MUMBAI, India, Nov. 2 -- Intellectual Property India has published a patent application (202611116345 A) filed by Chandigarh University on September 29, 2026, for Dual-Path Air Purification System.
Inventors include Aaditya Rajput; and Monica Pathania.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: The present invention relates to an AQI-adaptive dual-path air purification system comprising an air inlet, blower, self-cleaning rotary pre-filter, air-quality sensors, ESP32 controller and servo-controlled damper. The air-quality sensors continuously monitor the incoming air and the ESP32 controller selectively directs the airflow through a first or second airflow path according to the sensed pollution condition. Under relatively lower pollution conditions, the airflow is directed through a cyclonic pre-separator, whereas under relatively higher pollution conditions, the airflow is directed through a filtration path comprising a cyclonic pre-separator, electrostatic precipitator, HEPA filtration stage and activated carbon stage. The self-cleaning rotary pre-filter comprises a rotating cylindrical mesh and a stationary brush or suction nozzle for removing accumulated dust and directing the removed dust into a collection tray. The system thereby provides adaptive airflow routing, multi-stage air purification and automatic pre-filter cleaning.
