Nordic Pure 21_1/2x24x1ExactCustomM10-6 Merv 10 Filter 6pk

Product Description

The NORDIC PURE 21_1/2x24x1ExactCustomM10-6 is a custom-cut, MERV 10 rated pleated air filter designed for residential and light commercial HVAC systems, including central air conditioners and gas or electric furnaces. Rated at MERV 10, this filter captures over 85% of airborne particles in the 3-10 micron range, including lint, dust, pollen, pet dander, and mold spores. The electrostatically charged filter media attracts and holds contaminants without significantly restricting airflow. Each box contains 6 filters with an actual size of 21.5 x 24 x 0.75 inches, hand-cut to those exact dimensions.

This filter is suited for residential homes and commercial office environments where improved indoor air quality is a priority. It is particularly appropriate for households with pets or occupants who manage allergy or asthma symptoms. MERV 10 performance is comparable to filters rated MPR 900-1000 under other manufacturer rating scales. Nordic Pure recommends replacing this filter every 1-3 months depending on environmental conditions, with more frequent changes recommended in high-pet or high-dust settings. The custom sizing makes this filter appropriate for non-standard filter openings that standard nominal sizes cannot accommodate.

Compatibility

Designed as a custom exact-size replacement air filter for residential and light commercial HVAC systems with a filter opening requiring an actual size of 21.5 x 24 x 0.75 inches. Measure your existing filter opening before ordering, as this is a non-returnable custom-made product.

Installation Notes

Installation is performed by HVAC technicians or knowledgeable end users. Always power down the HVAC system at the thermostat and, where applicable, at the disconnect or breaker before removing or installing a filter. Confirm airflow direction arrows on the filter frame are oriented toward the blower, not toward the return duct. Because this is a custom-cut filter, verify the exact opening dimensions with a tape measure prior to ordering - custom sizes are non-returnable and cannot be exchanged.
