Can I Use Tap Water in My Humidifier?
You cannot put tap water in a humidifier even if the water is safe to drink. This is because tap water contains mineral deposits that promote the growth of mold and bacteria. When the tap water is broken down and dispersed as mist, the mineral residues will be spread as white dust and end up on your bed, furniture, wall, and floor. Inhaling to white dust can trigger many allergies like sneezing, red eyes, itchy skin, and breathing difficulty. In long-run it will aggravate many respiratory conditions including asthma. Unless the tap water is filtered or demineralized, never risk putting in a humidifier.

Do You Have To Use Distilled Water In a Humidifier? What About Boiled Water?
To upkeep humidifier’s durability and excellent safety record, use only distilled/ demineralized water. It is the best water to use in a humidifier as there is less mineral accumulation that would cause safety and health hazard. However, most people would opt for boiled water instead of distilled water thinking it is the same thing. It is not. Distilled water is boiled until it turns to steam and cooled off to become water again. This effectively removes all mineral residues and any microorganisms. Boiling water to 212 °F will kill the microbes but it will not remove minerals and other chemical contaminants. So never use boiled water in a humidifier.
There are a lot of benefits to a humidifier. It is compact, cheap, and very easy to use. By adding moisture into the air, it makes breathing more comfortable, reduces infections, and protect wooden items from dry rot. Still, a good humidifier will require constant care and maintenance. The reservoir will need to be clean every 3-7 days depending on usage frequency. The water will also need to be changed every couple of days to prevent stagnation. If there is filter involved, make sure it is clean periodically.
