3 Pack Blue Pure 411 Filter Replacement Compatible with Blueair Blue Pure 411 Genuine, 411+, 411 Auto and MINI Air Purifier, Package Include 3 Pack 3-in-1 HEPA Filters

I thought we had cleaned the original filter pretty well about a month back. These came in and I couldn’t believe the difference it made in the air quality. By default, these aren’t exactly easy to get on and off, however these included the tabs to pull it into place. Great value and will definitely recommend.

Nice Generic Filters! Works great on my Air Purifiers!!

This is a replacement filter that fits perfectly.

NOT EVEN CLOSE TO FITTING

Do not purchase if you are trying to replace the filter for your blue air pure 411. It is way too small as pictured.. It ripped because it isnt the right size.

Work well as orginal filters.

Great quality. Better price then blue air. But seems to work as good

This filter does not perform nearly as well as the filter that BlueAir themself provides. It does not seem to clean the air of any plastic smell from 3D printers what so ever. The stock filter, however does. I would recommend not cheaping out - buy the OEM option if you plan to use the 411 for air filtering in a room with a 3D printer. This filter may be okay for things like pet dander.

The filters fit well and are okay, but the paper filter material itself isn’t as good and the carbon component is drastically inferior.

Works great as a replacement filter. Easy to install.
