Feelava 6 Pcs Replacement Filter for Cat Litter Box Square Shape Carbon Filters for Hooded Cat Litter Tray Toilet Litter Pans Replacement Filters Odor Filters

Great product

Easy to cut to size. A little thicker than I expected so was a bit tricky to squeeze in to the opening but fairly good at stopping smells from the litter box

I hadn't replaced the filters in the cat litter try for years, decided to buy these and can't believe I didn't sooner!!I found this best value, good thickness, easy to cut - and definitely works (not for how long though!)

These are good to use, I had to trim them to fit the litter tray I have. They’re also a little too thick for mine because the plastic covers pop off sometimes, but they help with the smell!

These are amazing! They work so much better than any other filter I’ve used before. Very thick so have to be wedged in. The nice thing is they can be cut to size so I get two uses out of each filter. They last ages too! Will definitely be buying again :)

This is simply a loose sponge sheet, no filtration property at all. See the photos, you can literally see through it. So anything can pass unimpeded through it.Waste of money ... though not much money so not worth the hassle of returning. I'll find a use for it somewhere.

Bought for Curver covered litter tray. Each filter needs cutting in half with a bit trimmed off the short side but is ideal, so for this sized litter tray you get 12 individual filters. (They are thicker than the original but the lid covering the filter still closes.)

Best to check thickness before ordering
