Angad Daryani, a Mumbai-born prodigy who built a robot at age 8 and joined MIT at 14, now leads Praan Inc., a cleantech startup designing the world’s most advanced filterless air purifiers. His innovation aims to combat India’s air pollution crisis with scalable, affordable, and sustainable technology for urban environments.

Breathing Innovation: How Angad Daryani Is Reimagining Air Purification with Praan

In a country grappling with hazardous air quality, Angad Daryani, a 25-year-old inventor from Mumbai, is offering a breath of fresh air—literally. His startup, Praan Inc., has developed a filterless air purification system that’s being hailed as one of the most advanced in the world. The technology is designed to tackle urban pollution without the high maintenance and energy costs of traditional purifiers.

Key Highlights of Angad Daryani’s Journey and Innovation:

Early Genius

Built his first robot at age 8 and a 3D printer by 13.

Dropped out of traditional schooling at 14 and began working with MIT professors, initiating two years of collaborative tech development.

Academic and Technical Foundation

Studied electrical engineering at Georgia Tech, where he focused on scalable climate-tech solutions.

His personal experience with asthma and Mumbai’s toxic winters inspired his mission.

Praan’s Breakthrough Technology

The company’s flagship product, Hive, uses electrostatic precipitation and airflow engineering to remove pollutants without filters.

It’s designed for homes, schools, and public spaces, offering low-cost, high-efficiency purification.

Filterless Advantage

Unlike conventional purifiers, Hive doesn’t require frequent filter replacements, reducing waste and operational costs.

It’s built to withstand India’s harsh pollution levels, including PM2.5 and nitrogen oxides.

Social Impact and Accessibility

Praan aims to make clean air accessible to underserved communities, not just premium buyers.

The startup is also working with schools and NGOs to deploy units in high-risk zones.

Global Recognition

Praan has received attention from climate-tech investors and innovation platforms, positioning India as a hub for deep-tech environmental solutions.

Angad’s story is a testament to how early curiosity, bold outreach, and purpose-driven innovation can converge to solve some of the world’s most pressing challenges.
