Nordic Pure 17x21x1ExactCustomM12-12 Merv 12 Furnace Filter 12 Pack

Product Description

The NORDIC PURE 17x21x1ExactCustomM12-12 is a custom-made, MERV 12 rated pleated air filter designed for residential and light commercial HVAC systems, including forced-air furnaces and central air conditioners. Rated at MERV 12, this filter captures over 90% of airborne particles between 3 and 10 microns and 80% to 90% of particles between 1 and 3 microns. The electrostatically charged filter media attracts and holds contaminants including lint, dust, pollen, pet dander, mold spores, smoke particles, bacteria, and virus carriers. Each filter uses a heavy-duty, moisture-resistant beverage board frame and is manufactured to exact dimensions specified at time of order. This listing covers a 12-pack.

This filter is suited for residential homes and commercial spaces requiring mid-to-high efficiency particulate control without excessive static pressure drop. The MERV 12 rating is comparable to MPR 1500 to 1900 filters offered by other manufacturers. Custom sizing makes this filter appropriate for non-standard filter openings where off-the-shelf nominal sizes do not fit correctly. Licensed HVAC technicians and facilities maintenance personnel commonly install these filters during scheduled preventive maintenance cycles. Replacement is recommended every 1 to 3 months, with more frequent changes recommended in households with pets or occupants with allergies.

Compatibility

Designed as a custom exact-fit replacement filter for residential and commercial HVAC systems with a filter slot requiring a 17 x 21 x 0.75 inch actual-dimension filter. Verify the actual opening dimensions of your air handler or furnace filter rack before ordering, as this is a custom-made non-returnable item.

Installation Notes

Installation is performed by HVAC technicians or qualified maintenance personnel. Always shut down the HVAC system at the thermostat and disconnect power at the breaker before removing the existing filter. Confirm airflow direction marked on the filter frame matches the direction of airflow in the duct or air handler. Because this filter is custom-made to exact dimensions, measure the actual filter slot width, height, and depth with a tape measure before placing the order to ensure proper fit.
