@normajean13 I get N95 masks with an exhalation valve, usually HDX brand at Home Depot or 3M online. My husband is wearing one now as he bows because it is dry and dusty here. A number of our neighbors wear them as well- the valve makes them accumulate less moisture.
Yikes! A cold front blew in as I am sitting outside typing - I need to hurry and put stuff away before it (finally) rains.
