Airex TA16251 Fiberglass Panel Air Filter 16x25x1

Product Description

The AIREX TA16251 is a 16 x 25 x 1 inch disposable fiberglass panel air filter designed for residential and light commercial HVAC and air conditioning applications. It uses Polystrand fiberglass media, a continuous-strand fiberglass that measures greater than 3.5 microns in diameter, which classifies the fibers as nonrespirable. The media is loosely spun on the air-entering side and progressively woven tighter toward the air-exiting side, creating a graduated density structure with a heavy laminated backing. This design increases dust holding capacity and reduces surface loading. The filter is rated for airflow between 850 and 1350 CFM and carries a MER Value of 4 to 5.

This filter is sized at 16 x 25 x 1 inches and fits standard filter slots in forced-air systems, including central air conditioning units and gas or electric furnaces with compatible filter housings. It is suited for high-volume replacement programs in residential settings and light commercial environments where a cost-effective, disposable fiberglass filter is appropriate. The heavy-duty moisture-resistant white kraft board frame holds its shape in humid conditions commonly encountered inside air handler cabinets. HVAC technicians and service contractors routinely stock this size for scheduled maintenance calls.

Key Features

• Polystrand fiberglass media with fibers greater than 3.5 microns, classified as nonrespirable
• Graduated media density: loose on the air-entering side, progressively tighter toward the air-exiting side for depth filtration
• Dust holding capacity of 148 grams reduces change-out frequency under normal loading conditions
• Rated airflow of 850 to 1350 CFM covers a wide range of residential and light commercial air handlers
• Temperature rated to 180 degrees F continuous and 200 degrees F intermittent
• Heavy-duty moisture-resistant white kraft board frame resists deformation inside humid air handler cabinets
• UL applicable standard compliance for added assurance in commercial installations

Compatibility

Designed as a direct-fit disposable panel filter for air conditioning units and forced-air HVAC systems requiring a 16 x 25 x 1 inch filter slot.

Installation Notes

Installation should be performed by a qualified HVAC technician or trained service professional. Power down the air handling unit or furnace at the disconnect or breaker before removing the existing filter. Confirm airflow direction arrows on the filter frame align with the direction of airflow into the unit before seating the filter. Disposable fiberglass filters should not be vacuumed, washed, or reinstalled after removal.
