Great air purifier Helps with my allergies! Filter change when color changes several shades. I change approximately every 9 months but could wait a bit longer.

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.

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.

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.

Very impressed with how much cleaner the air is. I was shocked to see how dirty the filter was after about 6 months of use. My only minor gripe is I wish it removed odors better than it does, but I primarily bought it to remove dust, etc.

Easy to install and remove, and it does the job! Good quality filter.

Blue air purifier has limited allergies, the filter and maintenance keep home air clean. I replace the filters twice a year. I use to go 9 months between filter change, but 6 to 7 months works better as change out is less dusty and little messy. My experience.

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.

The filter is easy to replace and the system has done a great job in keeping the air quality high.

Item was just what I needed for my Blue Air purifier, it was easy to replace this filter! Also, it was ordered and arrived on time just as the store said it would.

This air filter is so worth it. Having clean air is crucial for me I have severe allergies.

Always easy to order this filter from Best Buy. Thank you

Easy to replace. I would recommend this product. Wished the price was lower.

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!

Excellent Product. Does the job! I use this one all the time.

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

I love mt Blu Air 211+! Does a fantastic job helping keep my allergies in check.

The Blue Air 211 air purifier works extremely well. I was somewhat unsure of its ability to capture diesel exhaust, but when that's outside of my residence, I've never smelled it inside. The filters are not cheap, but my health is worth every penny.
