In
late March 2014, our EB-5 business delegation was traveling in 5 cities
around China. Air pollution was the major concerns we had. To stay
healthy and minimize risks, we were fully prepared with N95 Particulate Respirator masks made by 3M. Some of us also prepared with Halo Oral Spray (against airborne germs) and Nozin Nasal Sanitizer
which can be purchased at Amazon.com. These items are extremely
helpful. They are highly recommended for you to use during the travels
in China. Air pollution is a serious problem in many Chinese cities,
Beijing is the worst so far during our visit in late March. There are a
couple helpful websites that you can check on prior to traveling to
China, such as the Chinese Cities Real-time Air Quality Index (AQI) at http://aqicn.org/city and US Embassy in Beijing. The
air monitor's measurements are expressed in the form of PM 2.5 concentration
(micrograms per cubic meter, µg/m3) and corresponding AQI.
The following chart was from the US Embassy in Beijing official website.
You can find more information about air quality in Beijing at the
Embassy website http://beijing.usembassy-china.org.cn/aqirecent3.html
