AeroStar 16x16x2 Air Filter

Stepping up to a 2-inch depth in a 16x16 return gets you noticeably longer service life and less static pressure than the 1-inch equivalent. This 16x16x2 Aerostar measures 15 1/2" x 15 1/2" x 1 3/4" actual. The deeper pleats hold roughly twice the debris before pressure drop becomes a problem, which means a longer interval between changes and easier breathing room for your blower motor. MERV 8 handles standard residential dust and pollen. MERV 11 covers pet households and mild allergy concerns.
