These great filters and filter kits by Simplehuman are wonderful for kitchen trash cans, especially. I highly recommend them.

I put it on my kitchen garbage cat lid. It started helping immediately with the stale smell. I love it. Works just like it said it would.

Works like a charm to remove odors! I would highly recommend it!

It seemed better than the cardboard stick-on. But it fell off the first week. My fault? Hard to say. I had forgot about it and must have got thrown out with the garbage. Now I have extra refills with no place to put them...

I'm naturally a skeptic, and so many of these little household items just don't live up to their claims, so I bought it with a healthy dose of ambivalence. But waddaya know ... it actually does its job and does it well. The smelliness really HAS gone away. Shocker.

the filter kit fits perfectly in the top of the trash can, but not so happy with the filter's ability to absorb odor and moisture

I originally bought this for my trash can but ended up using it in my closet to get rid of funky shoe smells. Very unassuming little filter that does a lot of work. It doesn't add scents to the air like a lot of odor absorbers.

This helps keep the kitchen smelling good even with onion peel in the can.

Filter helps keep kitchen odors down.

I had a cat litter box with carbon filters and it helped keep odor under control. When I saw this I didn't know if it would work, especially since we cook a lot and sometimes there's food in the trash. It has not smelled like garbage at all. My only mistake was sticking it right in the middle! Try to stick it a little more toward the top edge of the can so that its not opening or getting in the way when you are trying to change the liners/bags.

I use this in my main bathroom trash container which helps to keep the odor down

The charcoal filter would not adhere to the dome top of my simplehuman trash can so it's usless. It should have been noted when I put in the serial number of my trash can, but it wasn't. Also the filters are of no use to me either. It would probably cost more to return them for a refund that it's worth. I feel I should hve been told that these items would not adhere to the top of my simplehuman trash can.

The sticker was too weak! it fell in the can and was taken out with the trash in the first few days of use!

The odor filter kit did not stick to the lid of the trash can but the bags for the trash cans are great and fit well-- I would recommend them to anyone with the small trash can.

A surprisingly effective little device! We are using it for kitchen garbage odors and for the diaper trash can. Both are working very well to keep odors at a minimum. (Honestly there really is no eliminating diaper odor completely.) The container is easy to install. It is small and stays out of the way.

I have a big trash can from simplehuman, so this filter's size is perfect. It does its job, and it's barely noticeable (unless I keep the lid open all the way).

I don't usually have smelly garbage, but I still smell it just as if I never bought this product.

Must work, there's no stink when I open the lid to my garbage can. Easy to install, still sticking to lid.
