The Moso Natural Air Purifying Bag is a high quality odor eliminator that doesn’t just cover up odors; it actually absorbs them. Without needing batteries or wires, this extremely effective air purifier uses moso bamboo charcoal to magnetically capture odors and harmful pollutants out of the air without giving off a scent. For damp, musty environments the Moso Bag will also absorb excess moisture and regulate humidity. The 300 gram Moso Bag covers up to 90 square feet and is perfect for closets, bathrooms, laundry rooms or small pet areas. Chemical free, fragrance-free and non-toxic, this odor eliminator is a safe alternative to traditional air fresheners that typically contain harmful chemicals and fragrance. With routine rejuvenation, the Moso Bag lasts up to 2 years! Simply place outside in the sun once a month for one hour. After two years as an air purifier, cut open the charcoal bag and sprinkle into your garden to promote plant growth.
