Excellent efficiency in size vs volume of filtered air. I have 3 of these units, with 2 of them being on the noisy side on setting 3, and the 3rd is not. On setting 2 the noise is minimal, and setting 1 barely audible unless right next to the unit. They are a bit heavy, but very well made, not cheap plastic, but a full metal housing. The size, shape and design will fit most anywhere, as I have them against a wall and behind a chair. When coming across great deals, I will not hesitate to purchase more of these units for the home and office!

I bought this one used. I expected to have to replace the filter immediately, but it had very little use which was a very nice surprise. The front had a slight "bend" in it which is barely noticeable. I am very happy with my purchase because it did a great job of getting rid of a slightly funky smell. It's extremely quiet and just sits there doing it's job. I have tried several different air purifiers and this one works better than any of the others.

I have ran SEVERAL air systems, including Aerus, and these by FAR out perform them ALL! Really cleans the air and leaves a crisp smell in the air. Unbelievable units! Completely amazed. I'm very hard to please when it comes to air quality in my home and in my company in Overland Park, KS Point One Janitorial Services (President, CEO)
