Customer Ratings & Reviews

Lasts ~ 5-6 months (as advertised)......and this is with 2 dogs and a cat. Very pleased with both the purifier and its filtration system.

Quick and easy to change, look how gross that filter is, go buy yourself some clean air!

You can see the difference between a new filter and one that's 6 months old. Minus one star for price, but you can see that it does trap a lot of dust and other things. Super easy to change.

Love this filter. Keeps air fresh. Just wish it wasn’t so expensive.

it filters the air in my air purifier.. simple as that

It does what it's intended, just wish wasn't so darn EXPENSIVE!

The Bluair air purifier is wonderful. This was the replacement filter after about a year of use. Was surprised to see how much it took out of the air. The new one fit perfectly, came exactly when they said it would and starts another year of clean Air. Great price also was available from this website.

I bought this as the first replacement for the filter that came with the Blueaire 211+ I bought about 7 mos. ago. It looks identical, so I'm thinking it's the real deal - unlike what you might get ordering from other certain online retailers - or so I hear. Now, I'm only giving it 4 stars because I really can't tell if the purifier is making a difference. I run it mostly on low speed 24-7 in a large open space, so that could be the problem. I hear to be effective, it would have to be run at high speed in smaller spaces, but at least it should be somewhat beneficial. I do see dust collected on the outside skirt and the inside filter I replaced clearly was dirtier than this new filter. I was hoping this purifier would prevent or at least limit my wife's sneezing fits - and my 16 year old cat has some respiratory issues, too, that apparently is no better after getting this device.

This filter does it's job! I bought this air purifier in July 2021 and didn't have to change the first filter until February 2022. I have a long haired Persian who gets brushed everyday but still sheds a lot. This filter not only cleans the air but sucks most of the cat hair onto the outside cloth cover of the purifier. Does everything I wanted it to do. I do wish it cost slightly less but easy to install.

Easy to replace the old filter once the machine changes color to red. Hold the button down for 5 sec to reset the timer, and we’re good to go with clean air for months!

I've been using these air filters for over a year and the difference in my air quality has made a huge difference. No more coughing, sneezing and ugly smells from cooking and my fur babies. I don't see dust motes floating thru the air anymore either. Worth every penny for wonderful air quality. Very easy to install and replace as needed.

These are great replacement filters and really help the air smell fresh in the house. The filters do last the 6 months, and the light on the air filter will turn from white to orange to red to remind you to replace the filter. It's always shocking when I pull out the older filter compare how dirty it is to the new white filter.

Works great. I could tell the improvement in our home air quality after the first couple of hours. I run one almost constantly and I have to replace the filter about every 6 months. I run another one occasionally and I haven't had to replace it yet (about 2 years)

Immediate difference. Also when swapping the old one you can use just how dirty your house is. A little expensive though ..

This filter is easy to install and works very well. I use my air purifier throughout the day and night. It helps me to breathe much better. I live in an area that has high levels of allergens and this really helps to reduce them inside my home.

I've read reviews about the filters having a smell. I have not experienced that and the ease of use and replacement very simple.

This item lasts very long. Cleans the air very well.

Fits perfect. works great. Love how easy it is to install.

Blu air replacement filter seems a little pricey but there aren’t many options. I don’t believe in buying a knock off when it comes to filters. Runs constantly and last me six months to a year
