Improving Indoor Air Quality In America's Schools

Jocelyn M. Miner

Indoor Air Quality Matters - Especially for Children

Most people understand how poor outdoor air quality can cause issues for our health, but there is less focus on how indoor air quality can be even more impactful. Humans-- especially children-- spend most of their time indoors, so indoor air quality (IAQ) is an area of concern in the development of respiratory issues (Breysse et al., 2010).

During the COVID-19 pandemic, it's been made more salient that indoor air quality in our schools must be improved. With many children back to in-person schools but still awaiting vaccination against COVID-19, efforts are being made to mitigate air quality concerns (American Academy of Pediatrics, 2021). Along with universal masking, proper air flow and ventilation are essential in the mitigation of COVID-19 spread, as well as the overall health of children (Centers for Disease Control and Prevention, 2021).

Aside from COVID-19, the reduction of allergens and toxins in classrooms can help prevent the development of asthma and other problems associated with poor air quality (Breysse et al., 2010).


It is particularly important to address the issue for children in schools, for several reasons:

  • Children spend up to 90% of their time indoors (Breysse et al., 2010).

  • Children breathe 2-3 times more breaths per minute than adults, taking in more pollution (Gough, 2019).

  • Children’s lungs and blood-brain barrier are not yet fully developed (Gough, 2019).

Impacts of Poor Indoor Air Quality in Schools

The United States Environmental Protection Agency (2020) has identified some impacts of poor indoor air quality for schools:


  • Poor student attendance

  • School closures

  • Potential for long-term health problems among children and staff

  • Expensive repairs

  • Poor learning environment

  • Liability issues

  • High expenses


Being proactive about replacing old HVAC systems and improving indoor air quality can save money and prevent the above (U.S. Environmental Protection Agency, 2020).

Poor Indoor Air Quality Disproportionately Impacts Students Experiencing Poverty, Students of Color, and Girls

Households with lower socioeconomic status were found to experience greater likelihood of poor indoor air quality than more affluent households -- and children are worse off than adults when it comes to poor health outcomes from air quality issues (Ferguson et al, 2020). With such a high percentage of American students considered low-Income, the scope of the problem is massive.

Racial Disparities of Asthma Prevalence

Not all groups are equally impacted by asthma and poor indoor air quality-- some are more vulnerable than others. The data graph on the left shows that Black women and girls have the highest prevalence for asthma in the United States (Centers for Disease Control and Prevention, 2019). Asthma can be worsened by indoor air pollutants (Breysse et al, 2010).

Air Ventilation in Schools

Funding for Schools

In October 2020, New Mexico senator Martin Heinrich introduced the Keeping Schools Safe Act, which would allot $1 billion in Department of Education grants to fund upgrades that would support the improvement of indoor air quality in elementary and secondary schools (Beverly, 2020). Not only would this bill--if passed-- give schools with the ability to purchase and install new equipment, it would also provide schools with guidance on how to figure out which upgrades are needed to begin with. The bill would help support local measures (which vary from place to place) that have been taken to mitigate the spread of COVID-19 through improvement of air quality in schools.

In 2021, the Department of Education released the American Rescue Plan, which provides infrastructure funding for schools and universities that can be used to improve indoor air quality. President Biden's Build Back Better plan would further support these efforts (US Department of Education, 2021).

A bipartisan majority supported the American Rescue Plan, but the Build Back Better plan and Keeping Schools Safe Act are facing more pushback amid inflation concerns (Kapur & Tsirkin, 2021). This situation is still unfolding; time will tell whether these initiatives are put into place.

How is the Funding Being Used?

American Rescue Plan funding is available NOW for all kinds of infrastructure improvements! Not only will this help with COVID-19 mitigation, but will have carry-over benefits for reducing the likelihood of other poor health outcomes (US Department of Education, 2021).
