The air filters of your commercial HVAC unit are your building’s first line of defense against contaminated air. They trap particles such as dust, pollen, fibers, and other potentially harmful pollutants. They also ensure that your HVAC unit isn’t being bogged down by dirt and grime.
Your air filters will need to be changed once a month to prevent trapped dirt from restricting airflow to the unit. However, some commercial businesses, such as chemical plants or manufacturing companies, produce more air pollutants than others. For these businesses, it may be necessary to check and change your air filters weekly.
