Nordic Pure 18x20x1M16-4 Pleated Air Filter Merv 16

Product Description

The NORDIC PURE 18x20x1M16-4 is a MERV 16 pleated air filter designed for residential and commercial HVAC systems where high-efficiency particulate capture is required. It ships as a 4-pack with a nominal size of 18x20x1 and an actual size of 17.75 x 19.75 x 0.75 inches. The advanced pleated media increases filtration surface area, capturing ultrafine particles including smoke, bacteria, mold spores, pet allergens, and fine dust while maintaining low airflow resistance. A reinforced 2-part frame resists bending and bowing during the full service cycle. HVAC technicians and facilities maintenance professionals typically specify this filter in applications where indoor air quality must meet stricter standards.

This filter is suited for residential forced-air furnaces, central air conditioning systems, and light commercial air handlers where a nominal 18x20x1 filter slot is used. The MERV 16 rating makes it appropriate for environments with elevated air quality concerns such as homes with allergy sufferers, pet dander, or smoke exposure, as well as commercial settings requiring higher filtration efficiency. Nordic Pure recommends replacing 1-inch filters every 30 to 90 days depending on environment and air quality conditions.

Installation Notes

Installation should be performed by a qualified HVAC technician or knowledgeable service professional. Power down the air handler or furnace at the disconnect before removing or installing any filter. Confirm airflow direction arrow on the filter frame is oriented toward the blower, not the return duct. Inspect the filter slot and frame rails for gaps or bypass leakage before completing reassembly.
