Bamboo Charcoal bags are a natural way to continuously absorb and reduce odours, excess moisture, and harmful pollutants in your home or space! Unlike other popular odour eliminators that solely mask the smell of odours by releasing a fragrance, the chemical-free and non-toxic bamboo odour bags are fragrance-free. Each bag can be reused for up to 2 years. To recharge, simply place the bag in direct sunlight once a month for at least 1 hour, to release any odours and trapped toxins inside of the pores of the bag. After an hour, your bag will work as good as new! The 100g Bamboo Charcoal Air Purifying bag is perfect for fridges, gym bags, suitcases, and diaper pails! The bags are perfect for pet owners who want to eliminate unwanted pet odours without any maintenance. They can be placed next to litter boxes, cages, and crates to deodorize the smell of your pets. The bag's compact design allows them to be easily portable for travel and small spaces. The bag's compact design allows them to be easily portable for travel and small spaces.
