The NORDIC PURE 13x20x1ExactCustomM8+C-6 is a custom-cut, pleated MERV 8 air filter with activated carbon, sized at an exact 13 x 20 x 0.75 inches actual and sold in a 6-pack. Constructed from electrostatically charged synthetic media, it captures airborne particulates including lint, dust, pollen, pet dander, mold spores, and odor-causing contaminants. The carbon layer adds an additional stage of odor reduction beyond standard MERV 8 filtration. This filter is made to exact dimensions by cutting down or combining standard filter frames, resulting in a unit built to fit non-standard filter slots without modification. HVAC technicians and facilities maintenance professionals are the primary installers.
This filter is suited for residential and light commercial HVAC systems where a non-standard slot size prevents the use of off-the-shelf filters. The exact 13 x 20 x 0.75 inch actual size makes it appropriate for systems where a nominally sized filter would leave gaps. The electrostatically charged media supports low airflow resistance, reducing strain on blower motors and maintaining system efficiency across the filter service interval. Nordic Pure recommends replacement every 30 to 90 days depending on environmental conditions and particulate load.
Designed as a custom exact-size replacement filter for HVAC systems requiring a 13 x 20 x 0.75 inch actual filter slot. This is a non-standard custom size; measure the existing filter slot carefully before ordering, as this product is not eligible for return.
Installation is typically performed by HVAC technicians or facilities maintenance personnel. Power down or set the thermostat to off before opening the filter compartment to prevent unfiltered air from being drawn into the system during changeout. Confirm airflow direction arrows on the filter frame align with the direction of airflow toward the blower before seating the filter. Because this is a custom exact-size filter, verify the actual slot dimensions with a tape measure prior to ordering, as returns are not accepted on custom-made sizes.
