Nordic Pure 21.5x23.5x1CM8-6 Merv 8 Air Filter 6 Pack

Product Description

The NORDIC PURE 21.5x23.5x1CM8-6 is a 6-pack of MERV 8 pleated AC and furnace air filters sized at 21.5 x 23.5 x 0.75 inches actual dimensions. These filters use electrostatically charged, hypoallergenic, and antimicrobial filter media housed in a moisture-resistant beverage board frame. Rated at MERV 8, equivalent to MPR 800, they capture lint, dust, pollen, pet dander, dust mites, mold spores, and bacteria on each air pass. Manufactured in the USA, these filters are designed for residential and light commercial HVAC systems where consistent indoor air quality and equipment protection are priorities.

These filters are suited for residential furnaces, central air conditioning systems, and air handlers where a nominal 21.5 x 23.5 x 1 inch filter slot is specified. They serve as a direct Carrier replacement in compatible systems and are appropriate for homes with pets, allergy sufferers, or environments with elevated particulate loads. HVAC technicians, property maintenance staff, and knowledgeable homeowners typically handle installation. Replacement every 1 to 3 months is recommended, with more frequent changes advised in high-dust or high-dander environments.

Compatibility

Designed as a Carrier replacement air filter for HVAC systems requiring a nominal 21.5 x 23.5 x 1 inch filter. Confirm the actual filter slot dimensions match the actual size of 21.5 x 23.5 x 0.75 inches before installation, as nominal and actual sizes differ on nearly all air filters.

Installation Notes

Always shut down the furnace or air handler at the thermostat and disconnect power at the disconnect switch or breaker before removing or installing the filter. Note the airflow direction arrow printed on the filter frame and orient it toward the blower, not toward the return duct. Check the filter slot dimensions against the actual filter size, not the nominal size, to confirm proper fit. Filters should be inspected monthly and replaced on a schedule appropriate to the site conditions.
