BLUEAIRBlue Pure 211+ Auto Genuine Replacement Filter, Particle and Activated Carbon, fits Blue Pure 211+ Auto Air Purifier

Works well. Relatively quite. You get used to it in the background. I have had for almost 2 years not. Replaced the filters with OEM filters. Very easy. Well engineered product. No funky smells as some have claimed. Use OEM filters. Would recommend replacing every 6 months if you need activated charcoal for pet smells etc. otherwise a once a year would probably work for most folks.

Perfect fit, like in the past, good quality, fair price. May buy a backup. °°°°°

Expensive but it works! Help so much to keep the indoor air fresh and clean.

Fit perfectly in my several years old Blueair machine - easy to remove the old, unfold and insert the replacement filter. The last one went for years! Excited for good quality products, always. Arrived on time and quickly.

Hate how expensively they are. However, they do a great job. We keep ours in the kitchen so it has a hard job. They are easy to install and come well packaged.

Fits perfectly. This is the right product for my air cleaner.

It’s easy to install and does an outstanding job at keeping the air in my home fresh and clean. I really appreciate the combination of particle and activated carbon filtration—it's excellent for capturing dust, pet dander, and odors from cooking or even outdoor pollution.Since using this filter, I’ve noticed a significant difference in air quality. The filter also lasts a good amount of time, and the indicator on my purifier makes it easy to know when to replace it. I love that it’s a genuine product, so I trust the performance and fit without any issues.If you want to keep your air purifier working at its best, this replacement filter is a must-have. Totally worth it!
