Aaf/flanders 10059.012025 Fiberglass Air Filter 20x25x1

Product Description

The AAF/FLANDERS 10059.012025 is a 20x25x1 inch spun fiberglass air filter rated MERV 1, designed to protect furnaces and central air conditioning systems from large airborne particulates. Built with self-retaining spun glass media and a heavy one-piece chipboard frame, this filter delivers a low initial pressure drop that reduces system strain and supports energy-efficient operation. It is UL Classified and carries a service life of up to 30 days under normal operating conditions. A designated space on the frame allows technicians to record the installation date for easy maintenance tracking. Each carton contains 24 filters.

This filter is suited for residential and light commercial forced-air HVAC applications, including gas furnaces and split-system central air conditioners. It is intended as a coarse-filtration pre-filter layer, catching large dust, lint, and debris before air reaches the heat exchanger or evaporator coil. The low-resistance fiberglass media is particularly well-suited for systems with lower static-pressure budgets or older equipment not designed for high-MERV media resistance. HVAC technicians and maintenance personnel typically stock these in bulk for scheduled filter change programs.

Key Features

• MERV 1 spun fiberglass media provides coarse particulate protection with minimal airflow restriction
• Low initial pressure drop supports energy efficiency and maintains rated system airflow
• Self-retaining media construction holds shape throughout the service interval
• Heavy one-piece chipboard frame for rigid, consistent fit in standard filter slots
• UL Classified construction
• Installation date field printed on frame for maintenance recordkeeping
• Sold 24 filters per carton for bulk stocking efficiency

Compatibility

Designed as a standard replacement fiberglass panel filter for residential and light commercial forced-air furnaces and central air conditioning systems using a 20x25x1 inch filter slot.

Installation Notes

Installation is performed by HVAC technicians or qualified maintenance personnel. Set the system thermostat to off and shut down power at the disconnect or breaker before removing the old filter. Install with the airflow arrow on the frame pointing toward the blower. Replace every 30 days or sooner in high-dust environments, and record the installation date on the frame at time of service.
