I got 4 of these to place around my apartment, and I was NOT disappointed! The air was just what I expected...CRISP, CLEAN, CLEAR!!!

For a small device it really works!

First we purchased two units. After running them for six months we noticed that there was less dust and allergens in the air. We now are having to clean the filters less often.

I put one in my room to help with cleaning the air while I sleep and it's made a huge difference. I can smell that the air is cleaner and I have been sleeping more soundly. I will say that the noise bothers me some but its not louder than the bigger air purifier machines so I will deal with it.

Works good
