A novel air conditioning filtration technology developed at the Indian Institute of Technology (IIT) Bombay has been adopted by air purification startup AIRTH for use in its proprietary AC-integrated air purification solution, Filtrix. This technology effectively captures particulate matter in the PM2.5 to PM1 range, along with allergens and airborne pathogens.
AIRTH has implemented this filtration system across more than 30,000 air conditioners throughout India. According to the company, the integration is designed to enhance indoor air quality while improving the operational efficiency and longevity of air conditioning units.
Independent testing conducted at a Bureau of Energy Efficiency (BEE)-certified laboratory confirmed that the Filtrix system reduces power consumption by approximately 13% during continuous operation compared to baseline AC performance. After three months of usage, the system showed only a marginal 4% reduction in cooling capacity, affirming both compatibility and safety for long-term use.
The evaluation also found no adverse impact on the functioning of existing AC systems, underscoring the system’s suitability for widespread residential and commercial adoption. AIRTH stated that the Filtrix technology delivers significant benefits by improving air quality and simultaneously reducing strain on AC units. The purifier is engineered for seamless integration with standard air conditioners and offers purification efficiency up to five times higher than AC units with in-built purification systems currently available in the market.
Ravi Kaushik, CEO and Founder of AIRTH and an aerosol scientist from IIT Bombay, emphasized the broader health implications of the technology. He noted that one AIRTH AC purifier can reduce the health impact equivalent to inhaling 1,500 cigarettes, underscoring the public health potential of large-scale deployment.
AIRTH is an environmental technology company focused on improving indoor air quality through innovative, sustainable solutions. Founded with the mission to combat the adverse effects of air pollution, AIRTH utilizes advanced filtration and purification technologies, including antimicrobial coatings developed from research originally conducted at IIT Bombay. Their products are designed to convert everyday surfaces like curtains and cushions into air purifiers, making clean air more accessible in homes, offices, and public spaces. By combining science with practicality, AIRTH aims to create healthier living environments while raising awareness about the importance of breathing clean air.
