Nordyne 918737 HEPA Filter

The Nordyne 918737 HEPA filter is a high-efficiency media solution engineered for critical residential and commercial indoor air quality applications. Maintaining a nominal size of 20x22x5 (actual dimensions 19.75" x 22" x 5.25"), this genuine OEM replacement is rated at MERV 11, specifically designed to protect blower motors and heat exchangers from particle bypass. The Nordyne 918737 utilizes professional-grade HEPA filtration technology to capture 99.97% of airborne contaminants as small as 0.3 microns, including fine dust, metallic particles, and microorganisms. Using this HVAC replacement filter ensures optimal static pressure across the evaporator coil, preventing premature equipment failure while maintaining airflow velocity of up to 2000 CFM. For contractors Servicing Nortek Global HVAC units, this whole-house air cleaner filter provides a precise fit for cabinets requiring the MAH-1056B or 918737 specification, ensuring a sealed system that prevents unfiltered air leakage.

Key Benefits for HVAC Professionals

• MERV 11 High-Efficiency: Provides a professional-grade barrier against sub-micron particles without causing excessive pressure drop.
• OEM Compatibility: Exact replacement for Nordyne 918737 and MAH-1056B, ensuring fit and seal in dedicated air cleaners.
• System Longevity: Captures debris that would otherwise accumulate on sensitive HVAC components, reducing service call frequency.
• Industrial-Scale Capacity: Rated for high-airflow systems (up to 2000 CFM), making it suitable for larger residential and light commercial air handlers.

Common Questions about the Nordyne 918737 What is the difference between the nominal and actual size for this filter? The nominal size is labeled as 20" x 22" x 5", but the actual technician measurements are 19.75" x 22" x 5.25". Always verify the cabinet rail width before installation to ensure a friction-tight fit. Can I swap this for a standard MERV 8 pleated filter? While a lower MERV rating may reduce static pressure, the Nordyne 918737 is critical for systems designed specifically for HEPA-level filtration. Reducing filtration quality can lead to coil fouling and decreased indoor air quality. How often should this HVAC media filter be replaced? Under standard operating conditions, the service cycle is 6 to 12 months. However, in environments with high particulate loads or heavy construction, contractors should monitor the pressure drop to determine the precise replacement interval.
