Heavenly purification


Fresh air, also when cycling, keeps us healthy.

Now, an engineering student from India has founded a startup so that his compatriots can benefit too.

The 23-year-old has invented a machine which absorbs the harmful elements of smog, such as black carbon, and captures them in a large container.

The human-sized devices cost less than a new mobile phone and are easily installed. A single device filters 8.5 sqm of air per minute and needs emptying every two to six months.

With the addition of a binding agent such as clay or cement, the captured pollutants can be used to manufacture floor tiles.

The machines are being tested as part of a pilot project soon.

The sky’s the limit.
