COVID-19 can be spread by breathing in air exhaled by another person. High CO2 levels in the environment means a higher % of the air you breathe is shared with other people which leads to a higher exposure risk.
COVID-19 is spread in tiny, invisible droplets called aerosols that are expelled when infected people breathe out, speak or sing
The more people in a closed space, the greater the risk of infection
Making sure spaces are well-ventilated is key to reducing the spread of the virus
CO2 monitors show which areas need better ventilation
"If you are sharing air, the lower the CO2, the lower risk of infection.”

The smart choice
The most effective way to tackle uncertainty is with science.
Tether’s COVID Care CO2 monitoring offers live data, allowing you to make educated, safe decisions.
Get real-time risk alerts and effect quick, safe change.
Classrooms in England are to be fitted with CO2 monitors when state schools and colleges reopen after the summer holidays, in an effort to improve ventilation and combat the spread of Covid... Read more
How COVID Care works
Scan to activate and stick the monitoring device to the wall of your premises
Your device will scan the air in real-time, tracking the CO2 levels in the space
You will be alerted well ahead of time if CO2 is rising, allowing you to increase ventilation and reduce the transmission risk
Your customers feel safe and happy knowing and being able to see in real-time they are at a low risk
Looking after our communities
Reduce the anxiety of close contact after months of social distancing.
Teachers, parents, and learners are able to monitor live, real-time CO2 levels on public display or by scanning a QR code.
Provide a much-needed additional layer of COVID-19 protection for our young and unvaccinated.
“Schools are an important part of the infrastructure of communities, as they provide safe and supportive learning environments for students, employ teachers and other staff, and enable parents, guardians, and caregivers to work.”

Knowledge is power
Data is recorded and stored to be able to track trends and preempt disruption.
Keeping CO2 levels down mitigates the risk of having to close frequently for exposure to outbreak and subsequent deep cleaning.
We may not be able to control the virus, but we can go a long way to preventing its spread.
Power - at your fingertips

How many monitoring devices will I need for my space?
How do you stick the monitoring device to the wall?
Will I have enough warning time between risk zones to take action?
What if I don't want to publicly display the CO2 levels to my customer?
How do we make sure our schools are safe?
By monitoring the air our teachers and children are breathing.

“People infected with coronavirus can spread it around a room in tiny airborne droplets called "aerosols" when they breathe out, speak, shout or sing.
These aerosols build up indoors, especially when a place is crowded or there is poor ventilation, and the longer you are surrounded by them, the more chance you have of breathing them in.
Unfortunately, the aerosols are so small you can't see them, which is where the CO2 meters come in.
In addition to aerosols, we also breathe out CO2 — a byproduct of respiration — which builds up in the air unless a space is ventilated.
And this CO2 is easier to measure than the aerosols or virus particles themselves.
So the level of CO2 in a space can be used as proxy for the possible risk of exposure to coronavirus.”
