- Carbon Dioxide (CO₂)
The measurement of the CO₂ (Carbon Dioxide) concentration provides a measure of what percentage of the air we inhale consists of air that has already been exhaled by other people, this is called the Rebreathed Fraction. An elevated rebreathed fraction equals a greater probability of the spread of infection.
- Particulate Matter (1 μm, 2.5 μm, 10 μm)
Covid-19 and other viruses can live in Particulates in the air and are the cause of Droplet and Airborne Transmission. When these particulates are inhaled they deposit into the respiratory system and deliver their virus payload.
- Humidity (RH)
Relative humidity plays an important role in the survival of virus’s in the air as well as how long they remain airborne.
- Volatile Organic Compounds (VOC)
Volatile Organic Compounds or VOCs, refer to organic chemical compounds that can adversely affect human health. They are emitted as vapors from certain solids or liquids and include a variety of chemicals. VOC is seen often in cleaning supplies, adhesives, paints, and air fresheners.
- Nitrogen Dioxide (NO₂)
The major sources of NO₂ are primarily emissions from vehicle exhaust gases, & domestic heating. Long-term exposure to NO₂ may cause a wide spectrum of severe health problems such as hypertension, diabetes, heart and cardiovascular diseases and even death.
