What is the primary function of HEPA filters in air filtration devices?

The primary function of HEPA (High-Efficiency Particulate Air) filters is to capture debris and particulate matter, which significantly improves air quality and contributes to healthier indoor environments. These filters are designed to trap a wide range of particles, including dust, pollen, pet dander, and mold spores, which are common allergens and contaminants that can compromise air quality.

By effectively removing these particles from the air, HEPA filters help reduce the risk of respiratory issues and allergies, making living and working spaces safer and more comfortable. Their efficiency in trapping particles as small as 0.3 microns is a key reason they are widely recommended for use in homes, hospitals, and various environments requiring clean air.

The other options do not relate to the core function of HEPA filters. Increasing humidity levels and regulating temperature pertain to different devices or systems, such as humidifiers and HVAC systems. Enhancing odors typically involves air fresheners or other scent-producing products, not HEPA filters, which are solely focused on filtration and not on modifying scent or humidity.
