MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202611000784 A) filed by Chandigarh University, Mohali, Punjab, on Jan. 5, for 'voice-controlled smart air purifier with iot-based temperature monitoring and hepa filtration system.'
Inventor(s) include Rohit; Hemanta Yogi; Prince Penny Hembrom; Dr. Harpreet Singh Lubana; and Mr. Kiranpreet Singh Kang.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "The present invention represents a Voice-Controlled Smart Air Purifier integrating IoT-based monitoring and a high-efficiency HEPA filtration system. Powered by an ESP32 microcontroller, the system uses six air-quality sensors, MQ-2, MQ-9, and MQ-135 at both inlet and outlet, to compare polluted and purified air in real time. A DHT11 sensor continuously measures temperature and humidity, while a centrifugal fan forces airflow through an ISO 29463-certified HEPA filter, capable of removing 99.97% of fine particles. The purifier body, made from IS 303:1989 plywood, includes optimized inlet and outlet vents for effective circulation. Sensor data is displayed on an LCD and transmitted to the Blynk IoT platform for remote access. Additionally, voice commands enabled via MIT App Inventor provide convenient, hands-free device control, offering an efficient and eco-friendly indoor air-quality solution."
