It takes about 1.6 gallons of water, on low it lasts about two days, on high it lasts about 1 day when full. you can set the timer, or base it on humidity in the room. The humidity that the unit reads and what my thermostat reads are off as much as 10%, which makes sense, so you have to account for that when setting it.
The humidifier works in relieving the dryness due to forced air furnace during the night. Very quiet operation, easy to use and set up. The variable adjustments allow for low to high amount of moisture release. Bought for the master bedroom and bath--unit sits between the sinks. Helps the air in the next bedroom, also. The reservoir usually lasts one night but on low can last two nights. Would suggest an automatic timer for the unit if people forget to turn it off. We have well water and use a faucet filter to fill the unit.
This unit is so easy to use. Easy to follow instructions. Item is quiet and it sprays the perfect amount of mist into the room which helps to stop my nasal problems. The features are excellent, the auto shut off, the timer set, the night light, just to name a few. Priced excellent and couldn't ask for better A++++
