IIT Bombay Scholar’s ₹2,000 Purifier Awaits December Launch

An affordable air purifier developed by IIT Bombay research scholar Rohan Kumar is scheduled for launch in December 2026, with its reported performance based on internal testing that has not been independently verified. The Enviroforge device combines natural fibres, adsorbent materials, beneficial bacteria and indoor plants to treat indoor air, Kumar said. Prices are reported to start at ₹2,000, with midrange models priced at ₹5,000 to ₹6,000 and a premium version at about ₹10,000. In an internal test, the purifier was placed in an enclosed room measuring 800 cubic feet. The test reportedly showed an 80% to 85% reduction in air pollution within 20 minutes.

The device uses layers intended to address different pollutants. Fibres including bamboo, coconut, banana and jute, alongside muslin, cotton, silk and micronanofibrillated cellulose, are intended to trap dust and particulate matter such as PM2.5 and PM10. Activated carbon, biochar and zeolite are among the adsorbents used to capture gaseous pollutants. Kumar says beneficial...
