Virus Risk Indicator
Understand, monitor, and reduce airborne virus risk across your portfolio using real-time air quality data and insights.
How does airborne virus spread indoors?
Airborne viruses spread indoors through microscopic droplets that can linger in the air for hours and travel through a building's ventilation.
Three environmental conditions amplify or reduce that risk: humidity (which affects how long viruses survive in the air), temperature (which affects how well immune defenses work), and the ratio of ventilation to occupancy (which determines how concentrated the shared air becomes).
Stop reacting. Start optimizing.
Gain complete visibility into your building operations, eliminate budget surprises,and transition from "firefighting" to high-performance management.

What do the risk levels mean?
The Airthings Virus Risk Indicator combines these signals into a single 1–10 scoreso you can see where conditions favor transmission and act before it spreads.
1-4
Status: This is normal
Conditions don't favor airborne transmission
Recommended action
Maintain current ventilation, occupancy, and humidity
5-7
Status: Take action
One or more factors are pushing risk upward
Recommended action
Follow the dashboard's tailored suggestions to lower the score
8-10
Status: Warning
Conditions strongly favor transmission
Recommended action
Act immediately: ventilate, reduce occupancy, adjust humidity

The four factors that drive airborne virus risk
The Virus Risk Indicator combines four environmental factors (each backed by peer-reviewed research) into a single 1–10 score that's updated in real time.
FACTOR 1
Virus survival
How long airborne microdroplets remain viable in the air. Survival times shift dramatically with humidity and temperature. Viruses live longer in cold, dry air than in warm, moderately humid conditions.
FACTOR 2
Ventilation
How much fresh outdoor air is diluting the indoor air. Higher ventilation rates remove contaminated air faster; recirculation without filtration just moves the same air around.
FACTOR 3
Room occupancy
How many people are sharing the air, and how densely. More occupants in a fixed volume means more shared exhaled air and a higher concentration of any airborne pathogens being released.
FACTOR 4
Immune system
How well the body's airway barriers function in current conditions. Low humidity and cold air reduce mucus barrier function, making infection more likely even at the same airborne dose.
Why monitor virus risk?
Airborne virus risk isn't visible, but it's measurable through the environmental conditions that drive it. Monitoring those conditions gives building operators three things they can't get from cleaning protocols or distancing rules alone
