BMW BreatheFree cleans the atmospheric environment around the vehicle. It uses a Regenerative Carbon Dioxide Removal System, similar to that of the International Space Station, to capture CO2. It also uses carbon filtration and BASF PremAir catalysts to convert ozone to O2. Ducting allows cleaning of outdoor air and interior air. Thus, the presence of a BMW not only enhances urban aesthetics and property value. It literally makes your city a better place to live.
The system detects high levels of Carbon Dioxide and Ozone through onboard sensors. Its technology then removes these gases powered by the power grid when plugged in (i3 and i8). The system is regenerated/recharged as part of your oil change provided by BMW Service.
