The quality of the air we breathe indoors is deeply intertwined with the air outside. As highlighted in The Impact of Outdoor Air Quality on Indoor Air and Your Options, outdoor air plays a critical role in diluting indoor pollutants and maintaining a healthy environment. However, when outdoor air is polluted, it can introduce harmful contaminants like nitrogen dioxide, particulate matter, and industrial emissions into our homes and workplaces. This underscores the importance of monitoring both indoor and outdoor air quality to make informed decisions about ventilation and air purification.
Hong Kong’s air quality is not the best.The recent South China Morning Post Article "Hong Kong’s average roadside nitrogen dioxide level exceeds WHO mark by 550%", paints a concerning picture. Despite a decline in overall pollutants, roadside nitrogen dioxide levels remain alarmingly high, far exceeding WHO guidelines. This highlights the urgent need for greener transportation solutions and better air quality management.
For those living in areas with poor outdoor air quality, strategies like energy-efficient mechanical ventilation, air purifiers, and filtered outdoor air intakes can help maintain healthier indoor environments. By staying informed and proactive, we can mitigate the impact of outdoor pollution on our indoor spaces.
