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

Work well as orginal filters.

Great value for everything you get.

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.

Super easy, came on time

Blueair was a gift from son, Marcus, to trap the dust buildup in various rooms. After purchasing new filters, we are hopeful that Blueair will continue to rid the dust from whichever room it is placed. It was a tad difficult to replace the blue shield around the filter and make it flush with the unit.

It works

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.

Just as good as the more expensive ones.

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.
