Filter King AF20x30x2-M11 Merv 11 Air Filter 20x30x2

Product Description

The FILTER KING AF20x30x2-M11 is a MERV 11 pleated HVAC air filter designed for residential and light commercial forced-air systems. With a nominal size of 20x30x2 inches and an actual size of 19.5 x 29.5 x 1.75 inches, it fits standard filter slots rated for 2-inch media. MERV 11 filtration captures a broad range of airborne particulates including dust, pollen, mold spores, pet dander, and fine dust particles, making it a capable choice for environments where air quality is a priority. HVAC technicians and facility maintenance staff typically specify this filter tier when occupants have moderate sensitivity to airborne contaminants.

This filter is suited for residential forced-air furnaces, air handlers, and central air conditioning systems with 2-inch filter housings. It is also appropriate for light commercial rooftop units and fan coil systems that accept a nominal 20x30x2 media. The pleated construction increases surface area relative to fiberglass panel filters, which helps maintain airflow efficiency as the filter loads. Sold in a quantity of 10 per pack, it supports scheduled filter replacement programs common in service contracts.

Installation Notes

Filter installation should be performed by a qualified HVAC technician or trained maintenance staff. Always set the system thermostat to the off position and confirm the air handler or furnace blower has stopped before removing the old filter. Install the new filter with the airflow arrow on the frame pointing toward the blower, not toward the return duct. Follow the equipment manufacturer's recommended replacement interval, typically every 60 to 90 days depending on system runtime and site conditions.
