Our take on the Arm & Hammer Pure Baking Soda, 5 lb Bag

Arm & Hammer Pure Baking Soda is 100% sodium bicarbonate in a resealable 5 lb bag. It is the standard pantry and household workhorse: it leavens baked goods, deodorizes fridges and carpets, and scrubs without harsh chemicals. The best new price is $14.95 at Amenie as of November 7, 2026, with five stores selling it new. That is roughly $3 per pound, so compare against the 1 lb box if you only need a small amount.
