Filter King AF19x27x1A-M11 Merv 11 Air Filter 19x27x1

Product Description

The FILTER KING AF19x27x1A-M11 is a MERV 11 pleated air filter designed for residential and light commercial HVAC systems. With a nominal size of 19x27x1 inch and an actual size of 19 x 27 x 0.75 inches, this filter fits standard filter slots requiring a 1-inch depth. MERV 11 filtration captures a broad range of airborne particulates including dust, pollen, mold spores, and fine dust from household activities, making it a solid choice for systems where air quality demands are above baseline. HVAC technicians and service professionals install these as routine maintenance replacements to maintain system airflow and indoor air quality.

This filter is suited for forced-air residential furnaces, air handlers, and central air conditioning systems that accept 1-inch depth filters in the 19x27 nominal size range. It is packaged in a quantity of 10, making it practical for service routes, multi-unit properties, or scheduled preventive maintenance programs where bulk stocking is preferred. The pleated media design maximizes surface area within the 1-inch profile without sacrificing airflow restriction beyond system design limits.
