Indoor pollution levels can be two to five times higher than outdoors (and even 100 times in severe cases). More than enough reason to be concerned about students who spend extended periods of time in their classrooms. There is now a need fora room air purifier every place humans exist in tier-1 cities.
Next, you will discover what the main causes of air pollution are and what solutions can be implemented in educational spaces.
What are the main causes of air pollution?
The first source of contamination is the one that comes from the outside, entering the rooms through windows, doors or ventilation in poor condition.However, eliminating natural or artificial ventilation also has its consequences.
In fact, the concentrations of CO2 (carbon dioxide) increase in a closed space, reducing oxygen and increasing the rate of aerial contagion of diseases, such as the flu, measles, tuberculosis, and COVID-19, among others.Unventilated classrooms can harbour CO2 concentrations ranging from 1,500 ppm to 3,000 ppm.These measurements are worrying if we take into account that the value that is considered acceptable in a room is below 500 ppm on the outside, which is equivalent to a maximum of 900 ppm.
On the other hand, special attention must be paid to the temperature and humidity present in the interior school space, since they are among the factors that affect air quality.
Hazardous Air Pollutants
Some dangerous air pollutants are dust, cleaning and disinfectant items, gas leaks or construction debris near the educational establishment.
Fungi, bacteria, viruses, spores from bird faeces and mites can also be found.One of the viruses is COVID-19. At the start of the pandemic, the main cause of the spread was thought to be coughing or sneezing.
However, it is now known that activities such as running or shouting in closed spaces without the presence of ventilation considerably increase the risk of contagion (speaking loudly releases 50 times more virus-laden particles into the air than keeping silent).Furthermore, in educational institutes, young people may be more sensitive to pollution than adults.
For what reason? They generally breathe more air and drink more fluids relative to their body weight.It is for this reason that exposure to indoor air pollution almost doubles the risk of respiratory diseases, such as pneumonia, during childhood.
What is an air purifier?
A practical solution to avoid the threats present in closed spaces in colleges and schools is to improve ventilation, and for this, installing an air cooler purifier is an effective solution.
What are they about? They are equipment designed to eliminate harmful gases, particles and polluting elements suspended in the air of closed spaces.
It achieves this thanks to the fact that it is equipped with a HEPA filter, a carbon filter and a multi-layer filter.Thanks to these filters, HEPA air purifiers can eliminate more than 99% of particles in the environment, which include:
- mould spores.
- Smoke particles.
Why is it important to integrate it into educational establishments?
Using an air cooler purifier in an enclosed space greatly decreases the concentration of ultrafine particles in the air.In this way, conditions in children, such as cough, eye irritation, allergic reactions and asthma, can be avoided. This also decreases the chances of contagion by the new coronavirus and other diseases.
In this way, we will be able to provide a suitable space where our children, adolescents and teaching staff can develop in a healthy way and can focus on their studies with the safety and hygiene they need.
