Arm & Hammer was founded in the year 1846 and ever since then it is been a popular and trusted brand. This trust is built upon their commitment to purity and quality and is appreciated by consumers today who value alternatives to products with harsh chemicals or those which may harm the environment. The Arm & Hammer Fridge Fresh Baking Soda is great to keep your food in the fridge fresh and to stop from the odors to mix. It sticks to the inside of your refrigerator and exposes two times more odor-eliminating Baking Soda than a regular 1 lb.box. We recommend changing your Fridge Fresh Refrigerator Air Filter every 30 days for maximum freshness.
