A humidifier keeps the atmosphere moist in a room. It helps prevent dryness that can cause irritation in many parts of the body, such as dry skin, nose, throat and lips. Most often, people use a humidifier to help with cold and flu symptoms by relieving sinus congestion.
A vaporizer generates a substance in the form of vapor, especially used for medicinal inhalation. A vaporizer works by heating water until it turns into hot steam.
A diffuser, especially when it comes to aromatherapy and essential oils, can come in a variety of ways. Common types are lamp rings, electric-powered, ceramic or reed diffusers. An electric-powered diffuser works much like a cool air humidifier, except it is specially made for using with essential oils (like our GO-2016 Tear Drop model). Diffusers disperse a micro-fine vapor that allows them to be suspended into the air for an extended period. It is much safer than burning oils in warmers and it retains the integrity of essential oils.
