Definite difference in the room i keep this in. Air just seems cleaner. Changed the filter once so far, and it captured a lot of gunk.

Just 1, not 30.

I had my doubts if this would have strong results. I know there are more expensive filters out there and I need it for a 650 square foot space which is at the space max. I decided to buy an air quality monitor together with this purifier to make sure that is really works. And holy moly! First, you can really feel the difference but that being said, what if it was just our minds playing tricks on us. But the AQ monitor doesn't lie. The air coming out of the machine has a 0 particle measurement. Even the far corners of the room have a 4 or 8 measurement. To keep it in perspective, anything under 50 is good and outside in Toronto it was 65. And although the purifier is big, it is pretty stylish so it looks great. Quiet too. I did a lot of research and this model is much quieter than comparables. I should have bought this a long long time ago. Go for it.

We tried a knock off version and the smell was so gross. These are the only ones that work.

only buy genuine filters!

What more to say, authentic blueair filter
