Ersa removes CO2 and humidity build-up caused by the breathing of the car passengers to allow for full recirculation of interior air while maintaining its quality. In so doing, Ersa drastically decreases the load on HVAC systems and allows for range increases of 20% compared to an already optimized air-conditioning mode.

Ersa, creates an indoor air bubble, facilitating healthier cabin air and longer external air filter lifetimes by reducing outdoor air pollution introduced into the car cabin by up to 80%. Multi-pass HVAC filtration is enabled, resulting in x10 higher air filtration efficiency and removing dangerous gases such as NOx & SOx. The enhanced air recirculation significantly reduces the car’s Heat, Ventilation and Air Conditioning power demands and increases electric vehicle range by up to 20% in cold weather.
