Factors to Consider When Buying the Best Essential Oil Diffusers

1. Type 

There are three main types of oil diffusers: passive, ultrasonic, and nebulizing. They create a fine mist but work a bit differently. Passive models don't use water or heat; they are powerless. They use porous ceramic to emit essential oils naturally into the air. Ultrasonic models are the cheaper option that creates vibrations that break the essential oils down and disperse the individual molecules into the air. Conversely, nebulizing essential oil diffuser disperses more potent, undiluted essential oils into thin air using pressurized air.

2. Lighting

Many essential diffusers provide ambient LED lights or twice as night lights. When buying an essential diffuser, this becomes a personal preference, therefore if you don't want a light, ensure the diffuser you want to purchase doesn't have one, or you can turn it off.

3. Reservoir capacity

Essential diffuser water capacity can run anywhere from 3.4 fluid ounces (100 millimeters) to more than 33.8 fluid ounces (1 liter) of water; however, the average water tank holds around 300ml. You may want a larger water tank capacity if you don't want the hassle of refilling the water often or if you need your essential diffuser to operate for a long time in a large space.

4. Intensity

If you are looking for the best essential oil diffuser with a stronger scent, buy the nebulizing diffuser models. This device vaporizes the essential oil drops without using any heat before dispersing the smell in a fine mist into thin air. These models are more expensive than regular diffusers but can be worth your money if you find the regular diffusers less effective.

5. Cleaning 

These models benefit from standard cleaning; however, ultrasonic models are more difficult to clean since they use essential oils and water. Water makes the gadget more vulnerable to mold, and tap water can leave calcium inside the gadget. We have researched the best overall picks and found essential oil diffuser models that look great and work well to make your space feel more relaxing.

6. Material

When shopping for the diffuser, consider the material. Most people will go for the common semitranslucent white plastic choices. However, you can find essential oil diffusers in other materials such as porcelain, ceramic, fake, or even real wood. Usually, better materials are likely to appear on pricier models.

7. Humidity and mist settings

Many diffusers double as a cool-mist humidifier. This feature can be a great two-in-one option, especially if you live in a dry climate.

Do you want an intermittent mist or a continuous cool mist that operates for hours for diffusing essential oil drops on mist settings?

8. Automatic shut-off

Even if you are not a forgetful person, selecting an essential oil diffuser with auto-shutoff is a smart move. In case you forget to shut down your diffuser when there is a little water left, it can end up overheat and fail.

9. Run time

Many large and medium diffuser models have a timer that will turn off the essential oil diffuser after 60 minutes or a few hours. This function lets you run the gadget several times without refilling the water. When buying a diffuser, these are the questions to consider; how long do you want it to run?

Since nebulizing diffusers use only essential oils, they run for a shorter period of about 10 minutes at a time. Ultrasonic diffusers require a mixture of essential oils and water, which allows them to operate for about 30-60 minutes at a time. (you should drain and wipe out your diffuser gadget every few days if you are not using up all the water).

Frequently Asked Questions on Best Essential Oil Diffuser

It is important to use diluted essential oils as it will help you keep your diffuser safe from ugly and untimely corrosion hence increases its longevity.

2. What kind of water should I use in the essential oil diffuser?

Since water is the base substance to dilute the essential oils, you must be perfect in picking the water. Ensure you do not use distilled water. We recommend using unfiltered tap water or the gadget to be cleaned because the essential oils cling to ceramic sensors or discs.

5. What should I consider before purchasing an essential oil diffuser?

You should buy the best and high-quality diffusers. It is not a must for it to be a heat diffuser as it only diffuses the aroma in your room. You need to buy the one that will help you break down the oil into the finer mist. Furthermore, ensure it does not rust with a little use and proposes great usability with their features.

6. Is it safe to inhale the mist from the essential oil diffuser?
