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

All’s good

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.

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

Super easy, came on time

It works

Works well they are correct filter for blueair 411.

The filters were delivered well packaged and on the day they were promised. One of the major drawbacks we have experienced running air purifiers is the cost of replacement filters. Not so with these, they are fairly priced and worth the money.

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.
