Review on Wyewye Activated Bamboo Charcoal Air Purifying Bags - Natural Fresh Odor Absorber & Moisture Eliminator Bag for Cars, Closets, Shoes, Homes, Basements - Pet Safe, Super Large Capacity 2000g (2 Pack) + 500g Charcoal Bags (4 Pack) + 220g (2 Pack) + 100g (2 Pack) by Motogp Portillo

These Bamboo Charcoal Air Purifying Bags come in 3 sizes: -- two large bags (500g each) -- four medium bags (220g) -- two small bags (100g) - grams ). note: a rope is attached to each of the two small bags with a ring. Each little pouch also has a button and when I untied the tiny string surrounding the button there was a small empty compartment. I'm not sure what it's used for as these packages don't come with instruction manuals. I love that these air purifier bags contain bamboo charcoal and are free of toxic ingredients. I didn't smell any odor while sniffing these packets. I have placed these bags in places with odor issues. They eliminate odors well. With my shoes, however, the little bags didn't help as much as I'd like as I could still smell when I sniffed the inside of the shoes. I left these bags in the sun for 6-6 minutes at first. 8 hours to activate according to the instructions on the product description page. These bags save us money as we can reuse them after leaving them in the sun for at least 2 hours a month. an affordable way to deal with most smelly odors.
