Professor Prashant Kumar
In research titled "Investigation of air pollution mitigation measures, ventilation and indoor air quality at three schools in London", Professor Kumar and his team demonstrated how simple measures could make a significant difference to tens of thousands of children in the UK. This research can be found in the Journal of Atmospheric Environment.
Air purifiers in classrooms cut PM by up to 57%
Green screens reduced playground PM by up to 44%
School streets reduced outdoor PM by up to 36%
Professor Kumar is Founding Director of The Global Centre for Clean Air Research located just down the road from us in Hampshire. Their work has consistently shown the clear advantages of air purifiers in classrooms throughout the height of the pandemic and onwards.
Professor Kumar is one of the most highly cited scientists in his field and is a leading researcher on the impact air pollution has on the health of children and young people. The California Air Resources Board has recognised Professor Kumar with the prestigious Haagan-Smit Clean Air Award, widely considered to be the "Nobel Prize" in air quality achievement.
We are honored to have met, and are grateful for his support.

Professor Cath Noakes OBE
Professor Noakes discusses the impact of air quality and air cleaners on children’s education, including her research that shows air cleaners reduce absenteeism.
Professor of Environmental Engineering for Buildings at the University of Leeds, Professor Noakes leads research on ventilation and indoor air quality. She has worked on multiple national and international projects and served as an advisor to the UK government on the COVID-19 pandemic.
Air purifiers in classrooms cut illness absence by over 20%

The Lancet
A report by the The Lancet COVID-19 Commission Task Force on Safe Work, Safe School, and Safe Travel. The report evidences the benefits of improved air quality in schools, including:
Improved test scores; cognition; math, reading and science scores
Reduced asthma symptoms; respiratory symptoms; missed school days;
child absenteeism; illness absence

SAMHE Programme
The Schools Air Quality Monitoring For Health And Education Programme (SAMHE) was a collaboration between five UK universities (University of Cambridge, Imperial College London, University of York (through the Stockholm Environment Institute's York centre), University of Surrey, University of Leeds) and the UK Health Security Agency (UKHSA).
Funding for the SAMHE project was provided by the Department for Education and Engineering and Physical Sciences Research Council (EPSRC).
SAMHE produced an evidence synthesis of their work with recommendations for policy and practice, titled Improving Air Quality In Schools.
"School Air Quality Guidance Should Be Updated To Focus On Providing Good Ventilation And Good Air Quality"

Day Care Centres
Research provides evidence to support the implementation of air cleaners in daycare centres as an effective and cost-effective strategy for mitigating the spread of respiratory infections among children.

Distinguished Professor Jose-Luis Jimenez
Hosted by the US Environmental Protection Agency Indoor Environments Division, this webinar features presentations on the health benefits vs disbenefits from indoor air cleaners.
Professor Jimenez is Expert Advisor to Safe Air Schools UK. Further detail about his work can be found on our Expert Advisor page.
