Nordic Pure 18x30x1M14-4 Pleated Air Filter Merv 14

Product Description

The NORDIC PURE 18x30x1M14-4 is a MERV 14 pleated air filter sold in a 4-pack, designed for forced-air HVAC systems in residential and commercial applications. Each filter measures 17.75 x 29.75 x 0.75 inches actual size with a nominal size of 18x30x1 inches. The electrostatically charged, hypoallergenic filter media captures airborne dust, pollen, mold spores, pet dander, smoke particles, bacteria, and virus carriers on each air pass. A moisture-resistant beverage board frame holds its shape under continuous airflow. MERV 14 efficiency is comparable to MPR 2800 on proprietary rating scales. Licensed HVAC technicians and knowledgeable end users install these filters in systems rated to handle MERV 14 or higher static pressure loads.

These filters are suited for residential and light commercial forced-air systems where occupants have allergy or respiratory concerns, or where indoor air quality standards require high-efficiency particulate control. MERV 14 filtration is also appropriate for commercial environments that mandate elevated filtration performance. Because of the higher airflow restriction associated with MERV 14-rated media, the HVAC system must be rated to support filters at this efficiency level or above. Newer high-efficiency systems designed for HEPA-adjacent filtration are well matched to this filter. Replacement every one to three months is typical, with shorter intervals recommended in pet-occupied spaces or high-dust environments.

Key Features

• MERV 14 rated media captures dust, pollen, mold spores, pet dander, smoke, smog, bacteria, and virus carriers
• Electrostatically charged, hypoallergenic, and antimicrobial filter media resists bacterial and mold growth on the filter surface
• Moisture-resistant beverage board frame maintains structural integrity in humid operating conditions
• Actual size 17.75 x 29.75 x 0.75 inches fits nominal 18x30x1 filter slots
• MERV 14 efficiency is equivalent to MPR 2800 rating
• Made in the USA

Compatibility

Designed as an OEM-style replacement for residential and commercial forced-air furnace and air conditioning systems with filter slots rated to accept MERV 14 filtration or higher and sized for a nominal 18x30x1 inch filter.

Installation Notes

HVAC technicians and qualified service personnel should power down the air handler or furnace at the disconnect before servicing the filter compartment. Confirm the system is rated for MERV 14 or higher before installation, as high-efficiency media increases static pressure and can reduce airflow in undersized systems. Verify the actual slot dimensions against the filter actual size of 17.75 x 29.75 x 0.75 inches before insertion. Install with the airflow arrow on the frame pointing toward the blower.
