Pureness F6 Zeolite Air Filter (3-Pack)

I buy these as a refill for the cat liter. I can definitely tell when it is time to replace them, so they must do something with the smell.

Great price for three of these high quality litter box filters. They are becoming harder to find in stores as the secret is out that they're the best that are on the market. I won't be going to the stores to look for them anymore though. I will re-order right here next time. Thank you!

great filters.

I purchase these for my cat's hooded litter box. They use to sell them in my local Wal-Mart, but have stopped. :( The price is do-able, and they are a worthwhile purchase.

I have been searching for these and finally found them. They are a perfect fit. I did not have to cut them at all. I will be ordering more.

These filters were exactly right for my cats' litter box.

Works great!
