What type of filters are commonly used to enhance indoor air quality in HVAC systems?

HEPA filters, which stands for High Efficiency Particulate Air filters, are specifically designed to capture a wide range of airborne particles, including dust, pollen, pet dander, and even some bacteria and viruses. This makes them highly effective at improving indoor air quality, especially in environments where clean air is essential, such as homes with allergy sufferers or in healthcare facilities.

HEPA filters can trap particles as small as 0.3 microns with an efficiency of 99.97%, enabling them to significantly reduce allergens and contaminants in the air. This high level of filtration contrasts with other types of filters, which might not provide the same level of effectiveness in removing small particles or specific pollutants.

In contrast, charcoal filters primarily focus on adsorbing odors and some volatile organic compounds (VOCs), but they do not filter out particulate matter as effectively as HEPA filters. Electrostatic filters use static electricity to attract particles, and while they can be efficient, they may not reach the same level of particulate capture as HEPA filters. Oil filters are entirely unrelated to air filtration in HVAC systems, as they are designed for filtering substances like oil in mechanical systems. Thus, HEPA filters are the preferred choice for enhancing indoor air quality in HVAC
