Clean Air AM and PM......

New high-performance HEPA filters were fitted into the CleanFlow positive pressure system at the Sports Hall by Charlie Thomson from Environment Assured. The new set of filters will ensure that the Sports Hall maintains its near-zero PM2.5 air quality -in case the smoky season lasts a bit longer.

It was great to see how well the system kept down the PM2.5 in healthy levels at  CMAC volleyball tournament last week. The sports Hall is monitored 24/7 and the air quality is also displayed on the Prem website: https://ptis.ac.th/aqi-at-prem/
With the increased Covid-19 cases, Environment Assured also optimised the fresh air ventilation inside the classrooms to meet recommendations of the US CDC and German Environment Agency for CO2 levels in classrooms.
