Mann Hummel 16x20x1f Fiberglass Air Filter Merv 4

Product Description

The MANN HUMMEL 16x20x1f is a fiberglass panel air filter rated MERV 4, designed for use in forced-air HVAC systems in residential and light commercial applications. Measuring 16 x 20 x 1 inches, this filter fits standard return-air grilles and air handler filter tracks of that nominal size. At MERV 4, it captures larger airborne particles such as pollen, dust mites, carpet fibers, and standing dust, providing basic filtration to protect blower components and heat exchanger surfaces. HVAC technicians and maintenance personnel install this filter as a routine maintenance item during seasonal service calls or scheduled filter change intervals.

This filter is suited for residential furnaces, central air conditioning systems, and air handlers that use a standard 1-inch nominal filter slot. The 16 x 20 x 1 inch nominal size fits a wide range of common return-air openings. Its fiberglass media construction is lightweight and offers low resistance to airflow, making it appropriate for systems where static pressure must be kept low. It is a practical choice for basic dust and debris control in systems that do not require high-efficiency filtration.

Key Features

• MERV 4 rating captures large airborne particles including pollen, dust fibers, and carpet lint

Installation Notes

A licensed HVAC technician or qualified maintenance professional should set the system thermostat to the off position and shut down the air handler before replacing the filter. Confirm the actual filter slot dimensions against the nominal filter size before installation, as actual dimensions may be slightly smaller than nominal. Install the filter with the airflow arrow on the frame pointing toward the blower and away from the return air duct. Dispose of the used filter in accordance with local waste disposal requirements.
