Review on All Prime Bamboo Charcoal Bags Odor Absorber - 4 Pack: Large 500g Bags for Powerful Natural Odor Elimination and Air Purification - Charcoal Deodorizer and Activated Charcoal Odor Absorber for Home Use by Robert Schneider

I am very glad I bought these air purifiers! The packaging is good, they are durable and can be reused! I keep one in our dressing room to reduce moisture and mold. I gave one to my uncle to keep in the car to filter his stale cigar smoke and I keep one in my car to give it a fresh car smell. good breath and prevents mold, mildew and soiling of your belongings - but I'd definitely say they're worth the money! Added bonus: leave them in the sun for an hour and use them again!
