Arunachalam Purunian

Indian social entrepreneur who invented low-cost sanitary pads to combat menstrual poverty

Arunachalam Purunian (born 1963) is a Tamil Nadu-based inventor known for creating an affordable sanitary pad-making machine. Born into poverty, he observed the struggles of women in his community who couldn’t afford menstrual hygiene products. In 1998, he developed a manually operated machine that produces low-cost pads using locally sourced materials like banana fibers and coconut husks. His invention, costing just $75 per unit, has empowered over 10,000 women across India to start microbusinesses. Purunian’s work directly addresses menstrual taboos and economic barriers, improving health outcomes for millions. His story inspired the 2019 Bollywood film Pad Man, though he remains relatively unknown internationally.

Purunian’s efforts align with UN Sustainable Development Goal 5 (gender equality) and 3 (good health). His machines are distributed through NGOs like Ashoka, and his methods have been replicated in Bangladesh and Nepal. Critics argue his pads lack medical certification, but he insists affordability trumps perfection for marginalized communities. His advocacy for menstrual equity has influenced India’s 2018 Menstrual Hygiene Management policy, mandating free pads in schools. Purunian’s legacy challenges the global stigma around menstruation while proving grassroots innovation can drive systemic change.
