I have a spare set of filters to make it easier to switch out when cleaning and such.
I feel that I'm careful to make sure they're dry when I store the spare set, and I rarely seal them up in an air tight container, but evidently I didn't dry them out completely and the container I store them in was sealed without my knowledge.
I pulled them out to swap filters today after doing a bit of a cleaning and found a few dark spots which I assume is mold.
Is there a way to clean this thoroughly or shall I discard the filters?
