Good air quality, bad fit
Sold as compatible with my 311i Max, while diameter fits, the height on this filter is much shorter than original element. Makes the fabric pre-filter look funny when installed. Still filters effectively, just looks awful.

Doesn’t last
Didn’t notice a difference between the regular filter and this one. But the filter only lasted only around a month.

Thank you for sharing your experience with the Blue Pure 311i Max Allergenblock Filter. We’re sorry to hear it didn’t meet your expectations. We would typically expect the filter to last at least 6 months with regular use, so a one-month lifespan is unusual. We’ve reached out to you directly to learn more and help make this right. Your feedback is valuable as we work to ensure the best possible performance from our products.,Blueair,Blueair Team,clientresponse
