Frederik Hendriksen is the co-founder of Rensair, pioneering the world’s first air quality ecosystem to cut carbon, costs, and pollutants through next-generation ventilation technology. Rensair’s connected solutions optimize existing HVAC systems, reducing energy costs while delivering cleaner, healthier indoor air—without expensive infrastructure upgrades. Their tech traces back to Frederik’s father, a ventilation engineer, who originally developed a standalone air purification system for hospital operating rooms, and to help Frederik’s twin brother manage severe asthma. Inspired by this innovation, Frederik and his team are now hacking HVAC to tackle the climate crisis and transform building ventilation, ushering in a new era of carbon efficiency, cost savings, and clean indoor air.
