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

This BLUEAIR Blue Pure 211+ Auto replacement filter works perfectly with my Blue Pure 211+ Auto Air Purifier. 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!

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.

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.

With contemporary kitchens, overhead 'hoods' for smoke and grease re-circulate the greasy air back into the kitchen. I bought this, and before starting to cook dinner, we turn this on to "full blast," and it sucks in all the grease in the air and filters it out. If you live in a smaller home or a new 'townhome,' this is the PERFECT solution. We keep it going all day & night on its 'low' setting so that the house always smells clean when entering the home. It's a great product!

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.

For 211 auto; perfect fit, no odors.

works really well for the smoke from the mother in law lol

I purchased BlueAir Purifier in 2020 and finally decided to replace the filter. Online at BlueAir I would have paid almost $70 for this very same filter. I ordered it yesterday evening and received it before day this morning. Thank you for the speedy delivery.
