As smog spreads across Southeast Asia, sales of oxygen tanks and air purifiers skyrocket.

The persistent haze that has blanketed large areas of Southeast Asia for months has forced school closures and led to a surge in respiratory illnesses. Many families are rushing to buy air purifiers to help maintain clean air indoors.

A spokesperson for the consumer electronics chain Courts told AFP : "Customers are increasingly concerned about indoor air quality and are actively seeking solutions to maintain a healthier and more comfortable living environment at home."
