Nordic Pure 8_3/4x18x1ExactCustomM7+C-6 Furnace Filter 6pk

Product Description

The NORDIC PURE 8_3/4x18x1ExactCustomM7+C-6 is a custom-cut, pleated MERV 7 plus carbon air filter designed for residential and light commercial AC and furnace systems. Measuring an exact 8.75 x 18 x 0.75 inches, this filter is hand-fabricated to precise dimensions and includes an activated carbon layer that targets odors alongside standard particulate filtration. The MERV 7 rating means the filter captures 50 to 70 percent of airborne particles in the 3 to 10 micron range, including lint, dust, pollen, pet dander, and mold spores. Sold in a 6-pack, these filters are made in the USA and feature a reinforced two-part frame for added structural durability.

This filter is intended for residential and light commercial HVAC applications where a non-standard filter opening requires a custom-dimensioned replacement. It fits air handler returns, furnace filter slots, and inline filter cabinets that cannot accommodate standard nominal sizes. The combination of MERV 7 mechanical filtration and a carbon media layer makes it suitable for spaces with elevated dust loads or mild odor concerns. Recommended change interval for 1-inch filters is every 30 to 90 days depending on environmental conditions. Because this product is custom-fabricated to the exact dimensions listed, it is not returnable.

Compatibility

Designed as a custom-dimensioned replacement for residential and light commercial AC and gas furnace systems requiring an exact filter size of 8.75 x 18 x 0.75 inches. Measure the existing filter carefully before ordering, as this item is fabricated to the specific dimensions listed and is not eligible for return.

Installation Notes

Filter installation is typically performed by the homeowner, facility maintenance staff, or a licensed HVAC technician. Power down the air handler or furnace at the disconnect or thermostat before removing the existing filter to prevent unfiltered air from being drawn through the system. Confirm airflow direction arrows on the filter frame align with the direction of air movement toward the blower. Because actual filter dimensions are 8.75 x 18 x 0.75 inches, verify the filter slot measurement with a tape measure before ordering to ensure a proper fit.
