We already had yhe unit and just needed to replace the filter. It really works well on helping keep our air clean from dust and pollens. We have woods in our backyard. Spring is terrible for pollen.

My units
They work great. I’ve had them for years, very little noise. Although the new ones have more to offer I’m staying with what I have.

Easy to replace
Easy to replace (every 9 months). Relatively low noise and does appear to filter the air well.

My 211+
I’ve had no problems with my 211+. It runs 24hours, 7 days a week. You don’t even know it’s in the room. I will always have a Blue Air purifier.

Excellent smoke eaters
We bought two of the 211+ units a few years ago mostly for wildfire season when smoke gets intolerable. They work extremely well and we actually get closer to a year out of the filters. Low setting is quiet and they do get louder when cranked up which we only do when the outdoor pollution is bad. Only drawback that we have with the units themselves are that the controller is way too sensitive and our cats have often changed the speed by walking by wagging their tails and hitting the button. Maybe redesign the control button.

Easy to Replace Filter
Filter was very easy to replace. There is a noticeable difference in smells in the apartment from before the old one was replaced to now. Lasts a good amount of time for the price.

A filter that filters
These "please rate our products" requests are so stupid, because a filter either works or it doesn't. There really are no gradations.

Clean Air
I am very happy with the product it does what it says. Air in the room feels much better cleaner and it takes out the impurities which are very noticeable and I feel better thank you.

Keeps me breathing
I have asthma, along with many plant allergies. My Blueair makes it possible for me to get a good night’s sleep, even during the worst of the allergy season. Plus, it keeps me breathing during fire season; my bedroom becomes my smoke-free sanctuary! I don’t know I got along before I got a Blueair!

Love our 211
We have two 211 Blue air purifiers, they are great. They are on 24/7 and keep the air clean. When pollen and allergens blow in the air I can count on the air in our home being clean. I just purchased two more 511i, that’s how much I love and trust this product.

Cleaner air!
We've had it a few years, and subscribe to get new filters every 6 months. A bit pricey, but we see the dust on them every time we replace them -- and see they do work! Highest rating on Consumer Reports for anything near their price range. So great value.

Easy to order
These work great, I just wish there was a way to recycle the plastic from the filter or for it to not contain plastic!

Works great!
We had a tree come through the roof in a windstorm and the renovation was quite messy. I put the filter on after we could go back to sleep in another part of the house. That filter was so dirty. New one is great!

Always surprised
I am always surprised when I go to change the filter. It is quiet and runs in the background, but I am always shocked at the amount of dust and dirt that it gathers in the quiet.
