Question: 1 / 400

What is the purpose of air filtration in HVAC systems?

The removal of odors from indoor environments

The process of removing airborne particles and contaminants to improve indoor air quality

The primary purpose of air filtration in HVAC systems is to remove airborne particles and contaminants, thereby improving indoor air quality. This process involves using filters that can trap dust, pollen, pet dander, mold spores, and other pollutants that may be present in the air. By capturing these particles, air filtration systems contribute to creating a healthier environment for occupants, reducing allergy symptoms and respiratory problems.

Good indoor air quality is essential for comfort and health, and effective air filtration is a critical component of HVAC systems designed to achieve this goal. While addressing odors, temperature regulation, and moisture control are important aspects of HVAC operation, they are not directly related to the primary function of air filtration, which focuses specifically on the removal of particulates and contaminants from the air.
