Nordic Pure 12x20x1M10MiniPleat-4 Merv 10 Air Filter 4 Pack

Product Description

The NORDIC PURE 12x20x1M10MiniPleat-4 is a MERV 10 rated mini-pleat air filter designed for residential and light commercial HVAC systems. It ships in a box of 4 filters with a nominal size of 12x20x1 and an actual size of 11.5 x 19.5 x 0.75 inches. The polyester filter media is self-supporting and engineered with 2.5 times more pleats than standard filters, increasing surface area for improved particle capture. A heavy-duty, two-part moisture-resistant beverage board frame holds the media in place and resists warping. Licensed HVAC technicians and experienced DIYers install this filter in forced-air furnace and air handler applications.

This filter is suited for residential homes and commercial buildings using standard 1-inch filter slots. The higher pleat density captures lint, dust, pollen, pet dander, dust mites, and mold spores while maintaining adequate airflow through the system. A replacement interval of every 2 to 3 months is typical, though environments with pets, renovation activity, or elevated dust levels may require more frequent changes. The actual size of 11.5 x 19.5 x 0.75 inches fits filter slots commonly labeled as 12x20x1 nominal.

Key Features

• MERV 10 filtration rating, equivalent to MPR 800-1000, captures common airborne particles including pollen, dust mites, and mold spores
• 2.5 times more pleats than standard filters increases surface area and particle capture without significantly restricting airflow
• Self-supporting polyester media resists mold growth and maintains shape throughout the filter life
• Heavy-duty two-part moisture-resistant beverage board frame reduces warping and frame failure
• Actual size of 11.5 x 19.5 x 0.75 inches ensures a proper fit in slots with a 12x20x1 nominal label
• Manufactured in the USA

Compatibility

Designed as an OEM-style replacement for residential and light commercial HVAC systems using a 12x20x1 nominal filter slot. Always verify the actual filter opening dimensions against the actual size of 11.5 x 19.5 x 0.75 inches before installation, as nominal and actual sizes differ across equipment manufacturers.

Installation Notes

A licensed HVAC technician or qualified service professional should confirm airflow direction before inserting the filter, as arrows on the frame must align with system airflow toward the blower. Power down the air handler or furnace at the disconnect or thermostat before removing the old filter and installing the new one. Verify the actual slot dimensions match the actual filter size to avoid bypass gaps around the filter frame. Filters in high-load environments should be inspected at 30-day intervals regardless of the standard replacement schedule.
