Nordic Pure 16_1/2x21x1ExactCustomM13+C-6 Furnace Filter

Product Description

The NORDIC PURE 16_1/2x21x1ExactCustomM13+C-6 is a custom-cut, MERV 13 plus carbon pleated air filter designed for residential and light-commercial AC and furnace systems. Built to exact dimensions of 16.5 x 21 x 0.75 inches, this filter combines a high-efficiency MERV 13 filtration media with an activated carbon layer to capture fine particulates and reduce odors simultaneously. It is sold in a pack of six and is manufactured to order based on the dimensions specified at purchase. Licensed HVAC technicians and experienced DIYers install this filter in forced-air systems where a non-standard opening requires a custom-sized media filter.

This filter is suited for residential forced-air furnaces and central air conditioning systems with non-standard filter openings that cannot accept a stock-size replacement. The actual dimensions are 16.5 x 21 x 0.75 inches, making it appropriate for applications where the rough opening measures approximately 16.5 x 21 inches in width and length and accepts a 1-inch nominal depth filter slot. Because this is a custom-made product cut to the exact size specified at order, installers should verify the actual opening measurement with a tape measure before purchasing. The nominal size is listed as 16-1/2 x 21 x 1.

Key Features

• MERV 13 media captures over 90% of airborne particles between 1-10 microns and 50-70% of particles between 0.3-1 microns, including dust, pollen, pet dander, mold spores, smoke, bacteria, and viruses
• Activated carbon layer reduces household odors from cooking, pets, and smoke
• Custom-cut to exact dimensions of 16.5 x 21 x 0.75 inches to fit non-standard filter openings
• Reinforced 2-part filter frame provides added structural durability while supporting consistent airflow
• Maintains low airflow resistance to help the HVAC system run efficiently and extend filter service life
• Made in the USA

Compatibility

Designed as a custom OEM-style replacement for residential and light-commercial forced-air furnace and AC systems with a non-standard filter opening that accepts a nominal 16-1/2 x 21 x 1 inch filter. Verify the actual opening dimensions before ordering, as this item is made to the exact size specified and is not eligible for return.

Installation Notes

This filter is installed by HVAC technicians or qualified DIYers. Power down or set the thermostat to the off position before removing the existing filter to prevent unfiltered air from circulating through the air handler. Confirm airflow direction is correct by aligning the arrow printed on the filter frame with the direction of airflow toward the blower. Replace 1-inch filters every 30-90 days depending on household conditions such as pets, dust levels, and occupancy.
