Nordic Pure 12x24x4PM12C-2 Merv 12 Carbon Air Filter 2 Pack

Product Description

The NORDIC PURE 12x24x4PM12C-2 is a MERV 12 pleated plus carbon air filter designed for residential and light-commercial HVAC systems. It combines a MERV 12-rated filtration layer fused with an activated carbon layer, capturing fine particulates while adsorbing odorous gases and volatile organic compounds (VOCs). The dual-material construction delivers 33% more surface area than a single-layer pleated filter, reducing flow restriction while maintaining filtration efficiency. The filter captures more than 90% of 3.0-10.0 micron contaminants and up to 90% of 1.0-3.0 micron contaminants. It is sold in a 2-pack and suited for installation by HVAC technicians or knowledgeable homeowners.

This filter is intended for use in forced-air furnaces and central air conditioning systems requiring a 12x24x4 nominal filter size. The actual installed dimensions are 11.5 x 23.38 x 3.63 inches, which is standard for this nominal slot size. It is well-suited for environments with elevated odor concerns, allergy sensitivities, or high particulate loads such as homes with pets, smokers, or ongoing renovation activity. The MERV 12 rating is comparable to MPR 1500-1900 filters. Filter replacement every 3 to 6 months is recommended to maintain system airflow and filtration performance.

Key Features

• MERV 12 filtration captures lint, household dust, pollen, dust mites, pet dander, smoke particles, virus carriers, bacteria, and mold spores
• Activated carbon layer adsorbs VOCs, odors, and gases without significantly restricting airflow
• Hypoallergenic, antimicrobial, and electrostatic filter media inhibits bacteria and mold growth
• Heavy-duty moisture-resistant beverage board frame with bonded metal mesh pleat support grid
• 33% more surface area compared to standard single-layer pleated filters
• Made in the USA

Compatibility

Designed as an OEM-style replacement filter for residential and light-commercial forced-air furnaces and central air conditioning systems requiring a nominal 12x24x4 inch filter slot. Actual size is 11.5 x 23.38 x 3.63 inches. Verify the actual filter slot dimensions before installation to confirm fit.

Installation Notes

Air filters in this size class are typically installed by HVAC technicians or trained service personnel, though knowledgeable homeowners can perform the replacement. Power down or set the thermostat to the off position before opening the filter compartment to avoid drawing an unfiltered air stream through the blower. Confirm airflow direction arrow on the filter frame aligns with system airflow toward the blower. Do not operate the system without a filter installed, as unfiltered air can foul the heat exchanger, evaporator coil, and blower assembly.
