Warm or cool humidifier?
At first, both accomplish the same goal. However, it is important to consider that warm humidifier is supposed to be cleaner, as the warm air can kill the germs more effectively. If you have children, perhaps it might be more secure for them.

The run capacity
Usually, the run capacity depends highly on the size of the tank. Bigger tanks also mean bigger humidifiers. You must combine information about both things to make your final decision.
Determining in advance where you want to place the humidifier is essential to make your decision.
