The NORDIC PURE 17x25x1ExactCustomM14-6 is a custom-cut, pleated AC furnace air filter rated MERV 14, sold in a 6-pack. It is designed to capture fine airborne particles including dust, pollen, pet dander, mold spores, smoke, bacteria, and virus carriers as air circulates through a residential or commercial HVAC system. The filter media is electrostatically charged to improve particle attraction and will not promote the growth of bacteria or mold on the filter surface. The frame is constructed from a heavy-duty, moisture-resistant beverage board. Actual dimensions are 17 x 25 x 0.75 inches, cut to exact size per order. HVAC technicians and building maintenance professionals install this filter in forced-air systems rated to handle MERV 14 filtration.
This filter is suited for residential and light commercial forced-air systems where high-efficiency filtration is required. MERV 14 performance is comparable to filters rated MPR 2800 on manufacturer-specific scales. Because MERV 14 filtration increases airflow resistance, it is intended for use only in HVAC systems rated to handle MERV 14 or higher, including newer high-efficiency systems designed for HEPA-grade filtration. Replacement is recommended every 1 to 3 months depending on occupancy, pet presence, and indoor air quality demands. This is a custom-made product cut to the exact nominal size specified in the part number and is not eligible for return.
Designed as an exact-cut replacement filter for forced-air HVAC systems with a filter slot accepting a nominal 17x25x1 filter. Verify actual opening dimensions before ordering. Compatible only with systems rated to handle MERV 14 or higher airflow restriction.
Installation is performed by HVAC technicians or qualified service personnel. Power down or set the thermostat to the off position before removing the existing filter to prevent unfiltered air from circulating through the system. Confirm airflow direction and install the filter with the arrow on the frame pointing toward the blower. Because this is a high-restriction MERV 14 filter, verify that the HVAC equipment is rated for MERV 14 or above before installation to avoid strain on the blower motor.
