Climate Impact and Cleaner Air in a Single Scalable Solution
Our Solution
Our solution is a photochemical filtration technology that can be integrated into existing HVAC systems to oxidize ambient methane in passing airflows, while improving indoor air quality by inactivating airborne pathogens such as viruses and bacteria. Watch our video below which explains more about Clear Methane.
Advanced Methane Mitigation
We are providing an advanced methane mitigation technology that oxidizes ambient methane (CH4), something no existing product does at scale or low concentrations.
Reducing Co-pollutants
The technology not only removes methane but also has the potential to reduce co-pollutants such as Volatile Organic Compounds (VOCs) and Particulate Matter (PM), bacteria and viruses delivering immediate air-quality benefits alongside climate impact.
Safe & Low-cost
By using safe, low-cost materials to enhance methane oxidation and aligning with the standard filter replacement cycle of every three to six months, the solution offers a practical, affordable, and easily adoptable pathway for large-scale deployment.
Our solution is a photochemical filtration technology that can be integrated into existing HVAC systems to oxidize ambient methane in passing airflows, while improving indoor air quality by inactivating airborne pathogens such as viruses and bacteria.
By integrating low-cost photocatalytic coatings with UV-C activation (already part of ventilation systems) into standard HVAC filters, we create a simple retrofit capable of oxidizing methane at ambient concentrations and removing co-pollutants such as VOCs as well as Particulate Matter which are harmful for human’s health.
The system requires minimal additional energy, fits within standard filter replacement cycles, and leverages existing ventilation infrastructure for fast, low- disruption deployment. Our commercial strategy is to license this technology to filter manufacturers, enabling rapid, global scale-up through established supply chains.
