Don't want to trade filtered air for mold!

If you are using synthetic sponges for the filters, add a tablespoon of bleach to a pint of water - no mold.

Or, isopropyl alcohol - anything over about 6% will inhibit mold as well. You may use alcohol on natural (cellulose) fiber sponges.

Borax is a good anti-fungal too.
