Nordic Pure 13x21.5x1CM8-3 Merv 8 Air Filter 3 Pack

Product Description

The NORDIC PURE 13x21.5x1CM8-3 is a MERV 8 pleated air filter sold in a 3-pack, sized at a nominal 13x21.5x1 inches with an actual size of 13 x 21.5 x 0.75 inches. Designed for use in residential and light commercial HVAC systems, this filter captures lint, dust, pollen, bacteria, pet dander, dust mites, and mold spores on every pass. The electrostatically charged filter media improves particle attraction without restricting airflow. Licensed HVAC technicians and knowledgeable service pros install these as routine maintenance items in forced-air furnace and air conditioning systems. The MERV 8 rating aligns with the ASHRAE standard and is comparable to an MPR 800-rated filter.

This filter is suited for residential forced-air furnaces and split-system air conditioners as well as light commercial applications requiring MERV 8 filtration. It is a direct replacement for Carrier OEM-sized filters with a nominal dimension of 13x21.5x1. The filter media is antimicrobial and will not promote bacterial or mold growth on the media surface. Replacement is recommended every one to three months under normal conditions. Homes with pets or allergy sufferers may require more frequent changes. Regular replacement supports system efficiency and maintains indoor air quality.

Installation Notes

Filter replacement is a standard HVAC maintenance task performed by licensed HVAC technicians or qualified service personnel. Before replacing the filter, set the thermostat to off and confirm the air handler or furnace blower has stopped. Note the airflow direction arrow on the filter frame and orient the replacement filter to match. Follow local mechanical codes and the equipment manufacturer's maintenance schedule for replacement intervals.
