Difference Between A Humidifier And A Diffuser


Diffusers are smaller devices made to be used with essential oils. Humidifiers, on the other hand, are bigger devices designed for regulating the level of moisture in the air. 

What are Humidifiers?

Humidifiers are devices made to keep a set moisture level in the room. Moisturizing air in the room is required in dry climates and in several climates when the heat is turned on in wintertime or fall. Dry air may cause problems with viral, bacterial, and dry skin problems, which make it much harder for some people to fall asleep. A lot of people use humidifiers for treating symptoms of sinus congestion, flu, and cold.

Humidifiers are quite different from diffusers since not all humidifiers support the mixing of essential oils for distributing them in the air. Since many humidifiers in today’s market have plastic components, it makes them incompatible with the essential oils. An essential oil may break down the device’s plastic components.

Your essential oil is dispersed with the nebulizing diffusers that make it easier for you to inhale it and the body to absorb it. Humidifiers won’t work in the same manner and would disperse oils only in the air, but won’t nebulizer it.

Other humidifiers are made to work both as a diffuser and a humidifier. More and more brands are manufacturing these kinds of units and it is actually a growing trend. However, if you are searching for a unit that will distribute essential oil the air, it’s a good idea to choose a personal diffuser that is ideal to use for essential oils.

What are Diffusers?

Diffusers come in different sizes, shapes, and types. These are used for diffusing different kinds of essential oils for aromatherapy purposes. Never confuse humidifiers with a diffuser. Diffusers are very different from humidifiers in a way they are designed to take essential oils, combine oils with water in the tank, and distribute to the air in the room.

There are various types of diffusers and these are evaporative diffusers, heat diffusers, nebulizing diffusers, and ultrasonic diffusers. They are made for vaporizing fine mist with the use of essential oils with cold effect.

Advantages of Diffusers

  • Diffusers frequently come with special lighting features including a color-changing LED light that works well to alleviate mental fatigue and elevate energy levels.
  • The diffuser’s cool mist may help you breathe better and lessen snoring with particular oils.
  • Diffusers may reduce the amount of fungus and bacteria in a room, which can trigger health problems.
  • The oil diffused in the diffusers results in a fine mist, which may be absorbed by your skin to have a stimulating or relaxing effect. It’s beneficial if you have dry skin.
  • The cool mist may have a purifying effect on the air around diffusers.
  • Diffusers work well to enhance the mood in the room by distributing essential oils.

Depending on your preferences or needs, you may have diffusers that operate in both ways as a humidifier and a diffuser or you may buy them as separate units.

Humidifiers vs Diffusers – Which is the Best?

Now that you already know about what humidifiers and diffusers are, it can still be a bit confusing with diffuser terminology. If you are new to essential oils, you might wonder whether diffusers and humidifiers can be the same or have primary differences.

Such devices can look similar. However, there are several legitimate differences that could affect your purchase.

Some of the major differences between humidifiers and diffusers are as follows:

  • Size of Tank – There are numerous kinds of humidifiers, but for you to help resolve your problems due to dry air, you will require a bigger tank compared to diffusers. To raise the level of humidity in your room, a humidifier requires a huge water tank, typically holding a gallon of water. Diffusers may hold about 300 to 500mL of water only if they hold water. You may pick an ultrasonic diffuser to spray the mist. However, it will not hold as much water as the humidifier.
  • Using Water – Various kinds of diffusers have different requirements to operate. Not every diffuser uses water, so if you want to gain maximum healing properties from essential oils, you would want a nebulizing diffuser. Such do not use water at all since they are meant to give you with utmost benefits from oils.

Once you opt to use a famous aromatherapy diffuser, you will have to use distilled water instead of tap water to get the best results. Ultrasonic technology makes ultrasonic vibrations through the water, which diffuses essential oils to the air. An ultrasonic diffuser system needs distilled water to make sure that there is no buildup of minerals, which happen often once tap water is used.

Which Should You Buy?

If your primary concern is maintaining an optimal level of humidity in your air, it is recommended to get a humidifier and a humidity reader since they’re designed for this.

However, if you want to distribute essential oil in the air, it is a good idea to get an essential oil diffuser. All in all, the choice is yours since it depends on what you really need.
