Ao Smith FG16252N Fiberglass Air Filter 16x25x2 Case of 12

Product Description

The AO SMITH FG16252N is a fiberglass panel air filter sold in a case of 12 units, sized at 16 x 25 x 2 inches. It is engineered with progressively dense, small continuous fiberglass fibers that maximize dust-holding capacity across the filter media. An adhesive coating is applied to the fiber bed to prevent fiber migration into the air duct system. The chipboard and Monobond frame is heat-sealed to the media for added structural integrity. Licensed HVAC technicians and building maintenance staff typically stock and install these filters in residential and light commercial forced-air systems.

This filter is suited for standard forced-air HVAC applications where a low-cost, disposable fiberglass panel filter is specified. The loosely woven front layer captures larger dust and dirt particles first, while progressively denser layers toward the back trap finer particulate. The fiberglass scrim backing supports safe, clean handling during both installation and removal, reducing fiber release during service. Filters are packaged in a case of 12, making them practical for multi-unit residential properties, commercial facilities, or service contractors maintaining multiple systems.

Key Features

• Progressive-density fiberglass media captures large particles at the front and fine particles at the rear
• Adhesive applied to fiber bed prevents fiber migration into ductwork
• Fiberglass scrim backing allows safe, clean filter installation and removal
• Heat-sealed Monobond frame bonds media to frame for a tighter seal and reduced air bypass
• Chipboard frame construction encloses the media pad for structural support
• Sold as a case of 12 filters for contractor and facility stocking convenience

Compatibility

Designed as an OEM-style replacement panel filter for residential and light commercial forced-air HVAC systems accepting a 16 x 25 x 2 inch fiberglass filter.

Installation Notes

HVAC technicians or building maintenance personnel should power down the air handler or furnace at the disconnect before replacing filters. Confirm airflow direction arrow on the filter frame aligns with the direction of airflow toward the blower. Dispose of used fiberglass filters carefully to minimize airborne fiber exposure. Filter replacement intervals should follow the system manufacturer recommendations and site-specific dust load conditions.
