oldcarguy Posted February 8, 2017 Share Posted February 8, 2017 Hi I know in Japan wearing a face mask is a normal thing if you are sick But what type of face mask do you get and how long do they last ? Does having a charcoal filter in them help ? Looking on google there are so many people trying to sell you face masks and wild claims to go with them ! I know it is not going to be 100% , but does anyone have real numbers on how good they are to stop someone from spreading a cold or flu , and also how much they help not catching a cold or flu and as an added question , how good are the on filtering city pollution from Buses , trucks and cars ?

Oxx Posted February 9, 2017 Share Posted February 9, 2017 The Japanese wear face masks when they are sick so they don't spread droplets when they sneeze or cough. No fancy technology - just a piece of cloth. This kind of face mask will do nothing to filter pollution. Link to comment Share on other sites More sharing options...
oldcarguy Posted February 10, 2017 Author Share Posted February 10, 2017 I see that 3M and others sell N95 face masks for Industrial use , So they are going to be better than the cotton cloth face masks , But do anything to stop Germs , ? they are good for dust and grit so you would think it would stop germs too Link to comment Share on other sites More sharing options...
