Filter King AF12x14x1-M11 Merv 11 Air Filter 12x14x1

Product Description

The FILTER KING AF12x14x1-M11 is a MERV 11 pleated air filter designed for residential and light commercial HVAC systems. With a nominal size of 12x14x1 inches and an actual size of 11.5 x 13.5 x 0.75 inches, it fits standard filter slots sized for 1-inch media. MERV 11 filtration captures a broad range of airborne particles including dust, pollen, mold spores, pet dander, and fine dust from household activities. The pleated media design increases surface area compared to fiberglass panel filters, supporting longer service intervals while maintaining adequate airflow across the system. HVAC technicians and facility maintenance staff install this filter as part of routine preventive maintenance on forced-air systems.

This filter is suited for residential furnaces, air handlers, and central air conditioning systems using a 12x14x1 nominal filter slot. It is appropriate for applications where improved indoor air quality is a priority without significantly restricting airflow. MERV 11 performance makes it a practical choice for households with pets or occupants with mild allergy concerns, as well as light commercial settings requiring a step above basic filtration.
