The NORDIC PURE 13x18x1ExactCustomM13-6 is a custom-made, pleated AC furnace air filter rated MERV 13, sized at an exact actual dimension of 13 x 18 x 0.75 inches. Sold in a 6-pack, these filters are hand-cut to the specified exact dimensions and are designed for residential and commercial HVAC systems. The electrostatically charged pleated media captures a wide range of airborne contaminants, delivering high-efficiency filtration while maintaining low airflow resistance. Licensed HVAC technicians and experienced homeowners install these filters as part of routine system maintenance to protect indoor air quality and equipment performance.
These MERV 13 filters are suited for residential and light commercial applications where air quality is a priority, including homes with allergy sufferers or pets. MERV 13 efficiency is comparable to MPR 2200-2400 rated filters. Nordic Pure recommends replacing the filter every 1 to 3 months depending on environmental conditions. Households with pets or allergy concerns may require more frequent changes. The filters are custom-fabricated to the exact dimensions entered at time of order using one, two, or three filter frames, which may include tape reinforcement depending on size.
Designed as an exact custom-size replacement pleated furnace filter for residential and commercial HVAC systems requiring a 13 x 18 x 0.75 inch actual-dimension filter. Measure the existing filter carefully before ordering, as nominal size and actual size differ on nearly all AC furnace filters. Custom-made orders are not eligible for return.
Installation is performed by HVAC technicians or qualified homeowners as part of routine filter maintenance. Always power down the HVAC system at the thermostat or disconnect before removing the existing filter. Confirm airflow direction arrow on the filter frame aligns with the direction of airflow into the air handler or furnace. Because these filters are custom-fabricated to exact dimensions, verify measurements to the fraction of an inch before ordering.
