The objective of an air conditioning unit designed for clean air is to enhance indoor air quality. This can involve filtering out various pollutants like dust, pollen, pet dander, mold spores, and volatile organic compounds (VOCs). For instance, a unit might employ a HEPA filter to trap microscopic particles or an activated carbon filter to adsorb gases and odors. Some advanced systems may even utilize ultraviolet (UV) light to neutralize bacteria and viruses.
Improved indoor air quality offers numerous advantages, including reduced allergy and asthma symptoms, better sleep, increased productivity, and an overall healthier living environment. Historically, indoor air quality was not a primary concern in AC design. However, with growing awareness of the impact of indoor pollutants on health and well-being, the focus has shifted towards incorporating air purification technologies into modern AC systems. This evolution reflects a broader societal trend toward prioritizing health and sustainability.
