Airex TA12241 Fiberglass Panel Air Filter 12x24x1 in

Product Description

The AIREX TA12241 is a 12 x 24 x 1 inch disposable fiberglass panel air filter designed for residential and light commercial HVAC and air conditioning applications. It uses Polystrand fiberglass media encapsulated in a proprietary polymer process that produces a high-loft, graduated-density filtration layer. Fibers are loosely arranged on the air-entering side and progressively woven tighter toward the air-exiting side, creating a laminated backing that increases dust-holding capacity and resists surface loading. The filter achieves a MERV-equivalent rating of 4 to 5 and handles airflow rates between 600 and 1000 CFM. A heavy-duty moisture-resistant white kraft board frame holds the media securely in place.

This filter suits standard forced-air systems, central air conditioning units, and return-air grille applications where a 12 x 24 x 1 inch nominal size is specified. The graduated media construction extends service life by capturing particulates progressively through the filter depth rather than at the surface alone. The disposable design simplifies changeout during routine maintenance cycles, making it a practical choice for HVAC technicians servicing residential and light commercial equipment on scheduled service agreements.

Key Features

• Polystrand fiberglass media encapsulated in polymer for safe, non-respirable fiber construction — continuous strand diameter exceeds 3.5 microns
• Graduated media density: loosely spun on the inlet face, progressively tighter toward the outlet face for improved dust-holding and reduced surface loading
• Dust holding capacity of 105 grams extends filter service intervals
• Rated for continuous operation up to 180 degrees F and intermittent exposure up to 200 degrees F
• Flow rate range of 600 to 1000 CFM with a resistance of 0.5 PA
• Heavy-duty moisture-resistant white kraft board frame — no metal backing required
• UL applicable standard; disposable design for straightforward replacement

Compatibility

Designed as an OEM-style replacement panel filter for residential and light commercial air conditioning and forced-air HVAC systems requiring a 12 x 24 x 1 inch disposable fiberglass filter.

Installation Notes

Installation is typically performed by HVAC technicians or qualified service personnel. Always shut down the air handler or furnace at the disconnect or thermostat before removing or installing the filter. Confirm airflow direction markings on the frame align with the system airflow arrow before seating the filter. Dispose of used filters in accordance with local waste disposal requirements.
