Review on MYTHO Bamboo Charcoal Air Purifier Bags - Powerful Activated Charcoal Odor Absorber and Eliminator for Home, Closet Deodorizer - Natural Air Purifying Bags by Jennifer Rosell

I bought these after trying other charcoal bags (which were larger and more expensive). They worked wonders and I still wonder how! Unlike other packs I've tried, I didn't have to activate them by placing them in the sunlight first, and I noticed that they got rid of my new pup's odor and urine stains for about a day! Miraculously they do NOT keep the smell in the room he visits! I may even order more for future needs.
