Other brands of air filters claim to not promote the growth of bacteria and mold on their filters. Can this be 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. 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.
