a dog it's been working great. Very easy to clean can get a little dusty tho.

Dosent really seem to do much, I'll leave it on for a week straight and check the filter and it's just as clean as before
