It is better to have a tank that holds a sufficient amount of water. Yes, it’s a must to refill a humidifier but you could minimize the number of times you have to do this.

Tanks with a minimum capacity 1 gallon aren’t bad. Anything below this means a lot of hard work. Obviously tank capacity also goes hand in hand with the size of the room.
