Genuine Filter for Blue Pure 311i Max Air Purifier

Works great and needs replacing every 6-9 months depending on how much your air quality is. I burn wood on a wood stove and have two dogs. So I think it’s great for our space!

After about 9 months in out the box with 13% filter life left on the app it was time to replace it. It does a very great job if you vape indoors a lot or have company that do. It will get loud if you want to dissipate the smoke quicker but it’s usually on max for 2 hours to clear out the room. The size is correct to OEM. I hope to see another 9 months before replacement. Remember to clean your pre filter!

Love the air purifier. Very light weight, quiet. Seems effective at removing particulates. We have a large dog…it seems to help with removing doggy smells.

fits, works just fine.

Wow what a difference in the Air Quality,No Wonder it's #1 rated works incrediable easy setup ,No Noise unless there's a fire even then barely noticeable

The item received was a returned item not packaged well and had slight damage. Otherwise, it works fine. Taking a star off for the packaging of the return item and with damage sold as new.

We have a blue air filter in our family room and had to re-order the filter for this component and it was nice to be able to do it through Amazon and not have to go through the Blueair website to do so and it arrived in perfect condition and was easy to install

These filters worked great with my Blue Air and there were two in the box for what I paid for one on another shop. You do have to measure your Blue Air, the first ones I ordered were two inches too short. These fit perfectly.

Love mine! Use this in my hamsters room and definitely helps with dust and odor. Also we get a lot of forest fires where im from so this is a definite need for those bad days.

If you are reading this before placing your order and you own a 331i+, this is the wrong filter. That + is a larger model and this one won’t fit. Don’t be like Bob. Read the description very, very carefully! 😆😁 On another note, I love my Blue Air!

Fantastic! It eliminates the idor very quickly and I find my place much more cleaner the air that we are breathing

I was pleased to receive the filter I ordered, without delay. With the forest fire smoke heavy and problematic for our area, having this delivery in such a timely manner was most appreciated. All went smoothly, and is working without issue.

Nice design. Love the different settings. Lowest setting is barely audible but can increase if more circulation is needed. Good purchase.
