Diffuser vs. Humidifier; What's the difference?

Last Updated: 12/17/2023

Understanding the differences between a diffuser vs humidifier

While diffusers have become more popular in recent years, there is still confusion about what a diffuser actually is, and when you would choose one instead of a humidifier. To truly understand the difference between the two, let's start with a simple definition.

A diffuser is a device that uses an ultrasonic vibrating disc used to break up essential oils in combination with water. This vibration creates fine particles that can be dispersed into the air, allowing us to receive different benefits from breathing them in. Part of the work of a diffuser is to disperse the particles throughout the space in a way that benefits the user and doesn’t overwhelm the room; many people say that their favorite reason to use their diffuser is to create a welcoming atmosphere through scent.

A humidifier is a unit, often with a large water tank, with its primary function being to add moisture to the air. Adding moisture is the easiest way to prevent dryness, which can cause irritation in many parts of the body. Dryness in the air is particularly common during the colder winter months or when using an air conditioner. Though personal size units are available, typically these are larger machines designed to provide humidity to a whole room or living space.

Essential oils to choose when selecting a diffuser vs humidifier 

A common misconception when it comes to diffusing essential oils is that it doesn’t matter what type of oils you use. While there are many reputable essential oil brands on the market, it’s exceptionally important when choosing essential oils to diffuse in your home that you know and trust the brand and the quality of oils being provided. Only 100% pure essential oils, free from any additives, adulterants and carrier oils, are optimal for use in your diffuser. At Saje, we feel confident knowing all our single notes and diffuser blends are 100% pure, potent and high quality essential oils that you and your family can trust to support your wellness. Some of our very favorite oils to diffuse in your home are included here:
