Avoiding air pollution - do you think it's reasonable to just wear N99 masks everywhere now?

Recommended Posts

Like, thomas talhem has an amazing blog (and quora answers) on this - there is really no minimum safe dose of pollution, and you can see pollution spikes in even small amounts next to the road (as cars braking causes road dust to go into the air). The plume air quality sensor is great but it still doesn't capture ultrafines, which seem abundant near airports. Coronavirus kind of makes me glad that wearing masks everywhere will probably be forever-destigmatized/un-weird.

and american cities generally have air pollution levels below the WHO-I limits, but even then, they often have localized spikes.

It depends whether your lungs are all right with that. AFAIK, the only disadvantage of higher protection masks is that you must exhert more effort to breathe, since there is a greater pressure drop (more suction required) caused by the filtering material. Probably, not ideal for running. Risk of emphysema? I don't know, but surely not advised to those who already have some breathing problems.

Yeah, I don't like wearing them continually that much b/c of the increased resistance, but air pollution is so horrible for you it's worth the risk.

Exerting more effort to breathe might in fact be good for your lungs..
