What Is The Best Essential Oil Diffuser? -Top 10 Reviewed

best essential oil diffusers

You have probably gone to a friend’s place before and the instant you breathed, there was a sensation, calming, that you closed your eyes and allowed the air to flow freely through you. You did not just fall in love with the aroma but also wanted it. Aroma triggers the brain to produce certain hormones, relieve pain or boost moods. Apart from the delightful calm and relaxing effect it gives, there are also health benefits – psychological, mental and emotional. Essential Oil Diffusers help disperse the aroma given off by essential oils into the air. However, the process of getting the best oil diffuser that will work best for you can be tiring. While some diffusers are more suitable for large rooms, some work best in a small-sized apartment, and that is a factor amidst others. That is why I have put together the top ten diffusers on the market, including the pros and cons to guiding your choice.

Difference between diffusers and humidifiers

Because humidifiers and diffusers act alike, many tend to confuse them for each other. Humidifiers give off mist to preserve the air moisture. Humidifiers are suitable for people who want to prevent dry skin or lips, especially during dry winter months. The moisture is required more during dry weather conditions and during the heat of fall. They dryness that comes with these climates can cause issues like skin dryness, viral, and bacterial problems for some people. People use humidifiers to treat cold symptoms, flu or sinus congestion. Humidifiers are also efficient for those with allergies or asthma, providing fast relief. Furthermore, it helps to lessen snoring. The humidifiers produced for sale in the market are not able to diffuse essential oil. If you intend to optimize the effect of essential oil by dispersing it, then I would recommend you go for a diffuser, properly called essential oil diffuser.

Diffusers, on the other hand, deliver only essential oil and are designed specifically for aromatherapy. There is more. Some diffusers can also function as a humidifier, and can give off the cooler mist. They come in different shapes and sizes and give aroma to the area by vaporizing mists with essential oil.

What factors determine the best Diffuser for Essential Oils?

In choosing what would pass as the best product, there are factors that should come into play. Every diffuser brand will state that it is better than its competitors are – that remains for you to decide. The essential point is that it diffuses essential oils. Of course, it would be useless if it does not do what it says, and what I look for are the features that allow for ease of use, coverage, and intended use. These are questions you should ask: Why am I buying? For the aroma, or the health benefit? Where will I use it? Home or office? A large or small room? Look at the following features.

Capacity: The capacity of the diffuser determines how much of Essential oil it can carry. Diffuser with large holding capacity reduces the refilling frequency. This will ensure you have the time to do other things without worrying that your diffuser will run out of oil soon.

Auto-shutoff: When the diffuser runs out of water or oil, it should automatically shut off to prevent the unit from burning up.

Timer: With this feature, you can quickly decide how long you want the diffuser to run. This saves you from having to periodically check the time before you shut it off. While some come with the auto timer, some have the feature of running for a period before going off.

Coverage area: The coverage area of a diffuser tells how further it can reach. Some diffusers are designed to cover the entire house or office, and some work well in a small area. If you want the diffuser to reach beyond your living room to every corner of the house, you would be better off with a diffuser with more square feet reach.

Ease of cleaning: A good diffuser should allow for easy cleaning. Cleaning could be done with water, dish detergent or alcohols – whichever you prefer. It should be conveniently done without damaging the unit.

Essential oil replacement: If you were the type that uses different oil with a change in weather or daytime, then you would find this to be an essential factor. It is important that changing oils do not become a herculean task.

Customer service and reviews: Negative feedbacks are disastrous for any company. When choosing any diffusers, I try to check what other buyers are saying and allow that to guide my decision. A good diffuser brand should offer aftersales support and at least 3-months warranty.

Different Types of Diffusers

There are four types of diffuser based on the mode of operation. Each diffuser works differently and is selected according to user’s need or personal preferences.

Nebulizing Diffusers

I consider this the most powerful and efficient of all the diffusers. In fact, it is popular than the rest. To diffuse oil, it does not require heat nor water. For its operation, it employs the kind of technique used in perfume atomizer. The in-built atomizer functions like the pushed top of a perfume bottle. The air produced at the base of the diffuser pushes up the air from the bottom to the top of the tube. The constant airflow releases the oil into the air in fine sprays. The therapeutic grade of oils is perfectly retained, and I would personally recommend this kind of diffuser over the rest. Asides from preserving the quality of the essential oil it diffuses, it also easy to maintain and does not require constant cleaning.

The sides some users may not feel comfortable with are the sounds it makes during operation (it is not that loud) and the quick oil exhaustion. It also uses more oil than the rest, but aside that; it is still the most recommendable type of diffuser, especially around sick people who require a constant stream of essential oil.

Ultrasonic Diffuser

Its mode of operation is somewhat similar to the nebulizer. It also creates a fine mist, however, unlike nebulizing diffusers, they require water to create the cool mist. Due to the water mixture, the concentration of the essential oil is reduced. Ultrasonic diffusers can also function as humidifiers especially during winter or in dry climates. Almost any kind of essential oil can be used with this diffuser, apart from citrus essential oil because it could corrode core elements of the diffuser.

When compared with nebulizing diffusers, ultrasonic diffusers are less expensive but not as efficient. They also require constant cleaning and are harder to maintain.

Evaporative Diffuser

Evaporative Diffuser: As the name says, this unit uses evaporation to diffuse essential oil. A fan provides air through a filter or pad into the area where the essential oil is held. The air blown by the fan makes the oil evaporate. The effect is that there is a fast dispensation of aroma into the air. The therapeutic effect of the oil is however reduced by the imbalance that resulted from the continuous air flow. It is the most efficient whenever you quickly need to change or add to the aroma of a place.

Heat Diffuser

Unlike the evaporative diffusers, heat diffuser uses heat to diffuse oil into the air. A carrying chamber holds the oil to be diffused, and then when heat is applied to the base, the oil diffuses. The procedure is simple. Pour the oil to be diffused on the tray, then light a candle or whatever your preferred heat source is, and let the oil diffuse. It works effectively for small rooms and is noiseless. There are, however, some side effects such as the risk of fire hazards, reduced oil diffusion effects, and altered therapeutic effect of the oil.

Conclusion

Getting the best diffuser for your home, office, or business does not necessarily have to be hard work. Daily, people, are always finding a way to stay healthy, and the solution provided by natural sources like essential oils cannot be overstated. It may be a good idea that you create a checklist of your preferences and match it with the device that best meets your diffusing needs.

Just want to mention that the brand name of the No.1 essential oil diffuser is not Innoo Tech, it should be InnoGear.
