Okaysou AirMax 8L 3-in-1 Blue Ultra-Filter Higher Grade H13 True HEPA Filtration System, 1 Pack

Good filter! Great customer service

These machines are wonderful - and we have pets and smoke in the house (I know, I know...) - and Ive tried many over the years. The filters are top-notch and last a good six months. Well worth the money, IMO.

2 things, take them out and just brush them off and they will give you more life, also they are hard to find and obtain, that said when i pulled mine out after 6 years they were full of dust and hair so clearly they are working

Great filter! It works so well!
