Too hot but it does work
We live in South Korea which has a lot of pollutuon.  I have asthma and allergies and if I wear a vog mask, it does seem to help.  But I find riding a bike or even walink on a warm day too hot in this mask.  I sweat and feel lile I cannot get enough air.  I desperately need another alternative to this mask.  😔
