Pureness F6 Zeloite Air Filter (2-Pack)

Just what I was looking for. When my local Walmart stopped carrying these filters for my kitty potty enclosure, I ordered these filters. Perfect fit, replaced the (rather shoddy) filters from Walmart perfectly. Since it has gotten warmer, the cat goes outside more often so I don't chage the filters as often, but they also seem to last longer than the other brand I used. I will definitely order more of these filters.

Item was as described

Good

The filter is too small and doesn't fill up the entire slot.

They do the job. That about all you can ask.

Adding this to our litter box made a world of difference in smell! I will keep an extra one on hand always.

Not useful at all. It’s totally different size and I don’t think our cats needs that

These filters are very effective at controlling cat box odor.
