The 200 g bamboo charcoal air purifying bag is perfect for cars, pet spaces, nurseries, closets, lockers, and offices! 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 nontoxic 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.
