Nordic Pure Merv 13 Plus Carbon Furnace Filter 6 Pack

Product Description

The NORDIC PURE 20x22_1/4x1ExactCustomM13+C-6 is a custom-cut, pleated MERV 13 plus carbon air filter sized to exact dimensions of 20 x 22.25 x 0.75 inches. It is designed for residential and light commercial HVAC systems where a non-standard filter size is required. 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. The activated carbon layer addresses odors and gaseous contaminants. Licensed HVAC technicians and experienced DIYers install this filter in forced-air furnace and air conditioning systems. The pack includes 6 filters.

This filter is suited for residential forced-air systems with non-standard filter openings that cannot accommodate a stock size. It targets environments with elevated concerns about allergens, pet dander, smoke, mold spores, bacteria, viruses, and household odors. Because it is built to exact listed dimensions, it is appropriate only for equipment where the measured actual filter slot matches 20 x 22.25 x 0.75 inches. The reinforced two-part frame supports consistent airflow and balanced filtration across the full service life of the filter. Recommended replacement interval for 1-inch filters is every 30 to 90 days depending on environmental conditions.

Key Features

• MERV 13 filtration captures over 90% of particles between 1 and 10 microns and 50% to 70% of particles between 0.3 and 1 micron
• Activated carbon layer reduces odors from smoke, pets, and household sources
• Custom-cut to exact dimensions of 20 x 22.25 x 0.75 inches - not a nominal or oversized fit
• Reinforced two-part frame provides added structural durability and supports efficient airflow
• Pleated media design maintains low airflow resistance to reduce strain on the blower motor
• Made in the USA

Compatibility

Designed for forced-air furnace and air conditioning systems requiring a custom actual-size filter of 20 x 22.25 x 0.75 inches. Measure the existing filter slot carefully before ordering, as this is a non-returnable custom-made item. Verify that no standard nominal size fits the application before selecting a custom size.

Installation Notes

Installation is typically performed by a licensed HVAC technician or a knowledgeable DIYer familiar with forced-air system maintenance. Before replacing the filter, set the thermostat to off and, where applicable, shut down the air handler at the unit disconnect. Confirm airflow direction arrow on the filter frame aligns with the direction of air movement toward the blower. Because this is a 0.75-inch-thick filter, replacement every 30 to 90 days is recommended in most residential environments.
