There has been much written about the benefit of air filters and air purifiers and consumers are constantly being reminded to clean and replace air filters to keep their air purifiers working. But do these products really clean the air? While clean air filters can be somewhat effective, experts caution that many indoor pollutants are immune to these filters and can easily escape into the air inside your home.

Most experts agree that air purifiers which are considered “passive electrostatic” are not effective – even with a clean filter. “Many common allergens do not float in the air because they are too heavy. These allergens and germs remain on the ground or other surfaces and rarely if ever reach the electrostatic plates of air purifiers,” according to, “…the passive electrostatic air purifiers may offer some piece of mind, but very little actual health benefit.”

Dust, pollen and smoke are not the only pollutants. The Environmental Protection Agency (EPA) reports indoor particles can contain dangerous gaseous pollutants which “…come from combustion processes. Sources include gas cooking stoves, vehicle exhaust, and tobacco smoke.” These also include building materials, furnishings, and the use of products such as paints, and varnishes, cleaning products, and pesticides.

According to the EPA, gas-phase air filters can help to remove gases and odors with a material called sorbent. However, while these filters are intended to remove gaseous pollutants, these gas-phase filters are “…specific to one or a limited number of gaseous pollutants,” reports to the EPA. “… (and) none are expected to remove all of the gaseous pollutants present in the air of a typical home.” The EPA points to carbon monoxide as an example – as that is a “…dangerous gaseous pollutant that is produced whenever any fuel such as oil, kerosene, wood, or charcoal is burned, and it is not readily captured using currently available residential gas-phase filtration products.”
