In a comprehensive global study conducted in 2017, the World Health Organisation estimates that indoor and outdoor air pollution causes around 6.5 million premature deaths annually.  Out of these deaths, China and India accounted for almost half of the numbers. 

China’s air pollution has long been in a global spotlight and highly criticized. However, a newer and more serious battleground has emerged as the indoor air quality deteriorates due to PM2.5 particles entering the space because of poor insulations and high levels of formaldehyde emitted by poor building materials. This is an imperative health threat as most people spend 90% of their time indoors.

Occupants of high air quality buildings were found to have higher cognitive function, fewer symptoms of sickness and better sleep quality. The rise in public awareness on how pollution is affecting public health has prompted many businesses and building managers to install air filters and air quality monitors in the indoor spaces. This is so as to meet the stringent requirements from International Well Building Institute (meeting 15 µg/m3 [PM2.5] in the ambient air). 

With the advancement of technology, consumers are empowered with greater knowledge about air quality using a plethora of apps and affordable monitors. This alters consumer behaviors where the air quality of a space could be a determining factor in making decisions on the hotel they want to reside in or the cafe to have a meal in. 

During this unprecedented time, we are staying indoors more than ever. It is therefore essential to keep our indoor air clean for a higher quality of living.
