It is that time of the year when Shanghai outside air is expected to soar at its highest.


In addition to the regular maintenance of our air purifiers and air-conditioning vents, SEIPS is excited to acquire the services of an indoor air monitoring company, GAMS, to monitor the school’s indoor air readings as part of SEIPS’s long-term sustainable solutions.


GAMS uses a commercial grade sensor and device that measures current and live indoor air monitoring, which assists the school in quick identification of air issues, if present.


Here are some significant information to learn about air quality readings:

indoor air quality guidelines

AQI stands for Air Quality Index, it is a number used to communicate how polluted the outdoor air is. In the US and China, the AQI is based on the measures of 6 atmospheric pollutants: sulfur dioxide (SO2), nitrogen dioxide (NO2), particulate matter smaller than 10 micrograms (PM10) and smaller than 2.5 micrograms (PM2.5), carbon monoxide (CO), and ozone (O3).


Indoor air quality is concerned with particulate matter (PM), carbon dioxide (CO2) and total volatile compounds (TVOC). These 3 components affect the safety of indoor air if not monitored and controlled.


  • PM is the term for particles found in the air, including dust, dirt, soot, smoke, and liquid droplets. Some particles are so small that individually they can only be seen with an electron microscope.
  • CO2 is a colorless, odorless gas. In the environment, people exhale CO2 which contributes to CO2 levels in the air. A build up of carbon dioxide in an indoor space affects the productivity and comfort of occupants.
  • TVOC includes a very wide range of organic compounds that can be emitted from building materials and products.


Below are guidelines for safe indoor readings that have been compiled using the standards of WHO, EPA, ASHRAE and other leading institutions on safe indoor air quality. The school will follow these guidelines set by GAMS. These guidelines are what the school will adhere to for measuring safe indoor air quality for the school.





GAMS will also provide consultation on measures that could be enlisted, to further improve the indoor air quality as deemed necessary.


Prior to the above measures, SEIPS already had policies in place to ensure that the school is doing its best to tackle the poor outside air quality. Daily classroom indoor air readings are taken, and classroom windows are closed and remain closed should the outside air quality reflect poor readings. These policies are regularly revisited and adjusted as required, in light of changes and developments outside the school’s control.


SEIPS continues to provide the most sufficient efforts it could, to ensure that our children remain healthy and happy in the school. We hope to continue working in partnership with our families in the fight against bad air.
