DuPont Air Filters
DuPont Air Filters furnace filters come in many standard sizes, and are interchangeable with other brands that are the same size. While we may not carry the DuPont Air Filters brand specifically, we do have size-matched replacements for the filter you need.
For most sizes you will have several options to choose from so you can get a higher quality filter or save a little money with a cost efficient model. Using the drop-down boxes to the left, enter the dimensions from your existing filter.
DuPont replacement filters are a perfect choice for residential dwellings and commercial furnace applications. These filters are comparable to the original replacement filters but at a fraction of the price.
Discount replacement filters for DuPont furnace filters are offered in a number of sizes and varieties. Original Equipment Manufacturer, or OEM, replacement filters will meet specifications set forth by the manufacturer and so will the non-OEM products that we offer. The non-OEM filters have a Minimum Efficiency Reporting Value (MERV) rating from 4 to 13, which means the higher rated filters are capable of removing 95% of particulates in the air. MERV 13 rated filters are capable of removing airborne allergens smaller than 1 micron.
These discount replacement filters are made with a fully synthetic media that is chemical free. The media is electrostatically charged, which attracts the pollutants and helps then adhere to the filter, thereby reducing fine particulates in the air. The frame is made of 30 gauge galvanized metal and it is wrapped with a beverage board frame that resists moisture, mold and mildew.
These pleated discount replacement filters have a low pressure drop that inhibits microbial growth and allows the ventilation system to operate at a higher efficiency. The filters should be replaced every three months. You should regularly inspect the filter between scheduled replacements in order to keep your HVAC system operating at its highest potential. These filters drastically improve the quality of the air in every room and, at times, can require more frequent replacement. This is especially true during the allergy seasons.
There is no minimum order size on this website. Shipping is free and there aren't any hidden fees. If a return is needed, the filters need to be in the same condition as when they were shipped and in the original packaging. Returns must be made within a year.
