Did you know that clean air improves students’ academic performance?

Back arrow Back

There has been a lot of talk about air quality in schools recently due to covid. Less has been said about the connection between air and academic results. A 2020 research study shows that increasing ventilation rates from 2 liters per second to 7.5 l/s improves students’ national exam results by 5%.

The 2020 study measured elementary and middle school students’ ability to perform arithmetic calculations, language-based reading and comprehension tasks, and psychological tests that assessed concentration, memory, and reaction speed. Air quality was based on CO2, or carbon dioxide gas indicated in ppm (parts per million) in the air. If the CO2 content in classrooms is reduced from 2100 to 900 ppm, the speed of solving tasks increases by 12% and accuracy by 2%. Reducing CO2 concentrations from 2,400 ppm to 900 ppm can improve scores on state tests and exams by 5%, and reducing CO2 from 4,200 ppm to 1,000 ppm increases children’s daily school attendance by 2.5%.

Excessively high carbon dioxide levels due to insufficient ventilation reduce students’ attention, memory, concentration, reaction speed, and the frequency of going to school. The same connection also applies in the home environment because a lot of time is spent on studies at home. Therefore, if you want your child to have better grades at school, choose a home ventilation device that automatically increases the amount of air when the CO2 level rises.

Human exhaled air contains about 4% CO2, but outdoor air contains 0.03-0.04%, so indoor air contains approximately 100 times more CO2 than outdoor air. A person notices the increase of CO2 in the air only when he has already developed fatigue, sleepiness, and a sluggish feeling. Therefore, the simplest solution is a ventilation device that measures the CO2 level in the air and automatically increases the air volume when it rises. 

The level of CO2 in the air should be evaluated as follows: 

  • good quality is between 400 and 800 ppm
  • medium quality 1000 – 1600 ppm
  • bad quality over 1600 ppm

And the last one is the limit from which air quality harms humans. 

Our ventilation provides significant energy savings, as the ventilation only works when needed because of the integrated high-tech sensors in our units. So – if you want your child to have better grades at school, choose a home ventilation device that automatically increases the amount of air when the CO2 level rises. You can select the ventilation device suitable for the size of your home here.
