Nordic Pure 17x21x1ExactCustomM7+C-12 Merv 7 Filter 12pk

Product Description

The NORDIC PURE 17x21x1ExactCustomM7+C-12 is a custom-cut, pleated air filter rated MERV 7 with an integrated carbon layer, designed for residential and light-commercial HVAC systems. Built from electrostatically charged synthetic media, it captures airborne particulates in the 3-10 micron range at a 50-70 percent efficiency rate while the carbon component addresses common household odors. The nominal size is 17x21x1, with an actual size of 17 x 21 x 0.75 inches. This filter ships as a 12-pack and is installed by homeowners, property managers, and HVAC technicians servicing split systems, air handlers, and forced-air furnaces.

This filter is suited for residential homes and office environments where both particulate capture and odor control are priorities. The MERV 7 rating makes it effective against lint, household dust, pollen, dust mites, pet dander, baking flour, and mold spores without creating excessive static pressure drop across the system. The carbon layer targets common odors that standard pleated media does not address. Because this is a custom-made exact-size filter, it is manufactured to the precise dimensions listed and is not eligible for returns. Filter life varies by environment; typical replacement intervals run every 30 to 90 days.

Compatibility

Designed as an exact-size replacement filter for residential and light-commercial forced-air furnaces and air handlers requiring a 17x21x1 custom filter size. Verify actual filter slot dimensions before ordering, as this custom size is not eligible for returns.

Installation Notes

Always power down the HVAC system at the thermostat and disconnect power before removing or inserting a filter. Confirm airflow direction arrows on the filter frame align with the direction of airflow toward the blower. Because this is a custom exact-size filter, measure the existing filter opening carefully before installation to confirm proper fit. Replace the filter every 30 to 90 days depending on environmental conditions such as pets, construction dust, or high pollen seasons.
