Awesome multi layer filter. Its nice that it folds flat. It lasts much longer then I expected! Feels higher quality then the cheap aftermarket filters.

Dual Action Power: The combination of particle and carbon filtration sets this replacement filter apart. The particle filter efficiently captures airborne particles, including dust, pollen, pet dander, and other allergens, ensuring that the air you breathe is free from common irritants. The activated carbon layer is equally impressive, effectively removing odors, smoke, and volatile organic compounds (VOCs). This dual-action approach contributes to a healthier indoor environment.

The clear instructions provided make the installation process straightforward, and it takes only a matter of minutes to have the Blueair Particle + Carbon Replacement Filter in place.

Consistent Air Quality Improvement: Throughout its extended lifespan, the filter consistently delivers on its promise of improved air quality. I've noticed a significant reduction in dust particles, and the air in my living space feels noticeably fresher. The filter's ability to maintain this level of performance for an extended period without a decline in effectiveness is a testament to its high-quality construction and filtration capabilities. Cost-Effective Solution: While some replacement filters may seem more affordable initially, the Blueair Particle + Carbon Replacement Filter proves to be a cost-effective solution in the long run. Its extended lifespan means fewer replacements, saving both time and money in the maintenance of the Blue Pure 211+ Auto Air Purifier. Conclusion: In conclusion, the Blueair Particle + Carbon Replacement Filter for the Blue Pure 211+ Auto Air Purifier stands out as a reliable, long-lasting solution for maintaining indoor air quality. Its dual-action filtration, effortless installation, and extended lifespan make it a top choice for individuals seeking a cost-effective and efficient way to keep their living spaces free from airborne particles and odors. This filter undoubtedly contributes to a healthier, more comfortable home environment.

This filter is phenomenal. My daughter lives in fire country, and when they were smoked out, these filters saved them and my grandson who has occasional asthma. I have allergies like crazy, and I use mine in the bedroom and the living room. I also have four dogs and a cat, and two parrots… This thing really works in my home

I have been using two different Blueair Air Purifiers for 3 years and am highly satisfied with the product. The carbon replacement filter lasts a long time (a year or more!) Easy installation. We use it almost 24/7. The filter does its job splendidly. The only con is its price on the expensive side.

It’s actually very easy to replace but it’s very expensive for a filter. I wish the filter would be just the paper to replace and not also the plastic frame around it. I’m sure it would be cheaper to buy that way, if there is just the filter to be replaced. And the filter has to be replaced every three month for $ 70

It is a very nice quality filter. That's why i am giving it a five star rating. However, the cost of this filter at almost $70 is outrageous! Had I paid closer attention to this when I purchased the unit, I may not have bought it.

This was exactly what we needed! it was so easy to install - working in just minutes. Ordered online & picked it up within an hour. So glad Best Buy had the item stocked that we needed. Thanks!

I built a small room (200sf) to have whisky & cigars, so I did some prior research regarding the most efficient air purifiers for cigar rooms. The Blue Air 211+ was one that was on most lists. While not the top rated, it had good reviews and was priced right for me. After 3 months use, it has performed up to my expectations. It is very efficient as the indicator light switches from blue to red immediately when it detects any change in the atmosphere. It is powerful enough to cycle the air in my room at least 4-5 times per hour. After a cigar session with 2 or 3 friends, it will switch back to blue light in about 20-30 mins after we're done. It will take about 3 days to completely rid the room of any cigar stench. For me, great job! Very happy with this air purifier.

The filter is a bit on the expensive side, but it's worth it. I keep the Blueair on all the time and you can certainly tell the difference in the air's quality

I have this air purifier and needed a new filter. Easy to replace and works great. Only con is the price but this is how much this filter is everywhere if you don’t want generic.

Wonderful overall... a must have. Don't hesitate and buy it! Great quality, keeps air fresh

Works as intended. Replacement was easy to install and it worked as intended.

This filter works good with the Blue Air 211+ Auto. Will not use imitations

Works great for smoke and other smells from cooking and animals. Air quality seems much better since start of use.

This is a wonderful product, love my clean air in my home

Amazing product! We installed this in our bedroom where we had stale air and an occasional musty smell. Within 24 hours, our bedroom smells fresh and clean and our allergies have greatly subsided! I couldn't give a higher recommendation, this is the best air purifier we have found.

Best air purifier, it automatically adjust according to the air quality. I have 3 of them a one large for living room, medium size for bedroom and a small for home office.

The filter fits and does what it's supposed to do. What more is there to say?

Helps my allergies go away and provides me with a sense of refreshment.

Our Blue Pure 211+ air purifier let us know it was time to replace the filter. The Blueair Replacement Filter for our Blue Pure 211+ Auto Air Purifier was very easy to replace and works as expected.
