Indoor air quality (IAQ) refers to the air quality within building structures, especially as it relates to the health and safety of building occupants. Proper IAQ is a growing concern of homeowners across the country as they look to reduce the risk of indoor health concerns. Appropriate ventilation and strong indoor air quality not only reduce the risk of indoor pollution, but they also play a big role in virus prevention within the home.

COVID-19 and Other Viruses

The rapid spread of several COVID-19 variants, as well as common cold and flu viruses have left people with the question of what they can do to help stop the spread. In order to stop the spread of COVID and other viruses it is best to maintain social distancing, wash your hands frequently, and sanitize common areas. As businesses and schools have made the decision to bring individuals back into group settings, it is important to understand the role that proper indoor ventilation can play in keeping everyone safe.

Ventilation Rate & Air Change Rate: Why They Are Important for Virus Prevention

As individuals consider going back to group settings, understanding air quality terminology can help you ask the right questions.

  • Ventilation rate is the volume of outside air provided per unit of time
  • Air change rate is the ventilation of a space divided by the volume of that space.

Essentially, both rates inform you on how fast the room can be cleared of any airborne contaminants. With all airborne viruses, especially COVID, the faster you can clear out contaminants the lower the risk of virus transmission. Clean IAQ and increased ventilation has been proven to reduce transmission of airborne viruses and diseases by lowering the concentration of infectious particles in the air.

Prevention is always going to be the best method of combating these unseen threats. One of the best ways to prevent the spread of these viruses throughout your home is to utilize indoor air quality solutions such as the Aerus Air Scubber and iWave Air Purifier.
