What is a humidifier?
A humidifier is a device that simply adds humidity, or moisture to the air. People use humidifiers if the air is particularly dry inside. Adding water vapor into the air can help with respiratory issues, dry skin, allergies, or even headaches. They are very popular however humidifiers are not equip to properly diffuse oils.
Putting essential oils In your humidifier
A lot of people wonder if you can put essential oils in a cool or warm mist humidifier. The answer is, NO! Standard humidifiers are not made to diffuse essential oils. Essential oils are corrosive and can damage or break down the plastic inside your humidifier. The only exception is if you purchased a two-in-one humidifier/diffuser.
Both ultrasonic diffusers and humidifiers release water into the air but both are not meant to break down essential oils. So it is accurate to say that all ultrasonic essential oil diffusers ARE humidifiers but not all humidifiers are oil diffusers.
So how can you benefit from BOTH added moisture to the air and the relaxing aromas of essential oils? That’s simple. Just purchase a cool mist humidifier & essential oil diffuser in one!
