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 Jocelyn Hernandez

I bought this because my house smells badly. I bought this and there were 4 little sachets in it and I put them around the house. This works because the bamboo charcoal on your back cleans and refreshes the air so it no longer smells. They can be used for up to 2 years and you can reactivate them at any time by placing them in the sun. I will definitely be using them 24/7 for years to come. I felt a difference within the next few hours once I started using them. My house has never smelled so fresh!
