If you only charge your humidifier with distilled water, try using a 50/50 mix of PG and distilled water next time.
If have used 50/50 already, you may want to try and put some uncharged climax beads in your unit. They should "suck up" the extra moisture.
Another option, hit your huidification device with a hair dryer, and don't charge full next time. Use just enough to distilled water to maintain 65-70 or use a smaller unit.
These are just thoughts, I have a hard enough time hitting 70% where I live
