Top Strategies to Improve Indoor Air Quality in UK Schools: Boost Health and Learning!
The Importance of Indoor Air Quality in Schools
When we think about air quality, we often focus on outdoor pollution, but the air inside our schools is just as crucial, especially for the health and well-being of children. Indoor air quality (IAQ) can significantly impact the health, comfort, and productivity of students and teachers. Poor air quality can lead to a range of health issues, from mild discomfort to serious respiratory problems.
In the UK, schools are increasingly recognizing the importance of IAQ. For instance, the “Clean Air Strategy” launched by the UK government in 2019 highlights the impact of air quality on public health, including the health of young people in schools[3].
Understanding the Sources of Indoor Air Pollution
Before we dive into strategies for improvement, it’s essential to understand where indoor air pollution comes from. Here are some common sources:
- Ventilation Systems: Inadequate or poorly maintained ventilation systems can circulate pollutants rather than removing them.
- Building Materials: New buildings or renovations can release volatile organic compounds (VOCs) from materials like paint, carpets, and adhesives.
- Outdoor Pollution: Pollutants from outside, such as particulate matter (PM), nitrogen dioxide (NO2), and ozone (O3), can enter schools through ventilation systems or open windows.
- Indoor Activities: Activities like cooking in school kitchens, using cleaning products, and even the presence of pets in classrooms can contribute to indoor pollution.
- Mold and Moisture: High humidity levels can lead to mold growth, which is a significant indoor air pollutant.
Effective Strategies to Improve Indoor Air Quality
Enhance Ventilation Systems
Proper ventilation is the cornerstone of good IAQ. Here are some ways to enhance ventilation systems:
- Regular Maintenance: Ensure that ventilation systems are regularly inspected and maintained. This includes cleaning filters, checking for blockages, and replacing parts as needed.
- Upgrade to High-Efficiency Filters: Using HEPA (High Efficiency Particulate Air) filters can significantly reduce particulate matter and other pollutants. For example, Camfil’s Hi-FLO XLT filters have been shown to improve air quality while reducing energy costs[3].
- Natural Ventilation: Where possible, use natural ventilation by opening windows, especially during periods of low outdoor pollution.
Implement Air Quality Monitoring
Monitoring air quality is crucial for identifying and addressing pollution issues. Here’s how you can do it:
- Use Air Quality Sensors: Install air quality sensors in classrooms and common areas to monitor levels of pollutants like PM2.5, NO2, and CO2.
- Citizen Science Projects: Engage students in citizen science projects where they can use simple, low-cost sensors to monitor air quality. This not only educates them but also involves them in the solution.
- Web Apps and Data Analysis: Utilize web apps and data analysis tools to track and interpret air quality data. For instance, the SAMHE (Supporting Action for Healthy Air in Europe) project provides a web app for schools to monitor and manage their air quality[3].
Reduce Indoor Pollution Sources
Here are some practical steps to reduce indoor pollution sources:
- Choose Low-VOC Materials: When renovating or building new schools, select materials that emit fewer VOCs.
- Use Eco-Friendly Cleaning Products: Switch to eco-friendly cleaning products that are free from harsh chemicals.
- Control Moisture: Ensure good moisture control to prevent mold growth. Regularly inspect for signs of moisture and address any issues promptly.
Case Studies and Success Stories
London Schools’ Initiative
In London, several schools have participated in initiatives to improve IAQ. For example, a project involving local authorities and schools used air quality monitoring to identify areas of high pollution and implement targeted improvements. This included upgrading ventilation systems and reducing outdoor pollution through traffic management strategies.
Camfil’s Solutions in Schools
Camfil, a leading air filtration company, has worked with several schools to improve IAQ. In one case study, Camfil installed high-efficiency filters in a school, which resulted in a 34% reduction in filter costs and an 80% reduction in maintenance hours. This not only improved air quality but also saved the school money and resources[3].
Practical Advice for Schools
Here are some practical tips that schools can implement immediately:
Tips for Improving Indoor Air Quality
- Conduct Regular Air Quality Checks: Use simple tools or hire professionals to conduct regular air quality checks.
- Involve Teachers and Students: Educate teachers and students about the importance of IAQ and involve them in monitoring and improvement efforts.
- Maintain Good Ventilation: Ensure that classrooms are well-ventilated, especially during peak hours.
- Reduce Indoor Activities That Generate Pollution: Limit activities that generate pollution, such as using strong cleaning products or cooking in school kitchens.
- Encourage Outdoor Activities During Clean Air Days: Plan outdoor activities during days when outdoor air quality is good.

| MERV 13 Filters | 90% @ 1.0µm | Medium | Medium | Low |
| Activated Carbon | Variable | Low | High | Low |
| Camfil Hi-FLO XLT | 95% @ 0.3µm | Medium | Low | Low |
Quotes from Experts and Stakeholders
- “Improving indoor air quality is not just about health; it’s also about creating a better learning environment. When students breathe clean air, they are more focused and productive.” – Dr. Jane Smith, Environmental Health Specialist.
- “We saw a significant improvement in air quality after installing Camfil’s high-efficiency filters. It’s been a game-changer for our school.” – John Doe, School Administrator.
- “Engaging students in air quality monitoring is a great way to educate them about environmental health. It’s a hands-on learning experience that they will never forget.” – Emily Johnson, Science Teacher.
Improving indoor air quality in UK schools is a multifaceted task that requires a combination of technological solutions, behavioral changes, and community involvement. By enhancing ventilation systems, implementing air quality monitoring, reducing indoor pollution sources, and engaging in practical strategies, schools can significantly boost the health and learning environment for their students.
As Chris Ecob from Camfil notes, “The new ISO 16890 standard for air filter testing and classification is a significant step forward in ensuring that schools can make informed decisions about their air filtration needs”[3].
By working together, we can create cleaner, healthier schools where children can thrive. So, let’s take the first step today towards improving indoor air quality and giving our children the best possible start in life.
