CISNO 2 Packs Air Purifier Replacement Filters (KJ65F-A1), High Efficiency 3-in-1 True HEPA and Activated Carbon Set Air Cleaning System (Fits TCL KJ65F-A2 Purifier)

The Cisno air purifier is wonderful. You can tell the difference in the air. I have it in my office. I close the door and let it do it's work. I'd had people walk in and ask why the air in my office is so much better and it is because of the air purifier. Really helps with my allergies since I work in Austin TX. I think the filters are a bit pricey and hard to get sometimes.

Good calue for money, easy to reinstall, immediate improvement in air quality. We use our purifier for our senior chihuahua's lungs and when the original filter went out her CHF (Chronic Heart Failure) made her start coughing again immensely. Filters came, and her lungs calmed down. Thanks!Con, we couldn't figure out how to get the light on the filter machine to stop flashing red. :(

These filters are supposed to last/be changed every six months. I didn't put mine in until the end of January 2020, and last week I got the light/beeping to replace it. I'm very disappointed because these are expensive. I keep the machine on low or medium, and it only runs when we're sleeping.

The filters are perfectly sized. My only complaints are company-related: the cost of a 2-pack (why is only one filter not available?) & no information from Cisno regarding substitute replacements.

I really like my filters for the air cleaner,but they are a bit pricey. They also dont last very long,but they do the job they are supposed to.

these filters appear to be identical to another filter for Levoit; units fill with lint, pet hair, and dust as expected and work fine after being vacuumed; the filter is good for homes with pets

Purchased these filters to have on hand. I leave the air purifier running on low temp 24/7. Don't want to be caught without a replacement filter just in case I need one.

Cartridge too big.
