I wear my mask when out on my ebike to protect myself from exhaust fumes and chemical sprays on residential lawns. In the warmer months I need to wear it when travelling outside of town in a car to protect myself from agricultural pesticides drift as I live in an area that grows mostly corn and beans, probably mostly GMO and sprayed liberally with pesticides. I also wear it in grocery stores, thrift stores and the mall. Even with the mask I rarely venture into a mall.

Be fragrance-free. It’s good for you, it’s good for me.

Seriously "Sensitive" to Pollution 
Brenda shared this about her mask:
“It’s a Respro City. I have tried I Can Breathe, Respro, and a Vogmask. Not terribly happy with any.”
I used to love browsing thrift stores; no more! I find all the items that come from them need to be hung outside for 6 months or more. (My wife still shops.I rarely do.) I suspect they add a fragranced mold/mildew/lice/bedbug inhibiting agent to received items. Though I’ll allow that maybe it’s just old perfumes.
