BLUEAIR Blue Pure 311i Max Genuine Replacement Filter, Blue Pure F3MAX, fits Blue Pure 311i Max Air Purifier

Good replacement for existing item

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!

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.

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.

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.
