Customer Ratings & Reviews

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.

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!

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!

I bought the Blue Air air purifier for myself and went on to buy one for each of my sons. It does the job well. I replace the filters every six months and our homes smell fresh and allergies are no longer an issue.

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.

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.

I wasn't sure I'd noticed a difference in air quality using a hepa filter like this, but I really can. The air in our bedroom doesn't feel as "heavy" anymore. Also, we can use this as a white noise generator so we sleep even better at night. A little pricey for a filter, but they last awhile so the cost per month is reasonable.

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!

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)

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.

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

Does the job. Been using this air purifier for about 4 years.

Easy install. Works well. Filter is effective. Excellent machine.

This filter seems to work fine. It appears to be the right fit for my air purifier.

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
