Interiors specialist Antolin, HVAC supplier Sanz Clima and photocatalysis specialist CleanAir Spaces have developed the first prototype vehicle interior air purification system based on ozone-free photocatalysis technology.

CleanAir Spaces has been involved in its development as a supplier of catalytic substrate technology, Sanz Clima as an adapter of technology to the environment, and Antolin as a developer and integrator of the product inside the vehicle.

In order to adapt it to customer needs and as a first step to potential commercialisation, the project is being presented to vehicle manufacturers.

Advanced photocatalysis technology is based on hydrogen peroxide (H2O2) that is generated from the humidity of the air when a light of specific characteristics falls on the specifically designed substrate. Hydrogen peroxide (H2O2) envelops pathogens, viruses, and bacteria in the air and on surfaces, neutralising their infectious capacity. Thanks to its oxidising power, it is also able to effectively remove volatile organic compounds and odors.

Testing has confirmed the technology is effective and does not generate harmful compounds for people or animals. The maximum concentration of hydrogen peroxide (H2O2), the active compound generated by the technology, is less than 0.1 ppm, that is, 90% below the limit established by national and international regulatory agencies, making its use compatible with the presence of passengers in the vehicle cabin.
