White-Rodgers F825-0432 Prefilter

The White-Rodgers F825-0432 Prefilter is a critical field-service component designed for the SST14 Electronic Air Cleaner series. Measuring exactly 13x16x1/4 inches, this genuine OEM part utilizes a multi-layered aluminum mesh to capture large airborne particulates before they reach the primary ionizing cells. In the field, ensuring a clean prefilter is essential for maintaining the high-voltage efficiency of the collection plates and preventing premature arcing. This mesh is constructed from expanded aluminum of varying densities, providing a low-pressure drop while effectively shielding the internal components from heavy dust loading.

For a correct tech-spec fit, the F825-0432 is the designated replacement for White-Rodgers SST1400 systems and is fully compatible with models including the 14C26S-010 and 14C27S-010. Technicians should verify the 13x16 nominal sizing during routine HVAC filter replacement to ensure the gasketed seal remains tight within the cabinet. Regular washing of this aluminum mesh filter is recommended every 60-90 days using a mild detergent or specialized filter cleaner to restore the electrostatic capture capability of the electronic air cleaner system.

• Precision Fit: Exactly sized at 13x16x1/4 for seamless integration into the White-Rodgers SST14 frame.
• Durable Construction: Heavy-duty aluminum mesh design handles routine high-pressure washing without degradation.
• System Protection: Captures large debris to prevent damage to expensive ionizing wires and internal collection cells.
• Optimal Airflow: Engineered for minimal static pressure resistance, supporting the 1400 CFM rating of the SST series.

• Is the White-Rodgers F825-0432 washable? Yes, this is a permanent washable HVAC filter that can be cleaned with water and a non-corrosive degreaser.
• How many prefilters does the SST1400 require? Most SST14 and SST1400 configurations utilize a pair of these filters to cover the full intake surface.
• Can I use a different size filter? No, using anything other than the 13x16x1/4 dimensions will lead to "blow-by," allowing dirt to bypass the filtration system.
