The NORDIC PURE 20x27x1ExactCustomM13+C-6 is a custom-cut, pleated air filter rated MERV 13 with an integrated carbon layer, designed for residential and light-commercial HVAC systems including central air conditioners and gas or electric furnaces. Built from electrostatically charged synthetic media, the filter captures airborne particulates on each air pass while the carbon layer addresses odors. The actual dimensions are 20 inches by 27 inches by 0.75 inches, sized for a slot nominally listed as 20x27x1. This pack contains 6 filters. Licensed HVAC technicians and knowledgeable homeowners typically handle this replacement.
This filter is intended for forced-air HVAC systems that require a non-standard 20x27x1 slot. Because it is a custom-made product, it is cut to the exact dimensions listed and is not returnable. Nordic Pure recommends measuring the existing filter before ordering to confirm the opening accepts a 20 by 27 by 0.75 inch actual-size filter. The custom frame is built using a reinforced two-part construction and may include tape seaming depending on the final cut dimensions. Filter change intervals of 30 to 90 days are recommended depending on indoor and outdoor air quality conditions.
Designed as a custom exact-fit replacement for forced-air furnace and air conditioning filter slots with a nominal size of 20x27x1. Measure the existing filter opening before ordering, as this custom size is not eligible for returns.
Power down or set the thermostat to the off position before removing the existing filter. Note the airflow direction arrow printed on the filter frame and orient the replacement filter so the arrow points toward the blower. Slide the filter fully into the slot and confirm the frame seats flush with no bypass gaps around the edges. Custom-cut frames may include tape seams; do not separate the frame components.
