White Rodgers F825-0338 Prefilter

The White Rodgers F825-0338 Prefilter is a critical first-stage component designed specifically for the Emerson SST20 series electronic air cleaner. Measuring approximately 20-3/8" x 13" x 5/16", this washable aluminum mesh filter is engineered to capture large airborne particulates, including lint, hair, and heavy dust, before they reach the high-voltage ionizing wires and collecting cells. By maintaining a clean SST20 prefilter, technicians ensure optimal HVAC airflow and prevent premature loading of the electronic cells, which preserves the system's ability to maintain high-efficiency filtration without excessive pressure drop.

Constructed from high-grade multi-layer aluminum media, the F825-0338 is built to withstand repeated cleanings. For contractors servicing White Rodgers electronic air cleaners, it is worth noting that this 20x13 prefilter is compatible with models such as the SST2000-100, Emerson 20, and certain Grainger or Kenmore branded air cleaners. Regular maintenance involves soaking the element in a mild detergent solution or utilizing a dishwasher on a non-heat cycle to remove accumulated debris. Replacing damaged or warped prefilters is essential to prevent bypass air and maintain the integrity of the indoor air quality system.

• OEM Compatibility: Precision-fit for the White Rodgers SST20 series and SST2000-100 air cleaners to ensure no-gap filtration.
• System Protection: Arrests large debris to prevent arcing and snapping in the electronic collecting cells.
• Washable Design: Durable aluminum mesh construction allows for periodic cleaning, reducing long-term consumable costs for the end-user.
• Optimal Airflow: Engineered with a low initial resistance to maintain static pressure within factory specifications.
• Corrosion Resistance: Features a robust frame designed to hold up in high-humidity return air environments.

• How often should the F825-0338 prefilter be cleaned? In standard residential environments, the prefilter should be inspected and cleaned every 1 to 2 months. Systems in homes with pets or heavy dust may require more frequent maintenance to prevent airflow restriction.
• Can I run the SST20 unit without the prefilter? No. Operating the unit without the prefilter allows large particles to enter the ionizing section, which can cause constant arcing, damage the ionizing wires, and significantly decrease the efficiency of the electronic cells.
• Is this prefilter compatible with the SST14 or SST10 series? No, this part is specifically sized for the 20x13 SST20 cabinet. Please verify your cabinet dimensions and model number before ordering to ensure correct fitment.
