How do you control humidity?

This unit does it all.

Runs about 15 watts on the power cycle I use. Highly recommended!!

I do have to top off more though because it drys out the air in the room.

That sounds pretty sweet!

In my basement I have well over 1000 gal. of water. I run an exhaust fan during the day (14 hrs) and dehumidifier at night (10 hrs.) in the winter and the fan on all the time/no dehumidifier in the summer. This keeps my humidity in the 40-50% range, which isn't too bad where I live.
