Though there is seeming usefulness of a humidifier but it doesn’t in any way replace the importance of a diffuser.

They are also easy to use, portable and come with useful features.

Types of Essential Oil Diffuser

Types of Essential Oil Diffuser

Evaporative diffuser: this unit uses a fan to blow out the essential oils scents through a filter or pad. One downside of this unit is that the oil aroma is not concentrated or ‘thick’ because they seem to have been ‘watered’ down.

Ultrasonic diffuser: this unit combines water and oil to disperse the aroma of the essential oil into the atmosphere as fine mist. They are effective but not so much as the nebulizer diffuser. The ultrasonic diffuser can perform dual function- it can serve as a humidifier when the essential oil is excluded; and as a diffuser with the inclusion of essential oil.

Heat diffuser: this unit uses heat energy to disperse the essential oil scents into the air. Some uses high level of heat for this purpose and therefore do not produce a highly concentrated aroma, but the ones that use a low level of heat are more effective.

Nebulizing diffuser: this is a powerful diffuser that doesn’t use fan, heat or water to disperse essential oil into the atmosphere. As such, the scents are powerful and undiluted for a better experience. It uses an atomizer (similar to the top of a perfume) to disperse 100% undiluted essential oil.
