How To Improve Indoor Air Quality In Schools

An integrated approach to air quality in schools beyond COVID-19

Over the last few years, issues that affect the health of our school children such as nutrition and exercise have been receiving a great deal of focus,1 but the importance of providing quality indoor air to avoid illness, improve health and wellbeing, the ability to learn and thrive, has only recently received the attention it deserves.

There are many reasons why indoor air quality is important for students and teachers alike in school settings. The quality of the air affects students’ health and comfort, their ability to learn, and the levels of absenteeism.

It’s reported that 1 in 10 Australian children suffer from asthma, a condition made worse by poor indoor air quality.

In recent years, comparative risk studies performed by EPA’s Science Advisory Board (SAB) in the USA have consistently ranked indoor air pollution among the top five environmental risks to public health. Good indoor air quality is an important component of a healthy indoor environment and can help schools reach their primary goal of educating children4.

COVID-19 saw many students learning from home for months at a time, and the knowledge that airborne pathogens are largely responsible for the virus’s transmission became widely known. The chance of outbreaks from school communities became more of a concern.

As students return to schooling away from home, the knowledge of indoor air quality and how to clean, ventilate and monitor the air is becoming an imperative for old and new school buildings alike.

Our recommendation is always to look at an integrated approach. What are the current systems for air quality and ventilation in the school? How can they be improved?

How Can Schools Create Healthy Buildings?

Although disinfecting and cleaning surfaces will always be part of the protocol in any school, according to a article recently published,5 current transmission of COVID-19 is not as much through surfaces but through aerosol and airborne pathogens. In the early days of the global pandemic it was thought that the virus was transmitted via surface contamination (the cost of deep cleaning across the US market is thought to have jumped by 30% in 2020), but

“Now that it is agreed that the virus transmits through the air, in both large and small droplets, efforts to prevent spread should focus on improving ventilation or installing rigorously tested air purifiers.” (

Airborne transmission means poor ventilation is likely to contribute to infections,so minimising airborne transmission is critical.

Think of quality indoor air as a system. We recommend analysing and measuring the quality of the air as a logical first step to improving how current systems of cleaning and ventilation are taking place, and to highlight where improvements can be made. Ongoing monitoring is then critical to maintain any practices or systems that are in place.

An integrated and whole building solution works best to analyse, clean and continuously monitor indoor air quality. Simple updates to current systems could include a change of cleaning schedule, or perhaps more regularly changing filters. These are all budget conscious actions schools can take to have a big impact on the health and wellbeing of the teachers, administrators and students alike.
