... rarely do you hear the Blueair air purifier, but I certainly know when it is turned off. I have asthma that is now diagnosed as COPD. Without this unit on, I wake up during the night unable to breathe. Blueair has changed my life.
I have tired twice to get a filter for my Blur Air 311 and have been unsuccessful in getting the right size. It appears it does not exist. The site is less than friendly to find my filter. I was able get a refund for the first ones with out returning them but not able to do the same for these so currently stuck. Worn out trying . Took the scissors to it and made it work. So sad.
