Nordic Pure 20x20x5HM14+C-4 Merv 14 Carbon Furnace Filter 4 Pack

Product Description

The NORDIC PURE 20x20x5HM14+C-4 is a MERV 14 pleated furnace filter with activated carbon, designed for high-performance residential air filtration in forced-air heating and cooling systems. The nominal size is 20x20x5 inches with an actual size of 19.63 x 19.88 x 4.38 inches - a measurement difference that matters at installation. The filter media is electrostatically charged synthetic material paired with a flat activated carbon panel that captures airborne particulates and adsorbs odorous gases and volatile organic compounds. Licensed HVAC technicians and service professionals install this filter in deep-media filter housings that accept the 4.38-inch actual depth. This listing includes 4 filters per box.

This filter fits residential and light-commercial forced-air systems that use a deep-media housing requiring a nominal 20x20x5 filter with a 4 3/8-inch actual depth. It is cited as a replacement for Honeywell, Lennox, Carrier, and Bryant systems that use this housing size. Because nominal-to-actual depth varies by manufacturer and housing design, always measure the existing filter or housing before ordering. The MERV 14 rating makes it suitable for applications where fine particulate control and odor reduction are priorities, such as homes with pets, allergy sensitivities, or recent renovation work.

Compatibility

Cited as a replacement for Honeywell, Lennox, Carrier, and Bryant systems that use a nominal 20x20x5 housing with a 4 3/8-inch actual depth. Replaces Honeywell 20x20x4 filters where the actual depth is 4 3/8 inches. Always verify actual filter dimensions against housing dimensions before installation - nominal sizing varies by manufacturer.

Installation Notes

Installation is performed by a licensed HVAC technician or a qualified service professional. Power down the air handler or furnace at the disconnect before replacing the filter. Confirm the housing accepts the 4.38-inch actual depth before inserting the filter, and ensure airflow direction arrows on the frame align with system airflow direction. Nordic Pure recommends replacing this filter every 3 to 6 months, or more frequently in high-dust or renovation environments.
