Air Quality & COVID-19

COVID-19 is a highly infectious disease compared to its 2003 counterpart, SARS. Its health effects vary among people from having no symptoms at all to having severe respiratory distress. According to CDC reports, people with serious underlying medical conditions are “at higher risk for severe illness from COVID-19.”

Scientists also found that air pollution contributes to the severity of the disease. A nationwide study, conducted by Harvard University, showed that counties in the USA with high levels of air pollution before the COVID-19 crisis have higher death rates (defined as COVID-19 deaths per total population).


Levels of the uHoo Virus Index

These levels are determined based on scientific analysis of five air quality factors which include Temperature, Relative Humidity, PM2.5, Carbon Dioxide, and Nitrogen Dioxide.

  • Good: COVID-19 survival is low and airborne transmission is unlikely.
  • Mild: COVID-19 survival is moderate and airborne transmission is possible but air quality poses little to almost no direct health risk for people not sensitive to air pollution.
  • Bad: COVID-19 survival is prolonged and airborne transmission is likely.
  • Severe: COVID-19 survival is high and airborne transmission is likely.



Know What You Are Breathing

We can't fight air pollution unless we understand the source.
Protect your loved ones by knowing what gases, allergens and toxins we are exposed to.
Work in peace and breathe with ease knowing the air around you is safe and healthy.

We take about 20,000 breaths each day and indoor air is two to five times worse than outdoors (Source: US EPA).
CSIRO estimates the cost of poor indoor air quality in Australia may be as high as 12 billion per year (Brown,1998).
Unless we have a problem, we don’t think about what we’re breathing and how that air is affecting us.
