Homemade Humidifier Cleaner?
I grew up using a swamp cooler, and we just changed the filters every season. We had mineral build up, but never saw any mold etc.
Homemade Humidifier Water Treatments?
Try putting the filter/wick in a large pot of water/white vinegar 2:1 or even 1:1 and boiling it for 20-30 minutes. That should dissolve the minerals in the wick and allow you to reuse it.
