Air permeable mason jar lids for dried herbs?

Is there a type of lid that will help preserve dried herbs in mason jars? I am looking to preserve dried lemon balm, spearmint, sage, etc. in a wooden cold locker that is exposed to ambient air moisture. I thought something that would allow air movement but block moisture would be good, but I don't know. The locker sits in my "basement" which is dirt (no finished concrete).

I live in Susanville, California and we have dry warm summers with cold average(?) winters. Most of our yearly rain comes from late December to April.

once herbs are dry, i think sealing them completely (no air exchange) up is best.

For fermenting, I take a basket style coffee filter and screw it on with the screw lid to keep bugs out and allow air through. Would that work?

I typically use silica packets in my herbs but am not always thrilled with how well they keep. Perhaps I should do a better job of drying somehow?

that's kind of a tall order. of the molecules that make up the air around us, water is among the smaller. nitrogen, oxygen, and carbon dioxide are all quite a bit larger. water does have some chemical properties that make it behave differently from those others and might allow a barrier that prevents the movement of water while allowing the others. I don't know of any that are readily available, and I'm not sure what good that would do you if you did find something. allowing oxygen in, for example, would degrade your herbs. and any water impermeable barrier will keep any moisture in just as well as it keeps moisture out.

To me this sounds like an invitation to invite mold a chance to grow.

Dried herbs work best in an air-tight jar.
