Nordic Pure 18x18x1M7-3 Pleated Air Filter Merv 7 3 Pack

Product Description

The NORDIC PURE 18x18x1M7-3 is a MERV 7 pleated air filter sold in a 3-pack, designed for residential and light commercial HVAC systems including central air conditioners and gas or electric furnaces. Each filter measures 17.75 x 17.75 x 0.75 inches actual size with a nominal size of 18x18x1. The electrostatically charged, hypoallergenic filter media captures large airborne particles such as household dust, pollen, mold spores, and pet dander on every pass. The moisture-resistant beverage board frame holds its shape under normal HVAC airflow conditions. This MERV 7 rating is equivalent to MPR 600 on manufacturer-specific rating scales.

This filter is suited for residential homes and light commercial spaces using standard 1-inch filter slots in forced-air HVAC equipment. It performs well in environments with pets, moderate dust, or occupants sensitive to airborne allergens. ASHRAE established the MERV standard to provide a consistent efficiency measure across all filter brands, making cross-brand comparisons straightforward. Filters should be replaced every 1 to 3 months depending on indoor conditions. Homes with pets, high dust activity, or ongoing construction should replace filters more frequently to maintain airflow efficiency and indoor air quality. Made in the USA.

Compatibility

Always verify the actual opening dimensions before installation, as nominal and actual filter sizes differ across equipment manufacturers.

Installation Notes

Licensed HVAC technicians and qualified service personnel should power down the furnace or air handler at the disconnect or thermostat before servicing the filter compartment. Confirm airflow direction arrows on the filter frame align with the direction of air movement toward the blower. Nominal size is a label only - measure the actual filter slot to confirm the 17.75 x 17.75 x 0.75 inch actual size fits before installation. Dispose of used filters per local waste guidelines.
