Honeywell Filters 20x25x4 MERV 11 MERV 12 | 20X25X5

Precision Engineering and Detailed Compatibility

• Seamless Honeywell & Lennox Replacement: This Nordic Pure 20x25x5 air filter Honeywell compatible design is a precision-engineered fit for model numbers FC100A1037, FC200E1037, 203720, f25f1026, and F1026. It also serves as a high-impact replacement for Lennox X6673 and X6675 units manufactured prior to 2013. With an actual depth of 4 3/8 inches, it ensures a tight, professional-grade seal that prevents air bypass, ensuring every cubic foot of air is scrubbed clean.
• Universal Cross-Reference Authority: Effortlessly upgrade your current 20x25x4 Filtrete DP03DC (UPC 051111024454 or 5111102445), Precisionaire #82655.0452025, or Air Demon 14. Choosing Nordic Pure means slashing utility costs and extending the lifespan of your equipment. By keeping your heating and cooling coils pristine, you allow for maximum heat transfer and efficiency, preventing the dirty sock syndrome and expensive emergency repairs.
• Industrial Strength American Construction: Every Nordic Pure filter is proudly manufactured in the USA using a heavy-duty, moisture-resistant beverage board frame. This robust housing is reinforced with a metal mesh support grid bonded to the pleats, ensuring the filter remains rigid and effective even under high-velocity air pressure without bowing or buckling.
• Advanced Electrostatic Protection: The Nordic Pure electrostatic charged fibers act like a magnet for airborne contaminants. This specialized media naturally inhibits the growth of mold and bacteria on the filter itself, resulting in a healthier, fresher living environment that helps reduce allergy symptoms and promotes better respiratory health for your loved ones.
