As the world continues to grapple with the novel coronavirus, many people are looking for ways to protect themselves and their families from the virus that causes COVID-19. While no portable air filtration system has been proven to filter COVID-19, research supports an air purifier's ability to filter common airborne viruses, provided that the system captures infected air. One of the ways many people are trying to protect themselves from COVID-19 is by upgrading their HVAC filters and purchasing air filtration systems. The Centers for Disease Control and Prevention (CDC) recommends using ventilation filters that are as efficient as possible, without having a detrimental effect on the overall performance of the HVAC system. Portable air filters and HVAC filters can reduce indoor air pollutants, including viruses, found in the air.
However, on their own, these filters aren't enough to protect people from the virus that causes COVID-19. Prior to a filtration upgrade, the specific filters in question should be investigated to determine their pressure drop rates at intended use flow rates and the potential impacts of that pressure drop assessed based on the capabilities of the existing HVAC system. One of the ways you can improve the air quality in your home is to improve the filter in your HVAC unit. Consider running the system fan longer, or continuously, since HVAC systems filter air only when the fan is running. When used in conjunction with other practices recommended by the CDC, an improved HVAC filter can be part of a plan to protect you and your family.
Use protection when changing the filter, as particles inside the filter may contain live viruses. According to the CDC, an improved HVAC filter can improve the air quality in your home. While no portable air filtration system has been proven to filter COVID-19, research supports an air purifier's ability to filter common airborne viruses, provided that the system captures infected air.
