Nordic Pure Plus Carbon air filters are made of electrostatically charged synthetic materials with an added carbon layer. For MERV ratings of 13 and 14 the carbon layer is a flat panel of activated charcoal. For MERV ratings of 8, 10 and 12 it is a dual material where the MERV rated media has been fused together with carbon and pleated together. The MERV rated material captures most airborne particulates and the carbon will help eliminate unwanted odors for a fresh, clean home or business. Odorous gases and vapors (VOC) are attracted to and held by the activated carbon material while maintaining excellent air flow properties. With each pass through the carbon pleated furnace air filter, the air in your living environment improves.
The effective life of your carbon AC air filter depends on both the inside and outside conditions in which you live. It is important to regularly change your furnace air conditioner filters especially during any home improvements for fresh, clean air in your home or office. We recommend that you change your 1" and 2" air filters every 30-90 days to maintain maximum efficiency and economy. Our 4, 5, and 6-inch air filter could last up to 6 months, depending on your home or office environment.
CONSTRUCTION: Custom carbon air filters are made by cutting down or combining 1, 2 or 3 A/C air filter frames. Depending on the size we may use tape to make your custom size air filters. So, they might not be pretty, but they WILL be strong.
RETURNS: Custom carbon AC furnace air filters are not returnable since we hand make them per your exact dimensions when you enter your air filter size above. Since you can NOT return custom sized air filters, please make sure you order the EXACT size you need to the fraction of an inch.
Important Note: Almost ALL furnace filters have a different "actual size" than the nominal size printed on the air conditioner filter. It's best if you measure your air filter for the EXACT size and compare it to our "Actual Size" - and then you can be sure your A/C air filter fits!
