GM China Engineering is developing an advanced filtration system for global use that utilizes a combination of proven technologies. It adds three layers of protection for consumers, to filter most airborne particles; to help clean the air inside the vehicle via an air ionizer; and to provide drivers real-time information regarding PM2.5 levels inside and outside the vehicle.
The new system aims to reduce harmful particles entering the cabin by up to 80% within five minutes and to make in-vehicle air up to 10 times cleaner than outside air within 10 minutes of operation.
The system using the new HEPA (High-Efficiency Particulate Arrestance) filter and ionizer builds on climate control systems already available in the all-new Chevrolet Cavalier and Cadillac CT6, both of which GM builds in China.
The Cavalier’s climate control system comes standard with a PM2.5 fine particulate matter air filter that traps and filters out more than 99% of pollutants ranging in size from 0.3 μm to 10.0 μm.
The CT6’s Quadzone climate system offers ionizing air purification that radically reduces airborne dust, pollution, bacteria and pollen from the cabin. It also eliminates odors such as tobacco smoke. In addition, the Quadzone system allows passengers to personalize the temperature and airflow for each seating position. When the system is activated, an ionizer status indicator lights up on the CT6’s climate control touch screen.
The health and safety of our customers is top of mind. The new air filtration system will address their need for clean air by keeping pollution levels in the cabin significantly lower than outdoor road levels, and will do it more quickly.—GM China HVAC Engineering Manager Kevin Wang
