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

These replacement pre-filters wash up great. The quality is great. The quality of the fabric is exceptional — soft, durable, and long-lasting. Easy to use. The colors stay vibrant after washing.

Exactly what I needed, thank you

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.

Work great but the green colored filter is an awful color.

They fit well and work well.

I Love these air purifier sleeves. They catch a lot of dust, cat and dog hair, and can be easily washed in the washer. The sleeves should be washed & dried separately.

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

Fit well on the blue air purifier as stated!👍

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.

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.

These are almost the same as the brand-name ones, but are a lot more affordable. Colours look good too. Works and fits well.

They're OK they're a bit thin they're usable, but the ones that I originally purchased were much thicker

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