What is the function of filtration in an air conditioning system?

Filtration in an air conditioning system primarily serves the crucial role of removing contaminants from the air. Air filters are designed to capture dust, pollen, pet dander, and other particulates, thereby improving indoor air quality. By trapping these particles, filtration helps to ensure that the air circulated throughout the space is cleaner and healthier for occupants. This process can prevent allergens and irritants from being redistributed in the environment, which is particularly beneficial for individuals with respiratory issues or allergies.

While heating, lowering humidity levels, and increasing oxygen supply may be functions associated with different components or systems in HVAC or environmental control, they do not specifically pertain to the primary purpose of filtration within an air conditioning system. The importance of a reliable filtration system cannot be overstated, as it directly impacts comfort and health in indoor environments.
