How is Air Filtered in Commercial HVAC Systems?

There are a few different ways that air is filtered in commercial HVAC systems. The most common method is through the use of an air filter. Air filters are designed to remove airborne contaminants from the air that passes through them. They are typically made of paper or cloth and can be replaced when they become clogged with dirt and debris. There are also electronic air filters that use negative ions to trap dust and other particles, but these can be more expensive than traditional filtration systems.

UV Systems

Another common method of commercial HVAC system air filtration is through the use of UV lights. These are installed directly above cooling coils or heat exchangers, where mold and bacteria can grow. The UV light kills these contaminants, preventing them from being circulated back into the air.

HEPA Filters

HEPA filters are also sometimes used in commercial HVAC systems. HEPA stands for high efficiency particulate air and these filters are designed to remove 99.97% of all particles that are 0.3 microns or larger. These filters are used in applications where there is a high amount of dust or other pollutants in the air.

Custom Settings

In addition to these filtration methods, commercial HVAC systems can also be designed to improve ventilation and circulation within a building. This helps remove airborne contaminants from occupied spaces, particularly when large amounts of people gather in enclosed spaces. Proper ventilation and filtration can help ensure that air quality remains high in even the most common areas of commercial buildings.

As you can see, there are a variety of ways that air is filtered in commercial HVAC systems. Whether you are considering installing an HVAC system or have one already, it is important to understand how the air is being filtered so that you can get the most out of your system.
