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

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.

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

This product is too small in diameter to fit the 411 Auto. Filter rips if attempting to fit.

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.

Say no more we love it how the works for our blue air.

Work well as orginal filters.

This was a great addition to my recent ILife purchase. Although the mop pads can be washed I like to have additional items on hand. The items fit securely which I have found wasn’t the case with other vendors.

Super easy, came on time

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.

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