baggy
Does not fit as well as the one that came with the 311i Max. It is baggy at the bottom and top and looks does not fit well.

Thank you for sharing your feedback on the Blue Pure 311i Max Pre-Filter. We’re sorry to hear the fit is not as expected, as the pre-filter should sit smoothly around the unit. We’ve reached out to you directly using your contact information so our team can help look into this and assist further.

Pre-filter too small!
I love that the pre-filter comes in different colors and is washable but when snagged by the cats I want to replace. Why is it whenever I buy a new one it doesn’t fit the same?

Thanks for the thoughtful feedback on the Blue Pure 311i Max Pre-Filter. We love hearing that you enjoy the washable colors. The fit difference you’re seeing is likely due to mixing up the Blue Pure 311i Max and the slightly taller 311i+ Max, which use different pre filters. Here's direct link to the correct replacement filter and pre-filters for your unit: https://www.blueair.com/collections/311i-max-2

Blue Pure 311i Max Pre-Filter
We live a few houses away from a very busy road and I’m certain this helps us breathe better air.
I typically hand wash it and I’m blown away at how much filth comes out of it! Just looking at it, one would never know how dirty it really gets. I bought spares so it’s always ready .
