介绍:
More than 70 companies are being represented at an Ecotech Exhibition taking place in Shanghai.
Both domestic and foreign companies are displaying the latest technology connected to environmental issues.
Products connected to personal air purification are one of the highlights, given China's notorious air-quality problems.
Companies represented at the event are looking to cash-in on the growing market for air purifiers.
Some 7 billion yuan worth of air purifiers were sold in China last year, up 80-percent from a year earlier.
It's expected sales in China may hit 9 billion yuan this year.
