The Hornady model lists an effective capacity for spaces up to 333 cubic feet. This metric focuses on volume, making it suitable for larger enclosed areas like big gun safes or closets. The ATKMAYI unit specifies a coverage of 35 square feet. This area-based metric suggests it is optimized for tighter, flatter spaces where air circulation is limited.
