Study and solution of the transmission of coronavirus disease (Covid19) indoors.

The latest research on coronavirus disease (#COVID19), is showing that most infections can occur in closed, poorly ventilated spaces, through aerosols.
“Covid19 is transmitted through aerosols: it is time to act, we have enough evidence”

See source:

Outbreaks of super propagation, where one person infects many others, occur in crowded bars and social gatherings, but not on beaches or in parks.

Researchers’ words: “The available evidence strongly supports aerosol transmission, and there are no strong arguments against it. We know that aerosols contain infectious viruses.”

The visual analogy of smoke can help guide risk assessment and our strategies for reducing risk. We only have to imagine that everyone else we meet is smoking, and that the goal is to breathe as little smoke as possible.

This gives us an estimate of the amount of “exhaled smoke” that has to be inhaled to become infected. Inhaling a little “smoke” here and there is usually not a problem, but inhaling a lot of “smoke” over a long period of time without a mask is risky.

Our solution to control this type of transmission

Given this new understanding of contagion, it is important to think about indoor air ventilation.

Focusing on the solution, we need to increase the amount of indoor air that is replaced by outdoor air. A good solution is to have windows open in buildings, but when temperatures drop, we need to ventilate much more efficiently to avoid heat, energy and money loss.

These investigations advise us that maintaining a level of CO2 in interiors below an established limit would make transmission through aerosols difficult, since CO2 is an indicator of how well ventilated a room is. And if there is little CO2 inside a room, there will be “little” amount of virus in this room.

Therefore, we have been working to develop an indoor solution that controls and analyzes air quality 24 hours a day, in an economic and safe way.

A solution that has temperature, humidity, CO2, people agglomeration, internet connection and artificial intelligence sensors. All this, to be able to show the analysis of any of the parameters under study. And based on this, to be able to make better decisions.


With this, we will allow the managers of indoor places where there is an influx of people (restaurants, celebrations, gyms, public places…), to know at all times how well ventilated they are.

There will be times in the year when opening the windows is not the most appropriate action, as well as using the centralized air. Knowing the best time to use them, can lead to savings in time, health and money.

In the following image, you can see how our device works. Not only will it take data, but it will be continuously analyzing it in order to draw conclusions in an effective way. Data collection such as low outside temperature, high inside humidity, and high CO2 index may need different action than if there is a high outside temperature, low inside humidity, and low CO2 index.

This data is stored in such a way that the user has a predictive tool throughout the time of its local and consult at any time, which could happen in the future.
