MUMBAI, India, July 24 -- Intellectual Property India has published a patent application (202641068447 A) filed by Saveetha Institute Of Medical And on June 01, 2026, for Thermally Stable Cabin Air Filter Frame For Automotive Hvac Systems.
Inventors include R. Endymion Grosious; Dr, L. Natrayan; and Dr Ramya Mohan.
The application for the patent was published on July 17, 2026, under issue no. 29/2026.
Abstract: The present invention relates to a cabin air filter frame manufactured using a polycarbonategraphene composite material. Traditional filter frames made from polypropylene or ABS often deform under thermal cycling, absorb moisture, and lose structural rigidity over extended use, reducing filtration efficiency and compromising air-flow stability. The proposed invention utilizes a graphene- reinforced polycarbonate matrix that provides superior moisture resistance, enhanced stiffness, and improved thermal stability. The graphene component additionally offers natural antibacterial properties, inhibiting microbial growth on the filter frame surface. The composite structure maintains its shape in varying environmental conditions, ensuring consistent sealing, proper filter alignment, and long-term durability inside the HVAC system. By integrating highperformance composite materials with optimized frame geometry, the invention delivers a robust, dimensionally stable, and hygienic filter frame suitable for modem automotive cabin air filtration assemblies.
