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 Matt Estrada

very well done! Great fabric, great stitching, no huge nasty tag on the side to remove. But they arrived without any protection - just in a dark plastic bag already opened. I've had other bags of charcoal before they were vacuumed. But I threw them in the sun for 2 hours to charge/refresh them when they need it. It's impossible to tell if they need it or not. And there were no real clues in the bag. But YouTube says throw them in the sun for 2 hours once a month and then completely swap them out after 2 years. You can cut them up at this point and use the guts as plant fertilizer. So I love how eco-friendly this product is. It looks good. I put a large one in my son's bedroom because they are boys and smell like them. And another one in the litter box. It seems to work. These articles are pretty cool.
