It is so easy to replace the filter. I cooked bacon and the air purifier went into action. Love it!

My Blue Air really helps keep my indoors air clean. Especially when wildfire smoke fills our valley. Then it's worth its weight in gold!

Too big

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.
No, I would not recommend this to a friend.

Works as intended

The Blue Pure 311I Max + carbon filter works as intended keeping the inside air clean and removing pet orders (we have a cat). We are happy with your products. Respectfully, Steve M.
