4 Pack 211+ Replacement Washable Pre-Filters for Blueair Blue Pure 211+ air Purifier, Removes Pollen, Dust, Color Include 2 PACK Lunar Rock and 2 PACK Diva Blue Pre-filters

They fit well and work well.

Great quality.

These fit and work great.

Nice set of replacement covers for the BluAir squared filter.

These save so much money on air filters. Wash up nice, easy to put on. I have them on my air purifiers and bought them for my mother's. Saves so much money.

A little thinner than the originals that came with it but they work fine and no complaints on the price. Another bonuse is that you can change colors from time to time. I haven’t tried to wash one yet (I always just throw the originals in the laundry) but I don’t expect any problems.

I love the air purifier, and these work consistently well.

Vibrant colors. Wash easily. GREAT to have so many that I can change frequently. I have lots of allergies and now I can change as often as I want without running out or having to constantly be washing just one or two and waiting for them to dry.

They fit on the 211+. Colors, well don't match the decor but as the last ones didn't fit. ( From a different company)

I love my BlueAir purifier but the parts can be pretty expensive. I really enjoy the quality of the filters and for a reasonable price. I must say I wish the had more colour's.

Love the colour selection as it changes the look of the air purifier.

Good quality and works perfectly with my unit. Saves on filters to have more so you can get more life out of your charcoal filter. Machine wash easily too and a great value for the money.

These work well to catch dust. The original name brand one I have is thicker but these seem to do the job. I change it weekly so the set comes in handy.
