David asks…
Does a humidifier have benefits for a singer?
I have heard that a humidifier has great benefits for a singer. And so I would like to get another person opinion on the subject.
answers:
Yup! Moisture in the environment makes your vocal chords more flexible and also makes sound waves travel farther. Hence why people prefer to sing in the shower

Sharon asks…
How do I stop the white dust from coming out of the humidifier?
I haven a cool mist ultrasonic humidifier. This product is great for increasing the humidity in my home, but the minerals in my water cause a white dust to collect on surfaces throughout the house. I’ve heard that there are additives to put in the water to decrease this dust. Does anyone know about this? Does anyone know about other solutions?
answers:
Distilled water should do this trick but you can also try using the demineralization cartridge or water additive. You may also want to thoroughly clean your ultrasonic humidifier. If the humidifier has been with you for more than three seasons then perhaps it is time to replace it.

Paul asks…
What is the difference between a vaporizer/diffuser/humidifier?
I’m a bit confused about the difference between a humidifier, vaporizer and diffuser. Any help would be great.
answers:
A humidifier adds moisture to the air; great for winter time in cold areas.
Vaporizers add to the moisture like a Vicks vaporizer add vicks to the mist let out. And, diffusers add a scent to the air by allowing a scented oil to evaporate through special wooden dowles.
