Activated carbon filters, on the other hand, absorb VOCs due to their large surface area and porous structure. UV-C light filters can kill bacteria and viruses but do not specifically target VOCs. -
Mechanisms of action:
Absorption occurs when VOCs adhere to the surface of the activated carbon, thus removing them from the air. Chemical reactions can also neutralize certain VOCs. Particle filtration physically traps airborne solids but is less effective against gaseous pollutants. -
Perspectives on effectiveness:
Supporters claim that air purifiers significantly improve indoor air quality and reduce health risks associated with VOC exposure. Skeptics argue that not all air purifiers are equally effective, and some may only provide a false sense of safety. Furthermore, opinions vary on whether air purifiers are necessary or if adequate ventilation can achieve similar results for VOC reduction. Evidence points to varying degrees of effectiveness depending on the type of VOC and the capacity of the air purifier, as noted by a study conducted by the EPA in 2018.
