If you go to China these days, you want to make sure that you have the right kind of masks. N95 is the designation for pollution masks that are good at filtering. Mybeijinghealth.com has some good recommendations:

• 3M N95 8210 Plus. These filter out 95% of particulate 2.5 microns or larger. $18 for 20, they are not a bad buy on Amazon. the more important number is fit test because a leaky mask is pretty useless. These masks are also certified in the US.
• Vogmask. These are also highly rated but are washable, so for $30 not a bad buy if you are organized and don’t lose it. They are also a lot prettier than the 3M disposables.
