The Blueair filters are hospital grade filters that remove particulate down to about 1 micron. The filter with charcoal filters out unhealthy gasses. The Swedish designed Blueair Filter Units are excellent quality with noise levels below ambient bedtime levels (about 30 dbA)

Sold me a filter that was already written down as defective, and returned by a previous buyer. They even wrote the dates when it was bought and returned. I tried it and the smell was horrible, like a car that was leaking gasoline and oil Who sells someone something thatโs already defective.

The best air purifier brand in the market. I have been using Blue Air Air cleaners for over 8 years. Eliminates dust, pollen or even food smell. Sneezing, hay fever and itchiness are gone as well, and my eyelid doesn't feel heavy. I am extremely tidy, but London's air quality is terrible. I would not recommend any other brand than Blue AIr. The filter is heavy on price but your lungs are worth more than that.
