COPD, an inflammatory lung disease that causes obstructed airflow in the lungs, is even more widespread－close to 100 million of the country's adult population suffer from this chronic pulmonary disease, which has become the third leading cause of death in China.

慢性阻塞性肺病是一种导致肺部气流受阻的炎症性肺病，其传播范围更广——中国近1亿成年人口患有这种慢性肺病，已成为中国第三大死亡原因。

Referring to group founder James Dyson's knowledge of the science of airflow and how to rid air of pollutant particles, Dawson said, "In the past 25 years, we've been developing products relating to the airflow and filtration.

We're passionate about airflow and we want to apply what we have learnt in this field.

That's why we combine our airflow strengths with the filtration expertise, to make sure we can have whole room purification.

Stellantis also unveiled a new crossover concept, called the Chrysler Airflow, that is intended to represent the brand's future direction.

Due to defective airflow apparatus of condenser outlets, condensate water may drop into the combustor when the vehicles drive in high humidity and high-temperature environments, leading to engine failure and posing safety risks, the statement said.

The air balance package includes a high-end air purifier able to filter out PM2.5 that brings a softer, quieter airflow experience.
