The Delhi administration, in the news for trying everything in the book to control its air pollution, may take a look a look at China – which is importing air to overcome its smog problem.
A Canadian company selling air bottled in a ski resort says it's now seeing huge demand from Chinese customers.
Vitality Air said that the first batch of 500 canisters filled with fresh air from the Rocky Mountain town of Banff went on sale in China last month and sold out within two weeks.
"Now we're taking lots of pre orders for our upcoming shipment. We're getting close to the 1,000 mark," said Harrison Wang, director of China operations.
The air sells for $14 to $20, depending on the size of the canister.
Northern China is often cloaked in smog, especially during the cold winter months when homes and power plants burn coal to keep warm. Last week, Beijing issued its first ever red alert because of poor air quality, closing schools and restricting traffic.
Vitality Air co-founder Moses Lam says he came up with the business idea last year after listing a bag of ziplocked air on eBay, which sold for 99 cents.
"We wanted to do something fun and disruptive so we decided to see if we could sell air."
Lam, who is based in the city of Edmonton, says he makes the four-hour journey to Banff once every couple of weeks and spends 10 hours bottling the air.
"It's time consuming because every one of these bottles is hand bottled. We're dealing with fresh air, we want it to be fresh and we don't want to run it through machines which are oiled and greased," said Lam.
Sales in Canada are mainly for novelty value, says Lam, but in China people believe it has a real functional purpose.
"In North America, we take our fresh air for granted but in China the situation is very different."
Wallace Leung, a professor at Hong Kong Polytechnic University, told CNN that buying bottles of air was not a practical solution to China's air pollution.
"We need to filter out the particles, the invisible killers, from the air," said Leung, who conducts research on the effectiveness of face masks. "One bottle of air wouldn't help. I would be very cautious."
But Lam says his company's products are more than a gimmick.
"If China can import food, water, why shouldn't they have the right to import air?"
