Indoor air quality monitors for schools: Everything to know
10,000+ organizations worldwide trust HALO
Table of Contents
Indoor air quality (IAQ) analyzes how harmful matter is inside an enclosed environment. Many know that the air we breathe outside potentially contains pollutants that can harm our health. However, those safety risks grow when we are inside buildings.
Environmental Protection Agency (EPA) studies report that pollutants can be up to 100 times more present indoors than outdoors. That raises concerns about students and teachers who spend most of their time inside buildings.
Implementing an indoor air quality monitor for schools is a solution as mitigating pollutants becomes more challenging. This guide will explain the critical role IAQ monitoring plays in student welfare and how to choose devices to integrate into your facilities.
The importance of indoor air quality monitors for schools
Studies across the United States continue to find a correlation between academic performance and indoor air quality. Reports show that the better the internal environment, the higher the return of respectable student results.
There are key areas that highlight the importance of indoor air quality in schools, including:
- Student and staff health – Learning environments are optimal when everyone attending the institution has good health.
- Student concentration – Poor indoor air quality can lead to lapses in concentration; for example if a classroom has inadequate ventilation, it can cause increased heart rates and nausea.
- Regulatory compliance – Many state regulations require indoor air quality monitors to help provide an optimal learning space for students.
- Comfortable learning environment – Teachers and students can focus on education and studying when the school faces environmental issues.
- Academic improvement – Schools with better indoor air quality have students who tend to perform better academically.
- Increased attendance – Students will be more encouraged to attend their classes when the indoor air quality is comfortable.
Threats to indoor air quality in schools
Indoor air quality is essential to schools, but it faces threats from various sources. Below are the leading challenges that educational institutions face:
Outdated HVAC systems
Heating, ventilation and air conditioning (HVAC) systems inside schools are primarily responsible for their air quality. However, many of the appliances in education environments are outdated.
Outdated HVAC systems can cause considerable issues with indoor air quality, such as poor ventilation, extreme internal temperatures and lack of air filtration. Older appliances are also prone to failure, posing more of a threat to students and increasing the school’s costs.
Old school buildings
Many school buildings in the U.S. date back decades, meaning they may not have the infrastructure to improve indoor air quality. Older constructions may not address the challenges faced by today’s climate, such as better insulation or ventilation.
High spread of germs
Schools are structures with a highly concentrated number of people inside, which can increase the likelihood of germ transmission. Poor indoor air quality, such as extreme temperatures and humidity, can multiply the spread of germs further, causing more illnesses among students and teachers.
Many conditions often reported in schools include allergies, asthma, respiratory infections, headaches and fatigue. These can be a result of poor air quality inside the facilities.
Air pollution
A study from the National Library of Medicine suggests that there’s concern about unhealthy levels of air pollution finding their way into schools. Increased exposure to nitrogen dioxide increases the risk of long-term health effects for students.
Student behavior
Student behaviors such as smoking and vaping in schools could contribute to overall poor air quality. Not taking action against the activity could increase the number of students doing the same, worsening indoor air quality.
Lack of funding
When schools face budget constraints, they must dedicate finances to education priorities such as supplies and teachers. Many will lack the funding to make the necessary improvements to tackle air quality challenges.
What to look for in an IAQ monitor
There are many features to consider when evaluating new or upgraded indoor air quality monitoring systems for your school. You’ll want devices that can accurately detect harmful matter, swiftly notify administrators of events and produce reports that can help with school decision-making.
Use the information below to understand what to look for in an IAQ monitor for schools.
Comprehensive range of detection
The best indoor air quality monitor for schools will have comprehensive detection capabilities to identify a broad spectrum of matter. Improving the environmental conditions inside means that devices should target some of the most common harmful substances, including:
- Volatile organic compounds (VOCs) – VOCs are potentially harmful human-made chemical compounds with high vapor pressure, including vape smoke and cleaning products.
- Carbon monoxide(CO) – An odorless, poisonous gas emitted from water heaters and boilers that can make students ill if exposed.
- Carbon dioxide(CO2) – A gas exhaled and airborne, possibly warming the area to uncomfortable temperatures if many students are in a classroom.
- Particulate matter – Contains microscopic solids or liquids from matter like smoke or soot, posing a health risk to teachers and students if inhaled.
- Temperature and humidity – High temperatures and humidity inside a school are the growing conditions for mold and mildew, which can damage buildings and cause serious illnesses.
- Nitrogen dioxide(NO2) – NO2 pollutants come from outside fuels that can enter the ventilation system, especially in an urban school environment.
- Nicotine and THC – Nicotine and THC come from tobacco and marijuana products that, when smoked, can contaminate the air.
Remote/cloud management
High-quality IAQ monitors have remote capabilities, with data accessible from external devices and stored in the cloud for further processing. As educational institutions become multi-facility establishments, administrators can benefit from remote detection capabilities with real-time notifications of unusual activity.
Integration with other systems
Integrating the technology with existing security systems is a key consideration for the best IAQ monitors for schools. Advanced devices can help improve your air quality detection abilities in parallel with other safety hardware and software.
Scalability
Growth in schools and education centers continues to rise, including the number of enrolled students and facilities to manage. Advanced indoor air quality systems should scale according to the school’s needs.
Tamper-proof/durability
Tampering with and obstructing IAQ monitors is a growing concern among school administrators as students attempt to hide smoking or vaping activities in schools. Ensuring your device is tamper-proof and durable can help facilitate a safer environment in all building areas.
Detection accuracy/sensitivity
An advanced IAQ sensor for schools will have various sensors that improve pollutant detection accuracy. Considering the possible range of harmful substances inside schools, the best devices will be able to accurately detect a broad spectrum of matter, such as those mentioned above.
Analytics/reports
Collected air quality data can help give administrators insights into the school’s state. Smart IAQ monitors can collect and analyze pollutant exposure patterns, creating reports supporting the improvement of the building’s internal environment.
