Keep Omicron away from our students and staff – Replace the filters

To prevent and control coronavirus disease spreading in schools, Hong Kong government has announced the suspension of classes in kindergartens and primary schools from Friday through the Lunar New Year holiday.

Suspension will not relieve the concerns of parents and students. Hundreds of thousands of students will head back to school after CNY holiday. They are still facing the threats of Omicron and forced to accept the unsafe learning environment.

The ventilation systems in schools are the key to decide whether it is safe.

Why good ventilation is so important?

Someone who has coronavirus breathes out small particles (aerosols) of the virus. Adequate ventilation reduces how much virus is in the air, so it reduces the risk of breathing in the virus.

ASHRAE (American Society of Heating, Refrigerating, and Air-conditioning Engineers) reported in their journal of August 2020 that a high efficiency filter is effective in capturing airborne virus particles and hence reduce the risk of spread of viruses.

Research has shown that the particle size of the SARS-CoV-2 virus is around 0.1 µm (micrometer). However, the virus does not travel through the air by itself. Since it is human generated, the virus is trapped in respiratory droplets and droplet nuclei (dried respiratory droplets) that are predominantly 1 µm in size and larger.

The air you and your students're breathing indoors is dirtier than you think⚠️
