If sweet-smelling room deodorizers aren't your thing, here's something to consider: the Moso Bag, a natural air-purifying bag containing moso bamboo. What's so great about that? Moso bamboo is said to absorb and filter odors, pollutants, allergens and bacteria while dehumidifying to prevent mildew, mold and moisture. What's more, it's fragrance-free, unlike some air fresheners that mask odors by covering them up with other scents.
