But the risk of putting tap water in a humidifier really doesn’t amount to a whole lot of excitement. And it’s up to you whether or not you want to deal with a little extra clean up.
Should you put a bottle of water in the humidifier if you don’t have any distilled?
Bottled water in a humidifier may be a little better than tap water because it does go through a little stricter of a purification process than tap.
But the minerals are not taken out of bottled water and since it’s the minerals that are the main issue with tap water, you’re only going to get a little bit of improvement using bottled water vs tap water.
How about using boiled water in the humidifier?
Boiling water will kill the bacteria or any type of fungal threat that could be present and water.
But the primary problem with boiling water then putting it into a humidifier is that boiling separates the sediment in the water and getting the water into the humidifier without getting the sediment in the humidifier along with it is going to be a little tough. Not impossible but tough.
Stream water seems like it would be a great solution for a humidifier but it probably has more minerals and sediment in it then tap water. And the likelihood of it already containing bacteria and fungus goes up a thousand percent.
