It was only supposed to be a joke. It's not a joke any more.
A couple of enterprising Canadians, Troy Paquette and Moses Lam, have found there's a market in Beijing for clean, Canadian mountain air. This stuff:
"The way we capture the air now is a bit of a trade secret," Paquette, who goes down to Banff and Lake Louise from Edmonton, Alberta to fill giant cans with air through clean compression, and brings it home to bottle it, told VICE News.
"As much as it started out as a novelty idea, with the really bad smog they've had in Beijing, we're finding people are buying it as more than just a novelty, but for everyday use" he says. "There's been quite a demand."
The canisters have a cap mask attached to it and contain about 150 1-second sprays.
Single and twin packs of cans are being sold from $16 to $46. Aside from China, interest has also come from places like Iran and Afghanistan, said Paquette.
Paquette says it took a while for the product to gain any traction, but since the smog alert issued in Beijing last week, demand has skyrocketed.
Lam told the Telegraph their first shipment of 500 bottles was sold in four days, and a crate containing 4,000 more is on its way to China.
And Paquette said distributors in China have expressed interest in carrying Vitality Air in stores.
