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

The book for air purifier recommends to switch out the filters every six months so make sure to have some on hand a little after ordering the purifier. Or you will have to turn off the purifier, locate the book, order the replacement filters and then change it like I did. Not fun for the asthma or allergies during that time.

These filters work great, and for a fraction of the price of the official branded ones, these are amazing.

All’s good

I purchased this air cleaner for my daughters first year of college. She loved it so I purchased 3 more filters, one for each year.

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

This is a replacement filter that fits perfectly.

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.

It was fairly easy with 4 hands. I had difficulty slipping it over cylinder. Used a ramdom users u tube video to instruct me first.

Although these do work as compatible filters for the Blue Air device, they are NOT the same. The inner black backing for the filter is flimsy compared to the real Blue Air filter. It would seem that this will affect how well it works to filter out smaller particles. I guess these are good in a pinch or if you aren’t concerned about smaller air particles. The blue air site says it’s filters capture COVID virus but this filter doesn’t appear to be capable of that.

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.
