Most people worry about indoor air quality amidst the COVID-19 pandemic
A survey commissioned by Vaisala shows that people would feel safer with more data on indoor air quality. The survey, which included over 4,000 respondents in the USA, France, Germany, and Finland, was conducted in the summer of 2021, studying people’s concerns regarding indoor air during the COVID-19 pandemic. More than one third of the respondents are concerned about the indoor air quality in their place of work, and more than half said that concerns with indoor air quality impacts their motivation to visit public spaces. Around two thirds of respondents also said that these concerns impact their motivation to travel.

“Vaccination rates are high in the surveyed countries, but the survey revealed high levels of concern with air quality in indoor spaces. We believe this is because, intuitively, people understand that infection risk is higher in indoor spaces where people are in close proximity with each other, and where ventilation is insufficient,” says Anu Kätkä from Vaisala’s product management.
“When people spend too long in a poorly ventilated space, their exhaled breath causes carbon dioxide (CO2
) levels to rise. Higher levels of CO2 but importantly, monitoring CO2 high and better ventilation is required. By monitoring CO2 therefore provide the reassurance that the survey respondents need,” Kätkä explains.
Out of all the respondents, the Finns are the most confident about going back to work: 71% of Finnish respondents feel safe about returning to the workplace. 70% of French respondents feel safe about returning; 65% of American respondents, and just 55% of the German respondents.
50% of all respondents said that they would feel safer about returning to work with more information about indoor air quality. Indoor air quality can be monitored with instruments that measure, among other parameters, CO2
, humidity, and temperature. These parameters can be
used to automatically inform ventilation and building management systems so that indoor air quality can be optimized.
“Indoor air does not only affect exposure to airborne diseases but also employees’ energy levels, because exhaled breath increases CO2
levels which, in turn, increase drowsiness,” Kätkä continues.
The survey also studied people’s perception of indoor air quality in public spaces, such as shopping centers, sports facilities, and public transportation. Overall, people are more concerned about indoor air quality in public areas than at their place of work. 50% of all respondents would like more information in the workplace, whereas 60% would like more information on indoor air quality in public spaces.
The concern with indoor air quality in public spaces translates into a reluctance to travel, with 65% of respondents saying that concerns with indoor air quality in public places affect their motivation to travel.
Schools, shopping centers, restaurants, stations and airports all benefit from indoor air quality monitoring. Viruses travel faster in dry air, but humidity can make people feel unwell. It is therefore important to monitor and maintain optimal conditions, and to share the monitoring data with all stakeholders, including staff and members of the public.
Based on the survey results, indoor air quality is a concern in the mind of at least every third person, and more than half of all the respondents want more information and data on air quality inside those places where they spend time. This means that facility managers face important decisions.
“In recent years, many countries have implemented regulations concerning the monitoring of indoor air quality parameters such as CO2
. These regulations are designed to ensure optimal air quality, but in order to achieve this goal, accurate and science-based data is essential,” explains Kätkä.
Reliable measurement instruments perform a key role in decision making to prevent the spread of diseases and protect people’s health. The prerequisite for healthy indoor air is efficient ventilation and air conditioning that prevents diseases from spreading, keeps the mind clear, and ensures a healthy environment.
The survey was conducted between June 21, 2021 and July 11, 2021 together with the market research company Norstat in Finland, France, Germany, and the United States. The survey gathered approximately 1,000 respondents in each country, and the respondents included both men and women aged 18-65.
