Glasfloss 20X25X4PL40 Pleated Air Filter 20x25x4 Merv 10

Product Description

The GLASFLOSS 20X25X4PL40 is a 4-inch deep pleated air filter from the Z-Line Series, designed for standard-capacity HVAC filtration applications. Measuring 20 x 25 x 4 inches and weighing 2.17 pounds, this filter delivers a MERV 10 rating per the ANSI/ASHRAE 52.2 test standard, capturing a broad range of airborne particulates including dust, pollen, mold spores, and pet dander. The filter media uses synthetic fibers that do not absorb moisture and will not support microbial growth, making it well-suited for environments where humidity is a concern. Licensed HVAC technicians and building maintenance professionals are the typical installers for this filter type.

The Z-Line Series pleated filter is appropriate for a wide range of residential and light commercial HVAC systems where a 20 x 25 x 4 inch filter slot is present. It fits standard return-air filter housings, media cabinets, and whole-house filtration systems. The Z-Line line includes the SB, ZL, and HV model variants at MERV 10, providing improved particulate capture over standard 1-inch panel filters without significantly increasing static pressure drop across the air handler or furnace blower system.
