I expected thicker filter. It is even hard to put it on it's place due to being very thin. Doesn't stop any odours.

It's brilliant for tracking. The only issues are that cats often wee in the gaps so makes it tricky to clean, and odour control isn't the best.

I have now purchased 3 of these litter boxes and have always been pleased with their appearance though you will need a larger space to house them. I find they are quite easy to clean and practical to use though I do purchase the giant pan liners for the base tray. I am pleased to see that the new version of this Booda has a new filter at the top which cannot fall down which was the only weakness I felt in the original design.

Cat loves her privacy, took a while to walk up the steps, but now she loves it, looks fun in the hOuse, quite big, but very discreet. No smells, no litter trail, Puuuuuuurfect 10/10 highly recommend

Good for large cats. More attractive than tray. Needs a cover over the filter to stop cat pulling it out. The lid does not fasten to the base so you can not carry the whole unit by the handle. Does reduce litter tracking. Not worth the money really.

It completely absorbs the smell from the litter box. We use it together with Sepicat litter—the bag is white and pink (clumping)—and it's the perfect match.

They absolutely don’t fit in my litter tray, I had to cut them. The material doesn’t seem ‘technical’ at all, it’s just simple foam, like the kind you get when you receive a parcel packed with foam. We’ll see how it goes with use, but for now it seems completely pointless to me.

It does its job. Not bad.

Very practical

The filters are a bit thin, but you can easily cut them to size and slide them into the lid of the litter box. Compared to other, more expensive products, this is perfectly sufficient for me to reduce the "aroma". Of course, it doesn't filter it out completely.

Good and effective, can cut all sizes.

Super, you just cut as much as you need.

Unlike the typical filters you get in a pack, these are terribly soft and getting them into the slots is a nightmare. They’re easy to cut and I think they work, but it’s really hard to fit them into the toilet, so that’s why I’m giving 3 stars.

Regarding the 1 star given, if the material was thicker it wouldn’t fit the small area on the litter box. I’ve given 4 stars because, instead of one single piece to cut to your own size, there are 3 separate pieces, so I’ll end up wasting some.
