Glasfloss 20X30X1PL40 Z-line Pleated Air Filter 20x30x1

Product Description

The GLASFLOSS 20X30X1PL40 is a Z-Line Series standard-capacity pleated air filter sized at 20 x 30 x 1 inches and rated MERV 10 per the ANSI/ASHRAE 52.2 test standard. It is designed for use in residential and light commercial HVAC air handling systems where improved particulate capture over standard fiberglass panels is required. The filter media uses synthetic fibers that do not absorb moisture and will not support microbial growth, making it a reliable choice in humid climates or systems prone to condensation. HVAC technicians and service professionals install this filter during routine maintenance or system changeouts.

The Z-Line pleated filter fits standard 20 x 30 x 1 inch filter slots found in forced-air furnaces, air handlers, and return-air grille housings. It is suited for both residential and light commercial applications where a MERV 10 rating is specified. The pleated design increases media surface area compared to flat-panel filters, supporting adequate airflow while capturing dust, pollen, mold spores, and similar particles. This filter is part of the broader Z-Line Series, which includes the SB, ZL, and HV filter variants, all achieving MERV 10 ratings under the same test standard.
