Innofresh Activated Charcoal Pet Odor Absorber
Review by Marchwind1949 : It seems to work fine!

We purchased the Innofresh Astivated Charcoal Pet Odor Absorber a while ago, and found it wo work reasonably well. In fact, we were so impressed with it, that we just purchased another one.

Review by fndougie : Not for me

This product may in fact absorb some odor, but there is no good way for me to attach it to my cat litter box. Once attached on the inside the cats seemed to think it was a toy and or something to be buried. So it lasted about a day and then got scooped up each time.

Review by alooknac : Using as Shoe Deodorizer

Innofresh sells these in different colors and packaging, for different purposes. From what I can tell, they are all just activated charcoal in a handy container. I have bought the red one (for shoes) and now the yellow one, which is supposed to be for pets but we're using it for shoes.

My daughter puts one in each of her gym shoes. It seems to help and it does not impart any perfumy smell, which we didn't want. I couldn't find these in stores and the deodorizer balls that are sold here and in stores all seem to have fragrances. We are very happy with these.

It looks like a person could open these and refill with fresh charcoal if that was eventually needed.

Review by R. L. Garnett "Lewis Garnett" : Almost too good.

Good product. Almost too good. I'd gotten used to scooping the litter box as soon as my nose wrinkled walking past the cat room door. Now I have to check the box.

Review by Justin : These most certainly work!

The folks saying this product don't work must expect it to scoop their litter boxes for them! We have three adult cats and four rescued kittens using two covered litter boxes, and even with scooping 1-2 times a day and the Arm and Hammer litter box deodorizer, the urine smell would quickly re-assert itself. I purchased a two pack of these with the hopes it would help eliminate the smell instead of cover it up with perfumes like most products out there. At first the cats enjoyed detaching and playing with them, but eventually I was able to fully snap them onto the upper vent and they lost interest. Over the next few weeks, as I would walk by the room with the litter boxes or go to clean them, it was obvious that these were doing a great job of absorbing the offending odors. I'm very happy with my purchase, and in fact intend to buy one of the 6 packs after I finish this review. Some of the other reviewers expect this product to perform miracles and it doesn't, but if you clean your box regularly this product most certainly works as advertised.

I only gave four stars because the yellow plastic holder really needs to be stronger (snap together solidly) to withstand curious kittens, and the clip on the back was just barely large enough to attach on the vent, YMMV. Still, highly recommended!
