The Indian man who made the world's most affordable water filter

In India, millions still don't have access to safe drinking water. For many families, that means depending on expensive bottled water or relying on unsafe sources.

That's the problem Niranjan from Belagavi set out to solve.

He began with a simple idea which is to build small, affordable filters that could fit onto any bottle, making clean water accessible for travelers, students, and even the Indian Army and CRPF. But he didn't stop there.

Most RO purifiers waste three litres of water for every one litre they clean. Niranjan wanted to change that. His new RO system is designed to save up to seventy percent of that wasted water, with a smart storage container so the reject water can be reused for washing and cleaning. It's a solution not just for homes, but for offices and even large-scale commercial use.
