A Chinese firm is making brisk business selling cans of fresh air bottled in a forest in western China for 48 yuan (6.95 dollars).

According to reports by Shaanxi media, each bottle is good for two minutes of uninterrupted use.

From air-filter necklaces to anti-smog stockings, Chinese companies are touting innovative, if not odd, products to consumers worried about the quality of the air that they breathe.

“We set up a factory in Ningdong Forest Park in Shaanxi province and compress air directly into the bottle,” said Zhai Wenjun, sales manager at Sanqin Forest Industry, which is backed by the local Taibai Forestry Bureau.

“Consumers will feel like they are breathing in the forest,” Zhai said.

In spite of widespread criticism on China’s Twitter-like microblog Weibo, Shaanxi media reported that the first batch of Qinling Forest Oxygen-Enriched Air had been sold out.

“The air reminds me of the forest,” said a user on Taobao, China’s most popular consumer-to-consumer online shopping website, adding that the price is “reasonable.”

Zhai refused to disclose sales data to Reuters, saying it is a business secret.

“As the price is a bit high, we suggest customers use it little by little.” Zhai said.

Meanwhile, a firm backed by e-commerce giant JD.com is selling necklaces with micro air filters priced at 699 yuan.

At the close of the annual meeting of parliament on Wednesday, Chinese Premier Li Keqiang, said air pollution must be brought under control and blue skies should never be a luxury.

Smog alerts are common in northern China, especially during bitterly cold winters when pollution masks are frequently out of stock.(NAN)
