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.

This filter was easy to change and fit my machine perfectly. The filter lasts 6 months.

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

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

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

These are a great affordable filter replacement for the blue air filters! Highly recommend!! 10 out of 10!

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.

Very pleased. Exactly what I ordered & the ship time was amazing! Ill order from here again!

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

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.
