Nordic Pure 14x18x1ExactCustomM8+C-6 Merv 8 Carbon Filter

Product Description

The NORDIC PURE 14x18x1ExactCustomM8+C-6 is a custom-cut, pleated AC and furnace air filter rated MERV 8 with an activated carbon layer. It is built from electrostatically charged synthetic media that captures airborne particulates while the carbon component helps reduce common household odors. The actual dimensions are 14 x 18 x 0.75 inches, built to fit the exact opening without the typical nominal undercut. Sold in a 6-pack, this filter suits residential and light-commercial HVAC systems where both particulate control and odor reduction are priorities. Licensed HVAC technicians and experienced DIYers install this filter during routine maintenance cycles.

This filter is designed for forced-air heating and cooling systems that require an exact custom size rather than a standard nominal fit. The 14 x 18 x 0.75-inch actual size is intended for return-air grilles or filter cabinets that cannot accommodate a standard nominal filter without gaps. Typical applications include residential gas furnaces, electric air handlers, and split-system AC units where a precise fit is necessary to prevent air bypass. The 6-pack format supports a full seasonal maintenance schedule at a 30-to-90-day replacement interval.

Key Features

• MERV 8 rating captures 70-85% of airborne particles between 3 and 10 microns, including lint, dust, pollen, pet dander, and mold spores
• Activated carbon layer reduces common household odors passing through the filter media
• Electrostatically charged synthetic media attracts and holds particulates without restricting airflow
• Reinforced 2-part frame construction provides added rigidity and consistent shape retention over the filter life
• Exact custom cut to 14 x 18 x 0.75 inches actual size, eliminating air bypass gaps common with nominal-size filters
• Made in the USA

Compatibility

Custom-made to exact dimensions for forced-air HVAC systems requiring a 14 x 18 x 0.75-inch actual filter size. This is a non-returnable custom product; verify the actual measured size of the existing filter before ordering.

Installation Notes

Power down the HVAC system at the thermostat or disconnect before replacing the 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 with a tape measure before installation to confirm fit. Replace every 30 to 90 days depending on indoor air quality conditions and system runtime.
