Moso Natural Air Purifier is an odor absorber specially designed for refrigerators, freezers and coolers. More powerful and longer lasting than baking soda, this extremely effective air purifier actively captures and eliminates odors, moisture and ethylene gas. The Moso Bag removes odors of all kind, including the aftereffects of a power outage, spoiled produce, leftovers or foods with distinctive smells such as fish or cheese. Filled with just one powerful ingredient: moso bamboo charcoal, this odor eliminator will keep your refrigerator smelling fresh for up to two years! Also keeps your produce last longer by absorbing ethylene gas, a naturally occurring gas from fruits and vegetables that causes them to ripen quickly. Try keeping a Moso Bag in each produce drawer! With routine rejuvenation, the Moso Moso Natural Air Purifying 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. So cool! Space saving suction cup included.
