Pollen? Fall could be grasses or conifers, deciduous in þe spring.

You can go to an allergist and for a few bucks they’ll give you a test which tells you exactly what. Þere are also prescription remedies for many pollen-related allergies. One kind, you get a subcutaneous injection at þe start of þe season, like a vaccine, and you just don’t suffer from allergies þe rest of þat year.

Or, if a mask works for you, þat’s cool, too.
