Nordic Pure 19x21x1ExactCustomM8-6 Merv 8 Furnace Filter 6pk

Product Description

The NORDIC PURE 19x21x1ExactCustomM8-6 is a custom-made MERV 8 pleated air filter designed for residential and light commercial AC and furnace systems. Rated at MERV 8 per ASHRAE standards, this filter captures 70 to 85 percent of airborne particles between 3 and 10 microns, including lint, dust, pollen, pet dander, and mold spores. The electrostatically charged filter media improves particle attraction without restricting airflow. The frame is constructed from heavy-duty, moisture-resistant beverage board. This pack includes 6 filters, each with a nominal size of 19x21x1 and an actual size of 19 x 21 x 0.75 inches. Installation is handled by HVAC technicians or knowledgeable homeowners as part of routine system maintenance.

This filter is suited for residential homes and light commercial spaces where indoor air quality is a priority. It is a strong choice for households with pets or allergy sufferers who require more frequent filter changes. Nordic Pure recommends replacing the filter every 1 to 3 months depending on the environment, with more frequent changes recommended in high-dust or high-dander settings. The custom sizing means the filter is cut or assembled to the exact dimensions listed, which may involve combining frames or using tape for structural integrity. This construction is functional and built to fit the stated dimensions precisely.

Compatibility

Designed as a custom exact-fit replacement filter for residential and light commercial HVAC systems requiring a 19x21x1 nominal filter size. Verify the actual opening dimensions of your filter slot before ordering, as this is a non-returnable custom-made product.

Installation Notes

Power down or set the HVAC system to off before removing the old filter to prevent unfiltered air from circulating during the swap. Confirm airflow direction arrows on the filter frame align with the direction of airflow in the system before seating the filter. Because this is a custom-cut product, handle with care during installation to avoid frame damage. Replace every 1 to 3 months, or more frequently in high-traffic, high-pet, or allergy-sensitive environments.
