Pro-source PRO19667 Pleated Air Filter 16x20x4 Merv 11

Product Description

The PRO-SOURCE PRO19667 is a wire-backed pleated air filter rated MERV 11, designed for residential and light commercial HVAC systems requiring reliable particulate capture at medium-efficiency levels. The filter uses a synthetic pleated media supported by a wire backing that maintains pleat geometry under airflow, preventing media collapse at higher face velocities. The beverage board frame provides structural integrity during installation and service. Rated for up to 1,400 CFM at a maximum face velocity of 625 FPM, this filter suits forced-air systems where pressure drop management and filtration efficiency must both be addressed. Licensed HVAC technicians and facilities maintenance crews are the primary installers.

This filter fits any forced-air unit accepting a nominal 16 x 20 x 4 inch filter. Typical applications include residential gas or electric furnaces, air handlers, and split-system cooling equipment with 4-inch filter housings. The MERV 11 rating makes it suitable for environments where occupant health, dust control, or light allergen reduction is a priority without imposing the static pressure penalties of higher-MERV media. It is also appropriate for light commercial rooftop units and fan coil applications with compatible filter racks.

Key Features

• MERV 11 synthetic pleated media captures fine dust, pollen, mold spores, and pet dander
• Wire-backed pleat construction maintains media shape across the rated velocity range up to 625 FPM
• Beverage board frame with integrated design resists moisture-related deformation during normal HVAC operation
• Rated airflow of 1,400 CFM suits most residential and small commercial air handlers
• Low initial resistance of 0.13 inches w.g. at 375 FPM reduces blower load at typical operating velocities
• UL 900 listed for flammability compliance

Compatibility

Designed as a direct-fit replacement for any forced-air unit accepting a nominal 16 x 20 x 4 inch filter. Actual dimensions are 15.5 x 19.5 x 3.75 inches to allow standard filter-rack insertion.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified maintenance personnel. Always set the system thermostat to off and confirm the blower has stopped before removing the existing filter. Insert the replacement filter with the airflow arrow on the frame pointing toward the blower. Verify the filter seats flush in the rack with no bypass gaps around the frame perimeter before restoring system operation.
