Prem’s Zero AQI classrooms

How Northern Thailand’s only four-programme IB world school is tackling pollution head-on

Professional schools understand that young people thrive and succeed when they have access to healthy environments, high quality educators and joyful learning. Prem made an early commitment to maintaining this ethos throughout the academic year, including minimising the impact of Chiang Mai’s notorious smoky season. One of the first schools in Chiang Mai to install industry-grade air purifiers into each classroom, train staff, implement air-quality policies and add 24/7, outside air quality sensors to the AQICN network, adhering to the far more stringent US AQI standard; this year, they plan to go even further.

With the 2019 smoky season being the worst in thirty years, and the potential for future seasons to have an increased impact on teaching and learning, a new Air Quality Committee set about ensuring that Prem’s teaching spaces would have the best air quality of all schools in Northern Thailand.

Installing additional purifiers, creating a dedicated network of more than 40 air quality sensors, implementing alert systems that inform key staff of AQI peaks and automated messaging to the parent community, the committee set about answering its final question: how do we ensure zero AQI in every teaching space, no matter how bad the outside air is?

By the time the smoke arrived in 2020, Prem School had trialed a new type of purification system, one that creates a positive pressure of fresh clean air inside classrooms thus preventing any dirty air from entering. The new system has achieved PM2.5 of ZERO aqi, on some of the worst days of the year and is thus significantly outperforming even the best air purifiers.

This autumn, Prem will be installing the system throughout our learning spaces, guaranteeing PM2.5 levels well under the strict WHO recommendation of 10 μg/m³. This ensures that we provide the healthiest of learning environments for our young people and our expert educators and provide maximum protection from both the smoke and any potential COVID transmission through fresh air ventilation.
