Beijing: Chinese tourists from smoggy and pollution-hit cities are buying fresh air cans for about USD 4.5 at an ongoing trade expo in Hainan province.
About 300 cans of fresh air from south China's Hainan province were sold at seaside tourism resort.
Selling at a discount price of 29 yuan (about USD 4.5), the cans of air have sparked a buying spree at the 2016 Hainan International Tourism Trade Expo, state-run Xinhua news agency reported.
It was bottled in Bawangling, Changjiang County of southwest Hainan, where the forest coverage is up to 98 per cent.
Bawangling's average negative oxygen ions per cubic centimeter reach as high as 6,000, six times the standard of clean air stated by the World Health Organisation.
"The first batch of 300 cans was all sold out, and it will start selling to the public in two months," Liu Jin, deputy county chief of Changjiang at the expo, who introduced the product said.
Companies are already in negotiation to further research and development for larger sizes and different applications, Liu said.
In December, Beijing issued its first ever red alert due to poor air quality, closing schools and restricting traffic. Last month, an enterprising young British businessman sold bottles of "cool" British country air to monied Chinese in pollution-hit cities at 80 pounds (USD 115) per bottle.
