Nordic Pure 20x24x4M7+C-2 Merv 7 Plus Carbon Air Filter 2 Pack

Product Description

The NORDIC PURE 20x24x4M7+C-2 is a MERV 7 pleated air filter with activated carbon, sold in a 2-pack, designed for residential forced-air HVAC systems including central air conditioners and gas or electric furnaces. The electrostatically charged synthetic media captures airborne particulates as small as 3.0 to 10.0 microns, while a flat-panel activated carbon layer adsorbs odorous gases and volatile organic compounds (VOCs). The heavy-duty beverage board frame is moisture resistant, and a bonded metal mesh support grid prevents pleat collapse under airflow. The antimicrobial, hypoallergenic media inhibits bacterial and mold growth on the filter surface. Nominal size is 20x24x4 with an actual size of 19.38 x 23.38 x 3.63 inches.

This filter is suited for residential homes and light commercial settings where odor control alongside particulate capture is a priority. Common install scenarios include central ducted systems with 4-inch filter slots, whole-house air handlers, and gas furnaces requiring a high-capacity filter with extended service intervals. The carbon layer makes it well suited for households with pets, cooking odors, or VOC-generating finishes and adhesives. NORDIC PURE rates this filter as equivalent to MPR 600, giving technicians and homeowners a familiar reference point when cross-referencing filter performance ratings.

Key Features

• MERV 7 electrostatically charged synthetic media captures particles 3.0 to 10.0 microns including pollen, dust mites, pet dander, mold spores, and household dust
• Activated carbon flat-panel layer adsorbs odorous gases and VOCs to reduce unwanted smells
• Hypoallergenic, antimicrobial media inhibits bacterial and mold growth on filter surface
• Moisture-resistant beverage board frame with bonded metal mesh pleat support for structural integrity
• Equivalent to MPR 600 for cross-reference with other filter rating systems
• Made in the USA; 2-pack configuration reduces per-filter cost and extends supply between service calls

Compatibility

Designed as a direct-fit replacement for residential and light commercial forced-air systems with a 20x24x4 nominal filter slot. Actual dimensions are 19.38 x 23.38 x 3.63 inches; verify the filter cavity measurement against actual size before installation, as nominal and actual dimensions differ across HVAC equipment brands.

Installation Notes

Filter installation in forced-air systems is typically performed by HVAC technicians or knowledgeable building occupants; always set the system thermostat to off before replacing the filter. Confirm airflow direction by matching the arrow printed on the filter frame to the direction of airflow toward the blower. NORDIC PURE recommends replacing this filter every 3 to 6 months depending on indoor air quality conditions, occupancy, and the presence of pets or ongoing renovation activity. Do not attempt to wash or reuse this filter; it is a disposable unit.
