Product Description.

Glasfloss 13x20x1 Z-Line MERV 10 Furnace Air Filters

Extended Surface Pleated Media, Rugged Design, Low Pressure Drop, High Energy Efficient.

The Glasfloss 13x20x1 Z-Line Pleated  Air Filters offers superior performance with MERV 10 rating (Minimum Efficiency Rating Value). Due to the higher MERV 10 rating value, it holds more Micro Dust Particles, Lint, Mold, Pollen, Debris, Dust Mites & Bacteria compare to MERV 8 filters available in the market.

FILTER MEDIA: 100% Synthetic Non-Woven Fibers made by Kimberly-Clarke USA offers higher MERV rating, low resistance to air flow, high holding dust capacity and does not absorb moisture and resists microbial growth.

PROVEN TEST RESULTS: ALL the Glasfloss Air Filters are rigorously tested by third party under ANSI/ASHRAE 52.2 test procedures for MERV rating value 10. The Glasfloss Air Filters are classified per UL Standard 900 for flammability requirement and maximum operating temperature limit is 180⁰F (82⁰C).

EFFICIENT V-PLEATS DESIGN: The Glasfloss 13x20x1 V-Pleats design increase the surface area of contact with Air Flow hence collect maximum Micro Dust Particles, Lint, Molds, Bacteria, Pollen and Debris. It offers less resistance to air flow which save in energy cost and increases AC unit life. 

FILTER MEDIA SUPPORT/FRAME:  A heavy duty, galvanized, recycled expanded metal reinforcement which is laminated to the air exit side of the media by Thermosetting Adhesive to maintain the structural integrity of the radial pleats. An eco-friendly, two-piece, moisture media to avoid air leakage from filter assembly.

APPLICATIONS: The Glasfloss 13x20x1 Z-Line MERV 10 Furnace Air Filters are excellent choice for Residential Homes, Commercial Buildings, Hospitals, School/Universities, Data Centers, Laboratories and many industrial applications for pre-filter use.
