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

Great product!!!

Filters fit the Blueair Pure 411 perfectly, easy to install. They last approximately 6 months.

Arrived quickly and does the job!

A+

Works great as a replacement filter. Easy to install.

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.

I like the quite functioning and ease of replacing it. Works!

It works

This is a replacement filter that fits perfectly.
