What Is An Essential Oil Diffuser?


An essential oil diffuser is a device that disperses the aroma of essential oils into the air. When utilizing this device, make sure that you use only pure essential oils. If not, then you might make yourself at risk in breathing chemicals.

Different Types Of Diffusers

You can find more than one type of diffusers on the market. No matter what your choice is, make sure to follow the manufacturer’s instructions in adding essential oils for optimum performance.

1. Candle Diffuser


A candle diffuser is an inexpensive type of heat diffuser. Normally a tea-light candle is used to heat a small bowl of essential oil. Although this method can be used anywhere, the heat may alter the composition of some volatile essential oils.

2. Ultrasonic Diffusers


This type of diffuser uses water and ultrasonic waves to disperse the scent of essential oils into the air. Unlike other types of diffusers, ultrasonic works quietly and works a double purpose in humidifying a room. They also keep the therapeutic properties of essential oils intact.

3. Nebulizing Diffusers


Nebulizers can diffuse efficiently but it can’t work on thicker essential oils. Their devices can be difficult to clean, too. However, they’re like ultrasonic diffusers, nebulizers which can keep the therapeutic elements of essential oils.

What To Look For


1. Working Time

For long lasting fragrance, you need a long working time. Most diffusers can run effectively up to six hours. The longer the hours, the better.

Alongside the working time, the water capacity is also important to determine the estimated amount of water and oil diffused. Such amount diffused can be determined by dividing the water capacity with the operating time. For example, a 200 ml capacity and five hours working time generate an estimated diffusion of 40 ml per hour.

2. Adjustable LED Light

Most diffusers have an LED light feature to serve as lamps in a room. As possible, look for a higher number of light modes to fit any occasions. A soft light can be used to create a relaxing mood in your room. More light options, the better.

3. Ultrasonic Technology

The best essential oil diffuser should have a whisper quiet operation so it won’t bother you when you sleep. The noise level should be low as possible to have a quiet operation. Most ultrasonic models work silently, making them a preferred choice for aromatherapy fanatics.

4. Special Features

A good essential oil diffuser should have a lot of settings and options for versatility. An automatic shutoff feature is highly desirable to prevent the diffuser from burning out. A timer is also helpful if you want to run your diffuser for a specific time.

5. Warranty

One of the most important features that you should consider when buying any product is a long warranty. Sometimes, the product may be defective when we receive it so having a warranty gets your product viable for replacement. A longer warranty is much preferred.
