Can Air Purifiers Prevent the Spread of COVID-19? | DuctWorks Heating & Air Conditioning
COVID and Filters
Air purifiers are appliances designed to cleanse the indoor air. They work by circulating the air in your home and filtering out any pollutants. COVID-19 is a disease that spreads when saliva droplets or mucus from an infected person come into contact with an uninfected person's respiratory organs. Air purifiers are designed to play a significant role in curbing the spread of COVID-19. Installing these appliances on the floor area and at high levels in the house is advised because it ensures that droplets follow the airflow to the purifier. Overall, air cleaning substantially helps in managing the spread of the virus from an infected person in the following ways:

Mitigation of pathogens in the air

In an environment with sick people, pathogens are a common occurrence. An air purifier can filter out air pollutants, including dust, smoke, and disease-causing microorganisms found in the air. When an infected person coughs or sneezes without fully covering their mouths, they emit infected droplets into their environment. With an air purifier, these droplets will be absorbed into the appliance leaving the air clear and safe for other people.

Blowing air through the filter

Air purifiers work by blowing air through a filter to remove any droplets present in your surrounding air. If the droplets are virus-filled, the screen will strain out the droplets. However, it is worth mentioning that the filtration process takes some time to go through all the air around your room. As this cycle occurs, some viruses may land on flat surfaces, which will need proper cleaning to prevent the spread of the disease.

Capturing the Coronavirus

Air purifiers have filters that capture both large and small particles. When you cough, breathe, or talk, the particles move through the air and maneuver their way through the filter fibers. Some air purifiers are very effective at capturing coronavirus particles that they travel through the air. Capturing the virus particles can be more effective if the air purifier cycles air through the filter faster. Ideally, a faster operation ensures all infected droplets are arrested before they drop to flat surfaces. The clean air delivery rate number attached to the purifier can readily tell you the degree of efficiency of the appliance. If you have a COVID-19 patient in the house or hospital, running an air purifier throughout days and nights in their isolation room helps protect the caregiver and loved ones from the virus.
