Nordic Pure 18x28x1ExactCustomM14+C-6 Merv 14 Carbon Filter

Product Description

The NORDIC PURE 18x28x1ExactCustomM14+C-6 is a custom-cut, pleated air filter with activated carbon media, rated MERV 14 Plus Carbon for high-efficiency particulate and odor control. Sized at an actual 18 x 28 x 0.75 inches, this filter is hand-made to exact dimensions and ships in a 6-pack. It is designed for installation in residential and light-commercial HVAC systems where standard nominal sizes do not fit. MERV 14 filtration captures over 90 percent of airborne particles between 1 and 10 microns and 75 to 95 percent of particles between 0.3 and 1 microns. Licensed HVAC technicians and qualified service professionals are the primary installers of this filter type.

This filter is suited for forced-air furnace and central air conditioning systems that require a non-standard filter footprint. The custom construction uses cut-down or combined filter frames, which may include tape reinforcement depending on final dimensions. The reinforced 2-part frame supports balanced airflow and consistent filtration performance over the filter life cycle. Recommended change interval for 1-inch filters is every 30 to 90 days depending on environmental conditions such as pet dander load, dust levels, and local air quality. This listing covers a 6-pack of filters at the exact nominal size of 18x28x1.

Compatibility

Designed as a custom-size OEM-style replacement filter for residential and light-commercial forced-air furnace and central air conditioning systems requiring an actual filter dimension of 18 x 28 x 0.75 inches. Measure the existing filter before ordering - custom sizes are not eligible for returns.

Installation Notes

Filter installation should be performed by a licensed HVAC technician or qualified service professional. Always shut down the air handler or furnace at the disconnect or thermostat before removing the old filter and inserting the new one. Confirm airflow direction arrows on the filter frame align with system airflow before securing the filter housing. Because this is a custom-made product, verify the actual opening dimensions with a tape measure prior to ordering - the actual size should match within 1/8 inch of the opening.
