Half Inch AC Furnace Air Filters consist of an internal frame bonded between flat layers of two different types of electrostatically charged filter media. The first layer is a polyester filter media which acts as a pre-filter. The second layer is a MERV rated smooth poly-blend filter material. It is our opinion this double media half inch air filter is more effective than the half inch pleated air filter. It is more efficient therefore you are getting 2 for 1 air filters. The electrostatic charge of the air filters works as a magnet to draw airborne particles. In combination, the half inch (1/2") Double Media Air Filters provide exceptional air filter capacity and remarkable air filter efficiency. We offer almost any size half inch AC furnace air filter you are looking for.

Nordic Pure is very proud of this exciting product that we offer in most all sizes! The Half Inch AC Furnace Air Filter gives our customers the best of both worlds. The first layer has a high capacity, which means it will capture and hold large air particles. This feature prolongs the life of the air filter and enables the second, more efficient, layer to capture the smaller air particles. Half Inch AC Furnace Air Filters are especially great for apartments, campers, boats, buses, RVs, AC and heater window units, and any air system that requires half inch (1/2") air filters.

IMPORTANT Note: Air filters have an actual size that is a fraction of an inch smaller than the standard size (also known as "nominal size"). The size printed on your current air filter may NOT be the actual size. Please measure your current air filter to make sure you order the correct size. Some half inch air filters are custom sized.

Nordic Pure, manufacturer direct since 1960. We manufacture high efficiency air conditioner, furnace, and ring panel filters for commercial and residential use in a range of MERV ratings. They capture microscopic airborne dust, pollen, allergens, mold spores, pet dander, bacteria and particulates carrying bacteria and viruses in the air. The higher the MERV rating, the better the filtration. Our MERV 12 and MERV 13 air filters, which capture up to 98.9% of airborne particles, are best for people suffering with allergies and other breathing issues. We can make most all sized custom HVAC air filters for a low cost and Free Home Delivery. Our non-woven synthetic air filters media will not support the growth of mold or bacteria, keeping your home healthier. Our air filters use permanently electrostatically charged material that helps dust cling to the air filter. This helps protect your AC unit, home and family.

Generally you should change your air filter every 30, 60, or 90 days. Replacing your air filter is the first step in insuring your HVAC unit is running at its optimal level. Air filters are ranked in a minimum efficiency rating value (MERV) system. We currently offer MERV 7, MERV 8, MERV 10, MERV 11, MERV 12, MERV 13, MERV 14, and MERV 15 air filters. The higher the MERV rating, the better the efficiency. Nordic Pure is constantly trying to improve indoor air quality and the half inch AC furnace air filters are another product we proudly offer.
