Nordic Pure 13x21.5x1CM10-4 Merv 10 Air Filter 4 Pack

Product Description

The NORDIC PURE 13x21.5x1CM10-4 is a MERV 10 pleated air filter sold in a 4-pack, sized at a nominal 13x21.5x1 inches with an actual dimension of 13 x 21.5 x 0.75 inches. It is designed as a replacement filter for residential and light commercial HVAC systems, including furnaces and central air conditioners. The filter media is electrostatically charged and treated with an antimicrobial agent to capture airborne particulates including pollen, pet dander, dust mites, mold spores, smoke particles, bacteria, virus carriers, and allergens. The heavy-duty beverage board frame is moisture resistant for durability in high-humidity air streams. Licensed HVAC technicians and building maintenance staff typically install and service these filters during routine preventive maintenance.

This filter is intended for standard 1-inch filter slots in residential and light commercial HVAC systems. It is positioned as a direct replacement for Carrier-compatible filter applications requiring a 13x21.5x1 nominal size. The MERV 10 efficiency rating is equivalent to MPR 1000 on the 3M Filtrete scale, making it appropriate for environments where occupants have mild allergy concerns or where moderate particulate control is required. Typical replacement intervals range from one to three months depending on occupancy, pet presence, and indoor air quality conditions.

Installation Notes

Filter replacement is a standard HVAC maintenance task performed by licensed HVAC technicians or qualified building maintenance personnel. Before replacing the filter, set the system to off at the thermostat to prevent unfiltered air from being drawn through the unit during the swap. Confirm airflow direction marked on the filter frame aligns with system airflow before seating the filter in the rack. Follow local codes and equipment manufacturer guidelines for recommended replacement intervals.
