All About Essential Oil Diffusers

Essential oils have become popular in spas providing aromatherapy to their clients, but how to properly infuse the air in your spa is another story. For this, Essential oil diffusers play an important role. Essential oil diffusers break down the essential oil particles so that they are small enough to be inhaled and the occupants of the room can reap the benefits. However, there are several different types of essential oil diffusers which all essentially reach the same goal albeit in different ways. Here, we will explore the various kinds of diffusers and what sets them apart from one another.

Nebulizing Diffusers

These diffusers work by creating a pressured mist that disperses the oil particles into the air. Nebulizing diffusers do not require oil or heat which makes them a low maintenance choice for any spa that needs to diffuse essential oils.

Ultrasonic Or Humidifying Diffusers

These diffusers use ultrasonic vibrations to break up mist into fine particles which are then released into the air. For this type of diffuser, you need to dilute the essential oil with water so that the ultrasonic vibrations can effectively release the mist into the air.

Evaporative Diffuser

In this type of diffuser, a small fan is used to turn the essential oil into a gas which evaporates into the air. However, as the evaporation occurs, the essential oil loses some of its potency so this type of diffuser is more appropriate if you just want the presence of the aroma in the air but aren’t aiming for the essential oil benefits.

Heat Or Electric Diffuser

In heat or electric diffusers, essential oil is turned into a gas by heat. Because there is no fan involved in these diffusers, they are silent which may be desirable in a spa setting. However, the heat can also change, strengthen or weaken the properties of the essential oil so this is something to keep in mind. What effect the heat ultimately has on the oil will depend on the properties of the oil which you are using.

Considerations When Choosing A Diffuser

There are certain considerations and safety measures you should consider when choosing an essential oil diffuser. For instance, diffusers which use water can grow bacteria if they are left sitting and not cleaned. Second, if anyone in a spa room which is using an essential oil diffuser experiences a headache, sore throat or breathing tightness, they should be taken out of the room to fresh air. A small percentage of people may have allergies or bad reactions to certain essential oils. Finally, the device itself should be kept out of the reach of small children and pets and pregnant women should only be around essential oil diffusers with their doctors permission.

Cleaning And Maintaining Oil Diffusers

While oil diffusers do not need to be cleaned after every use, they should be cleaned regularly. To clean them, use natural soaps which you thoroughly remove from all surface areas. If the diffuser has a mister, the head of the mister can be cleaned with rubbing alcohol and a q-tip. Remember to avoid using any harsh cleansers when cleaning diffusers.


Essential oil diffusers can be a great way to add fragrance to any of your spa including the reception area. With a little bit of caution, it should be a relatively low maintenance, inexpensive way to spruce up the environment. There are a number of essential oils with documented benefits and most have little to no drawbacks. Therefore, do a little research about which essential oils might work best in your spa and buy a quality diffuser to release it into the air.
