If you are commuting, whether that be in your own mechanically powered private conveyance, or by public conveyance such as rail, bus, metro, underground rail. Events and emergencies could happen in transit that could be a threat to yourself and to others. If your breathing is compromised YOU are compromised. I show just one product part of a product line which is being sold by a company here in England called Emergency Protection Limited https://www.emergencyprotection.co.uk/ they very kindly sent me a demonstration version of the 'Maskito' a very compact escape mask that is very small and portable but could offer you a lot of protection to your breathing should something happen on your journey.
Be safe, be prepared and travel safely.
