This is a fridge deodoriser from Arm & Hammer. Baking soda with a larger exposed surface than an open box, which is what makes it work faster.
It earns its place in a fridge that has started to smell of whatever is oldest in it. Compare it on how long it lasts rather than on what it costs the first time — that is usually where the difference shows up.
Arm & Hammer is a Church & Dwight brand; the company runs US plants at Green River, Wyoming and Old Fort, Ohio for baking soda, and at York, Pennsylvania and Victorville, California for laundry and cat litter.
