Delhi Teen Builds Affordable Air Purifier
A 14-year-old boy named Krrish Chawla from Delhi made a special machine called Breathify that cleans the air.
It costs only Rs 4,990, which is much cheaper than other air purifiers.
He started working on this because he used to get sick a lot during Delhi's smoggy winters.
He made over 320 different versions before he got it just right.
The machine uses a special way to pull in dirty air, clean it, and then push out clean air.
It can make the air inside your home very clean, even when the air outside is very polluted.
The machine is also good for the environment because it's made from things that can be recycled and doesn't have much plastic.
For every machine sold, Krrish will plant a tree to help the environment even more.
Krrish Chawla, a 14-year-old from Delhi, developed an affordable air purifier called Breathify.
Breathify costs Rs 4,990, significantly cheaper than other air purifiers on the market.
The purifier uses a patent-pending 'Reverse Air Technology' to efficiently clean air and reduce energy consumption.
Independent testing shows Breathify can reduce indoor AQI to 4 from levels exceeding 400.
The device is made from recyclable materials and is 99% plastic-free, with a commitment to plant a sapling for every unit sold.
