Removes odors in enclosed spaces remarkably well

So I ordered a jacket from Walmart and it stunk of chemicals. I washed it multiple times with Oxyclean and it still had a lingering chemical smell. I used a similar charcoal product on an old leather jacket I had that smelled and it worked. Thought I would give this a try. Threw my stinky jacket into a trash bag with this inside, tied it up, and let it sit for a couple of days. That smell disappeared completely and never returned. I ordered more for my closet and it works well there too.

I love it

I use it in my cat room with all the cat litter and it removes the smell very well and is odorless so it doesn't bother the cats. Also very easy to use just open it and place. We had bought multiple of these now.

Works!

This really does work to suck up odors. We had a lot of musty smells in our new home after our stuff sit in storage for 6 months. This took the smell away within a few days. It has a pleasant scent that you can't really smell unless you get super close to it.
