Customer Ratings & Reviews

I have been purchasing this replacement filter for my Blue Air for the past 2 years. Though cheaper aftermarket filters are available elsewhere, buying OEM gives greater peace of mind, and it isn't that costly - I almost always buy it through Gift Certificates that BB offers through its rewards program. The filter has been a silent crusader on its sanitary mission pairing well with Blue Air machine.

The filter is easy to put on, but can be ripped so be gentle.

Indicator light on top of unit turned red to signal a filter change. Easy to do (after reading instructions). See picture for 6 months use in a non smoking, 1 pet house.

I have two of these air purifiers. This filter lasts for several months and is easy to replace. It does a great job. I don’t have to dust as often and I breathe easier with all the allergens getting sucked from the air.

Love this purifier. I have it in my bedroom and it is like a whisper. I can barely hear it. Works great for smoke and changing the filter is fairly easy. I also like the washable outer filter. I have a bigger, more expensive one for my living room but i recommend this one for bedrooms.

I have two of these 311's and recently purchased a third unit. This way I can locate them around my condo to get more even air treatment than I would get with just one large unit. Plus they all use the same filter element, which I keep a few a few of on hand. These are great units, quiet, compact, and their cylindrical shape makes them easy to position without having to rearrange all your furniture!

The filter is great and it last a very long time. The price is a little bit expensive but I guess you paid for the quality.

This marvelous piece of technology literally saved my daughters life! My daughter, who suffers from respiratory ailments, was away for her first year at college. Life in the dorm can be challenging on any number of levels but one thing we did not want her to have to deal with was the air quality. With this unit on constantly she felt that her health was well maintained and allowed her to feel safe and secure. We finally had to change the filter after about six months. In doing so we encountered a bit of a problem with the unit. The good people at the Geek Squad took care of us with a replacement unit. Always trust Best Buy for the help you need

great item helps keep air clean at all times. helps get rid of smells also.

I live in Florida there’s pollen so bad outside. I live in an apartment building and this air purifier is a must! The filter traps everything.

Air filter replacement is a must after some time. These last pretty long and help a lot with the filtering

Filter works great and was easy to replace. Just what I ordered.

Ordered the item in the local Best Buy store. Received and installed the filter as expected.

This works great it lets you know when the air needs cleaned . I would buy again

Air filter replacement. Easy to install for this air filter. Nothing to fear when buying this replacement part.

Fit perfectly in our air cleaner. A bit pricey though.

I have one of these units for a larger bedroom. Similar to the 411, it is easy to swap the filters (slides on and off).

This product works as advertised. It’s quiet, looks good and when i changed the filter I saw all the dirt and dust it actually trapped.

Great filter replacement for the 311. My 311 runs 24hrs a day and this filter lasts.

Great price for great quality catches all dust mites helps reduce bad air quality
