Review on Bamboo Charcoal Air Purifying Bag 4 Pack - Effective Car Freshener, Closet Deodorizer, Activated Charcoal Odor Absorber by Jennifer Tillman

I bought these air purifying bags mainly to place next to two trash cans in my house. I use odor and dust free litter, add enough baking soda daily and shovel, but a bad odor still develops, especially as the weather warms up. I put the bags of charcoal next to the tray and after a few days the smell was almost completely gone! I ended up putting one next to the trash can in the kitchen, which helped a lot too. At this point I am completely convinced of this product and hope that the charcoal bags will last two years (with monthly reactivation in the sun) as stated.
