Frequently Asked Questions
DuPont™ Air Filters offer a wide variety of solutions to help make the air in your home cleaner & healthier. Here are answers to some of the most commonly asked questions about DuPont™ Air Filters.
Can DuPont™ Air Filters really improve my indoor air quality?
For every visible particle trapped in your furnace filter such as dust, dirt, and mold, there are as many as 100 more that you cannot see, including bacteria, fungi, and pollen. If not stopped, these micro particles can seep through your HVAC system and back into your air. So the answer is YES, the air in your home can be cleaner.
Why is Microban® product protection so important 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 microorganisms can multiply on unprotected surfaces, potentially resulting in odors and adversely affecting 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.
Other brands of air filters, without Microban®, claim to not promote the growth of bacteria and mold on their filters, is this true?
This is only partially true. Many high performance filters today are made from synthetic fibers. Filters that are made from synthetic fibers are generally made from materials that bacteria and other microorganisms cannot process as a food, so the bacteria and mold do not grow on the filter. However, filters with synthetic media can still have bacteria and other microbes growing on the media. That’s because any bacteria or microbes trapped on a filter will be able to feed off of other matter that is also trapped on the filter – things like pet dander, and pollen for example.
Do pleated filters actually provide better filtration than filters that are not pleated?
The filter media determines the level or quality of filtration that a filter provides. Pleated filters provide two advantages over un-pleated filters: (1) pleating provides more surface area to increase dirt holding capacity, and (2) pleating helps more evenly distribute the air flow over the surface of the filter.
Why are DuPont™ Air Filters more advanced compared to other air filters?
DuPont™ Air Filters include rigid frame construction with Microban® antimicrobial product protection and OGuardTM technology to provide you with an advanced air filter for your home’s heating and/or cooling system. DuPont™ Air Filters are engineered with the latest in filter media technology to trap even microscopic particles that may affect indoor air quality. It's the “science inside” that makes our filters so special. DuPont™ Air Filters provide you with many different options to meet almost any air filtration need in your home.
What do I do if I cannot find a DuPont™ filter in my size?
Not all stores carry all sizes of DuPont™ Air Filters. If a store does not carry your size air filter ask the store associate if they can special order the size for you. There are also several styles of cut-to-size filters available.
How do I decide which filter is best for my home?
DuPont™ Air Filters bring a whole new level of protection & performance to your indoor environment. Whether your main concern is pollen, pet dander, odor, smoke particles, dust, or all of the above, DuPont offers a filter to meet your family’s air filtration needs.
