Nordyne 918396 Filter

For heavy-duty applications in high-efficiency media air cleaners, the Nordyne 918396 Filter is a professional-grade solution engineered to maintain system integrity. This 20x20x5 furnace filter provides a MERV 11 rating, delivering superior capture of micro-particles such as dust, pollen, and pet dander without creating excessive static pressure. With an actual size of 20 1/4" x 20 3/4" x 5 1/4", it ensures a tight seal within the cabinet, preventing air bypass that can lead to evaporator coil fouling. Designed for use in Nordyne model 918377 and N-MU2020 media cleaners, it serves as a direct cross-reference for parts FS2020, M2-1056, and MU2020. This deep-pleated replacement filter offers significant surface area for high dust-holding capacity, extending the service interval compared to standard 1-inch filters. Using a genuine Nordyne OEM filter or high-spec equivalent maintains the energy efficiency of your air handler or furnace by ensuring the blower motor operates within its designed CFM parameters.

• High CADR Performance: The MERV 11 filtration media effectively traps 95% of airborne contaminants, protecting downstream components and improving indoor air quality.
• Precision Fitment: Designed specifically for Nordyne furnace filter cabinets to prevent unfiltered air from bypassing the media through gaps.
• Optimized Static Pressure: The deep 5-inch pleat configuration maximizes airflow while minimizing resistance, reducing wear on the blower motor.
• Industrial-Grade Construction: Features a moisture-resistant frame and reinforced wire backing to prevent media collapse during high-velocity cooling cycles.
