The definition of HVAC filtration is the process of removing particles, contaminants, and other impurities from the air. This is done through the use of filters, which are designed to capture and trap these particles before they can enter the air. HVAC filtration is important for both indoor air quality and the efficiency of the HVAC system. By removing these particles, the air is kept clean and the system is able to run more efficiently. The type of filter used will depend on the type of particles that need to be removed. For example, some filters are designed to capture dust, pollen, and other airborne particles, while others are designed to capture smoke, fumes, and other gaseous contaminants. The size of the particles also needs to be taken into consideration when selecting the right filter. It is important to ensure that the filter is capable of trapping the particles that need to be removed. HVAC filtration is an important part of maintaining a healthy and comfortable indoor environment. By removing contaminants from the air, the air is kept clean and the system is able to run more efficiently.
