MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641051482 A) filed by Dr. Krishnapriya M G; Dr. Alosh James; Anna Pauly; Lazar Saju Francis; Nivedith K Nirmal; Thajus Daison; and Fleming Joby Kuttikkat, Irinjalakuda, Kerala, on April 22, for 'a real-time air quality index monitoring and purification system using organic filter.'
Inventor(s) include Dr. Krishnapriya M G; Dr. Alosh James; Anna Pauly; Lazar Saju Francis; Nivedith K Nirmal; Thajus Daison; and Fleming Joby Kuttikkat.
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: "The present invention relates to a real-time air quality index (AQI) monitoring and purification system designed to assess and improve indoor air quality using a sustainable approach. The system integrates a multi-parameter air quality sensor module with a microcontroller unit to continuously monitor pollutants including particulate matter, carbon dioxide, and volatile organic compounds along with temperature and humidity. The system provides real-time AQI values through a display interface and enables wireless transmission for remote monitoring. A threshold-based control mechanism automatically activates a fan-driven purification unit when pollutant levels exceed predefined limits and deactivates it once air quality improves. The purification unit comprises a multi-layer organic filter including natural fibers for particulate removal and activated carbon with amine functionalization for gas adsorption. The system is compact, energy-efficient, eco-friendly, and suitable for indoor applications such as homes, offices, and classrooms."
