This air filter is a miracle worker! We have a problem of neighboring cigarette smoke and very strong cooking odors coming in thorugh shared walls and running this machine eliminated the issue! I even tried a competing air filter and it failed compared to Blueair.
I've bought four of these now, for bedrooms, livingn room and the original offensive mud room with shared walls.
In addition, we have very polluted air quality where I live - from pollens to factories and again, this air filter really cleans up our air!
Thank you Blueair!
