With an idea that may seem crazy to some, it’s making one British entrepreneur thousands of dollars. 27 year-old, Leo De Watts is making some serious cash selling fresh air to customers living in polluted cities around the world.

De Watts launched his air farming company Aethaer, just last year and has sold hundreds of 20 oz glass jars, filled with air harvested from places like Dorset, Somerset, and Wales and shipped them off to cities like Beijing and Shanghai. However, fresh air doesn’t come cheap, one jar of British country air costs around $115 USD.

De Watts spoke about his company and how he harvests the air. He explained, “Quite often a lot of our orders are bespoke — we have clients who request very particular circumstances for their air,” adding, “Sometimes we’ll be at the top of a mountain, other times the bottom of a valley.”

De Watts, who hails from Dorset on the southern coast of England, currently lives in Hong Kong where he sells his fresh air at local street markets. He reveals the best air is from Britain during the colder months. He said, “The colder air means we can fit more in the container,” adding, “When it’s warmer, we can’t fit quite as much in.” De Watts also explains, once the jar is opened, the British air may only linger for a few seconds, but it’s understood many customers are purchasing the product more as a gift that will sit in homes unopened.
