We use a Honeywell humidifier with the wick/filter, fan, and two tanks you have to constantly fill. It goes through over 2 gallons a day, and it makes a difference, but you really have to keep up on filling the water. We have a freestanding stove in the middle of our living space, so it gets pretty dry. If you slack off on filling the humidifier for a day, you get lots of sparks and static pops when you pull the covers back to get in bed. It makes a difference in comfort if you have a cough or sore throat too, and cuts down on the nose bleeds from the dry air.
