Nordic Pure 18x24x1M16-4 Merv 16 Air Filter 4-pack

Product Description

The NORDIC PURE 18x24x1M16-4 is a MERV 16 pleated air filter designed for residential and commercial HVAC systems where high-efficiency particulate capture is required. Sold in a 4-pack, each filter measures an actual 17.5 x 23.5 x 0.75 inches, fitting nominal 18x24x1 filter slots. The MERV 16 rating places this filter at the top of residential-grade filtration, capturing smoke, bacteria, mold spores, pet allergens, and ultrafine pollutants. A reinforced 2-part frame resists bending and bowing during operation, and the pleated media design increases surface area to support low airflow resistance while maintaining filtration efficiency.

This filter is suited for residential homes, light commercial buildings, and environments where occupants require superior indoor air quality - including spaces with allergy or asthma concerns, pet dander, or elevated particulate loads. HVAC technicians and facilities maintenance professionals typically specify MERV 16 filters in systems designed to handle the associated static pressure increase. Nordic Pure recommends replacing 1-inch filters every 30 to 90 days depending on environmental conditions and air quality demands.

Key Features

• Pleated media design increases filtration surface area while maintaining low airflow resistance
• Heavy-duty 2-part reinforced frame resists bending, bowing, and wear over the filter life
• Pack of 4 filters supports consistent replacement scheduling
• Manufactured in the USA

Compatibility

Designed as a direct-fit replacement for nominal 18x24x1 filter slots in residential and light commercial forced-air heating and cooling systems that accept 1-inch pleated filters.

Installation Notes

Installation should be performed by a qualified HVAC technician or experienced facilities maintenance personnel. Always power down the air handler or furnace at the disconnect or breaker before servicing the filter. Confirm airflow direction marked on the filter frame matches the direction of airflow in the system before insertion. At MERV 16, static pressure demand is elevated - verify the air handler is rated to operate within acceptable external static pressure limits before upgrading from a lower-MERV filter.
