Nordic Pure 19_1/2x21x1ExactCustomM13+C-6 Furnace Filter

Product Description

The NORDIC PURE 19_1/2x21x1ExactCustomM13+C-6 is a custom-cut, pleated MERV 13 plus carbon air filter designed for residential and light-commercial HVAC systems. Supplied in a 6-pack, each filter measures 19.5 x 21 x 0.75 inches actual size and combines a high-efficiency filter media with an activated carbon layer to capture particulates and reduce common household odors. The MERV 13 rating means the media captures over 90% of airborne particles between 1 and 10 microns and 50% to 70% of particles between 0.3 and 1 micron. HVAC technicians and homeowners install these filters in forced-air furnaces and central air conditioning systems where a non-standard opening requires an exact-dimension filter rather than a stock size.

This filter is built for HVAC applications where the filter slot does not match any standard nominal size. Nordic Pure manufactures each unit to the dimensions listed by cutting down or combining standard filter frames, using reinforced frame construction with a 2-part border for added rigidity and balanced airflow. Recommended replacement intervals are every 30 to 90 days for 1-inch filters, though actual service life depends on local air quality and system runtime. Because these are made to order, confirm your actual opening dimensions with a tape measure before purchasing. The actual width and length of your existing filter should fall within 0.125 inches of the ordered size.

Compatibility

Designed as a custom exact-size replacement for residential and light-commercial forced-air furnace and central AC systems with a filter opening requiring an actual filter dimension of 19.5 x 21 x 0.75 inches. Verify your current filter slot measurement before ordering, as custom-made filters are not eligible for return.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified homeowners servicing forced-air systems. Always switch the system to the off position at the thermostat and shut down power at the disconnect or breaker before removing the old filter. Confirm airflow direction and align the filter so the directional arrow on the frame matches the direction of airflow toward the blower. Because this is a custom-cut filter, do not attempt to trim or modify the unit after receipt.
