Title: 1.5 gal. capacity? Not even close!
Review: From the line where the machine cuts off due to low water level to the "full" line there is room for exactly one quart of water! One and one half gallons is, of course 6 quarts. This thing worked for me about 4 hours before the water level dropped too low and it automatically shut off. The purpose of buying this humidifier is to be able to sleep. Getting up 2-3 times per night to add water does not work for me.
