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.

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

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.

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

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

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.

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.

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

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.

The filters were fine and fit as exoected. Thet arrived in good condition

I love that Best Buy sells replacement filters for my blue air purifier. The filters are quality at a good price with free and fast shipping. I also love the various payment options available.

Good customer service..quick and knowledgeable..knew what I needed

We love the Blueair unit, and it was time to replace it with the "red" glowing notice. EZ to replace. A bit expensive for the filter, but it should last a year.

I love my BlueAir air cleaner and so happy I can buy the replacement filter from Best Buy whenever I need one.

I like to have an extra filter in hand to replace in six months. The filter in the air purifier works great, so this should too since it’s the same filter.

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!

Excellent air filter, it is very easy to use. It is quiet. I am very happy with this filter system.

Very easy to replace filter. Unit is quiet unless it is set to the highest setting
