- 01Captures PM2.5 at the molecular level under typical indoor humidity ranges.
- 02Designed for retrofit into existing HVAC and vehicular systems.
- 03Patent filed in Thailand with a parallel international application underway.
A new aerosol-based purification technology developed by CMU's Climate Crisis cluster has been formally registered with Thailand's Department of Intellectual Property. The formulation binds particulate matter at the molecular level and is engineered to remain stable under the humidity and temperature ranges typical of Northern Thai homes.
Unlike conventional photocatalytic coatings, the aerosol can be reapplied to existing surfaces without specialized equipment. Field tests in classrooms and clinics in Chiang Mai showed measurable reductions in airborne PM2.5 within minutes of application.
The team is now exploring two parallel deployments: a consumer-grade canister for residential use and an HVAC-integrated variant for fleet vehicles. A parallel international patent application is in preparation.
