Science Inside

DuPont™ Air Filters are scientifically formulated to improve your indoor air quality at an affordable price.

Built-in Technology Makes Better Filters

DuPont™ Air Filters are engineered with the latest in filter media technology to trap even microscopic particles that may affect indoor air quality. In addition, DuPont™ Air Filters are able to do a better job of filtering the air in your home because the filters themselves are protected from the very airborne contaminants you want the filter to trap. Through a proprietary process, Microban® and OGuard™ are built-in to provide your filter with an added level of protection against contaminants that may adversely affect filter performance.
OGuard™ Technology Effective Against Household Odors
In controlled laboratory tests the OGuard™ active ingredient has been proven to be effective against a broad range of household odors, even tough fish odors. In fact, in a recent test against fish odors, OGuard™ technology was even more effective than baking soda.
Microban® Protection Fights Growth of Microbes on Air Filters
Today's high performance filters are capable of trapping micro particles, including some as small as bacteria and fungi, and are designed to last up to 90 days. Unlike some inert particles which may be trapped in your furnace/air conditioner filter, bacteria and fungi are living organisms. Under certain conditions these micro organisms can multiply on unprotected surfaces, potentially resulting in odors and adversely affecting the performance of the filter media. The presence of Microban® product protection in the filter materials is not intended to affect airborne micro organisms, but can help reduce the uncontrolled growth of odor causing microbes on the surface of the filter material itself, where you need it the most.
*Test performed under controlled laboratory conditions according to AATCC 100 protocol using untreated filter media and media with Microban® antimicrobial protection. Bacterial population on the untreated media increased significantly, while bacterial population on the media with Microban® protection was reduced significantly. This testing was performed to substantiate the media’s antimicrobial activity against non-public health organisms. Microban® protection inhibits the growth of microbes that can cause odors and adversely affect the filtration media. Test results on file
