The NORDIC PURE 15x23x1ExactCustomM8+C-6 is a custom-made, pleated MERV 8 Plus Carbon air filter built to exact dimensions for residential and light-commercial HVAC systems. Each filter ships as a pack of 6 and measures an actual 15 x 23 x 0.75 inches. The activated carbon layer targets odors alongside standard particulate filtration at the MERV 8 rating, making this a practical upgrade for households or job sites with airborne odor concerns. Licensed HVAC technicians and experienced DIYers install these filters in forced-air furnace and air conditioning systems where a non-standard opening size prevents use of a stock filter. The reinforced two-part frame supports consistent airflow and structural integrity throughout the filter service life.
This filter is designed for forced-air HVAC applications where the return-air grille or filter slot does not match a standard nominal size. The nominal size is 15 x 23 x 1, with an actual size of 15 x 23 x 0.75 inches. Because this is a custom product cut to exact measurements, it is essential to measure the existing filter or the filter slot with a tape measure before ordering. The actual width and length should match the listed dimensions to within 1/8 inch. Recommended replacement interval for 1-inch filters is every 30 to 90 days, depending on local air quality, occupancy, and system run time.
Designed as a custom OEM-style replacement for residential and light-commercial forced-air furnace and air conditioning systems requiring a 15 x 23 x 1 nominal filter opening where no standard-size filter provides an exact fit.
Installation is performed by a licensed HVAC technician or a qualified service professional. Power down the air handler or furnace at the disconnect or breaker before servicing the filter compartment. Confirm airflow direction arrow on the filter frame aligns with system airflow toward the blower. Because this is a custom-made product, verify exact slot measurements with a tape measure before installation to ensure a proper fit without gaps that would allow unfiltered air bypass.
