This mask was recommended for travel in India’s cities in an informative post by the (in)credible Kate Schutz, The Everyday Atelier! (http://www.everydayatelier.com)
I used to experience extreme headaches when riding to college on my bike. The polluted air in London has always had an effect on me which is why I decided to purchase this mask.
Honestly, do not just take Respro’s word for it. Head out and buy it. Good riddance to headaches and getting sick from all the polluted air in my city.
I have Reactive Airway Disorder RADs. I was confined to my home until I bought the City Mask. Thank you for a new lease on life.
