Arm & Hammer Fridge Fresh™ Refrigerator Air Filter & Freshener

Arm & Hammer Fridge Fresh Refrigerator Air Filter takes Baking Soda out of the back of the fridge and out of the box. 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.
