This all-natural product is 10x more effective at odor control than baking soda. Effective in garbage bins, compost/green bins, diaper pails, cat litter boxes, small animal enclosures, terrariums, sports/gym bags and more. Rather than masking, it eliminates unwanted odors and deters fruit flies by adsorbing ethylene. Target gases include ammonia and sulphur dioxide (rotten egg smell) plus carbon dioxide and methane. Made of a unique volcanic mineral that causes odorous gases to bond directly to its micro-porous structure. Also absorbs moisture and reduces smelly mildew by acting as a desiccant. Fragrance and phthalates free, it is safe for use around pets and children. Simple to use: Sprinkle Smell Grabber as needed – a little goes a long way! Each canister is 650 grams.
