Product review (5 stars): Moisture!!!!!
It's dry out here in the Forty Mile Desert.  Pilgrims headed to California in the 1800s hurried past this area at night and shed their possessions to make the trip possible.  I have a  humidifier to make it more comfortable.  The water is full of hardness which makes filter replacements necessary often.  I get a constant supply through Amazon from various good providers.
