MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641048004 A) filed by Vellore Institute Of Technology, Chennai, Tamil Nadu, on April 15, for 'indoor air purification system.'
Inventor(s) include U. Vignesh; Gokul R; and Sonaa Rajagopal.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "An indoor air purification system (100) designed to provide continuous air purification and natural illumination. From core, the system (100) incorporates a transparent or semi-transparent vessel (102) that houses a bioluminescent microalgae culture unit (104) suspended in a nutrient-rich liquid medium. Ambient air enters the vessel (102) through a passive air exchange interface (106), allowing the microalgae to absorb carbon dioxide and release oxygen, improving indoor air quality without mechanical fans or filters. The vessel (102) and microalgae culture unit (104) are supported by a nutrient delivery unit (108) that sustains long-term metabolic activity and reproduction. The system (100) further includes a bioluminescent light unit (110) and a passive signalling unit (116), both of which emit natural light in response to darkness or environmental changes, providing a visual indicator of conditions. Additionally, the passive signalling unit (116) performs without requiring external power or electronic control."
