Indoor Air Quality Infographic / 15 07 2021

Poor air quality can cause adverse health effects such as allergies, respiratory illnesses, damages to the cardiovascular system and others. Considering that on average humans spend more than 90% of their time indoors, it’s essential to guarantee fresh, pollutant-free air to minimise air pollution exposure risks. Airscan team prepared an infographic with all the adverse effects of poor indoor air quality on humans reported by the World Health Organisation and Environmental Protection Agency in the last few years.


Based on the latest reports from public health institutions indoor air can be up to 5 times worse comparing to outdoor fresh air. Indoor air harbour a wide range of odourless and invisible pollutants that can result in various health problems

Symptoms of air pollution exposure can vary from simple irritations of the respiration system, skin and eyes to premature death. In 2019 the World Health Organisation reported that more than 7 million premature deaths are caused by polluted air annually. Airborne particles, diesel exhaust, carbon monoxide, dust, smoke, ozone, nitrogen oxides and pollen are one of the most common pollutants present indoors. Moreover, building materials and house utilities can release a wide range of toxic chemicals known as volatile organic compounds. These compounds are harmful and can result in sick building syndrome development at long term exposure. Finally, COVID – 19 pandemic showed the importance of biological pollutants management in indoor environments.


An effective air quality management plan includes several steps to get pure fresh air indoors. The plan consists of continuous air quality monitoring, identification and elimination of pollution sources as well as installation of air purification units. The selection of air cleaners is a responsible step that should be ideally discussed with professional experts. It is strongly recommended to avoid the usage of dubious devices that have no certification license. Such devices might not clean indoor air but make it even worst. For instance, some of the devices constantly generate Ozone gas as a byproduct of purification.

In conclusion, Airscan team will prepare a description of pollutants and purification technologies that can be used to capture them in the following articles.
