Blue Pure 511i Max

I love this air purifier

That’s a great air purifier. I had the larger model for years and absolutely loved it, but I’m very pleased with the small, quiet Compact 511. I highly recommend it. I’ve also owned a Shark air purifier, and I wouldn’t buy one again. In my experience, the quality of the Compact 511 is far better.

Quiet operation

This is our second Blueair. We use it in our bedroom. It is almost silent at low speed and very acceptable at medium speed when we are sleeping. It is very effective at filtering the air in our room. We clean the outer cloth filter every 3 months or so and the inner filter annually. We are very pleased this 511i.

Great addition

Could not be happier with this unit that we added to our collection. We have three other blue airs in our home, which are great. We just converted an old playroom to an office and I put this in there and it’s been absolutely tremendous.. very happy.
