Yes it is compatible with 3M 7502 Respirator

What is the average lifespan of the filters before you need to replace?

As I’ve seen here on the pakage written mostly in Chinese which I don’t understand and also few in English, which says that it must be use before the expiry date. I searched for the manufactured and expiry dates but most were written in Chinese, and I found one numerical print which says, 08.2021 so, I guess that’s the expiry date. Regarding the lifespan while exposure, I guess it will depend on the how much it is exposed to different kinds of pollution, it will last longer in a lightly polluted air and shorter in a heavy air pollution. I don’t find any details written in English so, I think the replacement will be whenever we want a fresh filter.
