Things To Lookout For

Consider the following factors before selecting an essential oil diffuser that’s right for you:

Size Of The Essential Oil Diffuser

The functionality of an essential oil diffuser doesn’t change with the size of the product, but it’s something to consider.

The smaller the diffuser, the shorter the run time before you’ll need to re-fill the water reservoir.  For some people, running their essential oil diffuser for a couple hours is enough to spread the scent to their desire, for others, they might want to have the diffuser run continuously throughout the day or night.  Also, the smaller the size of the essential oil diffuser, the less “reach” it might have for the scent distribution.  When purchasing, you should look at the size of the diffuser along with the strength of the mist and if the strength can be adjusted.

Quiet While Running

An essential oil diffuser is often used to help create a calm and relaxing environment.  That probably means you don’t want a machine that makes a racket while generating mist.  So, unless the noise is intentional (like a built in noise machine, which we saw, but noticed a huge price jump, and didn’t include in this list) you probably want a quietly running essential oil diffuser.  Most diffusers claim to be quiet, but reviews will tell you if that claim is accurate.

Different Mist Strength Options

The stronger the mist strength, the stronger the scent if you elect to use an essential oil in your diffuser.  So, if you’re sensitive to scents, or you simply don’t want a smell that’s strong sometimes, being able to choose the strength of the mist will be something to consider when selecting a product.

Timing Features

Most essential oil diffusers have an auto off feature when the reservoir runs out of water.  That said, if you don’t want to run the diffuser continuously until it simply runs out of water, being able to pre-set times for the machine to run will allow you the peace of mind that it’s running when you want.  There’s a wide variety of timing features, ranging from a couple windows (3 or 6 hours, for example) or a ton of options in other models.

Lighting Modes and Colors

Some people sleep serenely when a gentle blue light glows in the corner.  Other people might absolutely hate any and all light when they’re trying to sleep.  The variety of lighting options in essential oil diffusers is wide spread.  Some diffusers come in a certain color (blue, for example) so, only choice would be light on, or light off, which would glow in the color of the diffuser itself.  Many other essential oil diffusers have LED lights, meaning there could be multiple color options and intensities.  Some stay the color that you choose, others meld from one color to another.  Knowing what will help you and your space be as peaceful as possible might impact which essential oil diffuser is the best fit for your needs.

Cleaning The Essential Oil Diffuser

Recommendations for frequency of cleaning varies by product, but wiping the inside of the essential oil diffuser with a damp cloth after each use can help to reduce any clogging and ensure it runs well and is able to create and diffuse mist.

The type and quality of essential oil a person uses can also impact the way a diffuser runs and the length of use.  It is recommended that 100% pure essential oils are used in diffusers.

Therefore, buy a unit that has fewer but removable parts —pull them apart to convenient and efficiently clean the essential oil diffuser.

Price & Warranty

An essential oil diffuser can cost you as little as $25, which can help to create a calm environment, but likely for a smaller sized space.  There will also be limited features for the less expensive models.

As features increase, and the quality of the product is enhanced, the pricing can also increase.  The fancier models can cost up to $50 dollars

Remember, buying a good essential oil diffuser is a fixed cost; you still have to pay for the variable cost of essential oils.  As stated, 100% pure essential oils is recommended, which can range in price.

Also, check the warranty for your essential oil diffuser before you buy it and make sure it’s valid.

Bells & Whistles

Apart from the considerations mentioned above, look for some extra features that can enhance your essential oil diffuser user experience.  These would also help you in reaching a buying decision.

Here are some of the much advancement seen on newer essential oil diffusers.

  • Smart Connectivity – The diffuser is able to connect with WiFi and a downloadable app or other smart home technology like an Amazon Echo. This allows you to control settings through the use of an app or a voice command
  • Auto-Shutoff — It’s no biggie if you forget to shut off your essential oil diffuser before leaving the house if you have a machine with an auto-shutoff feature, which turns off when the water reservoir is empty
  • Mist Strength — Being able to select how strong the mist strength is in your essential oil diffuser means you also have control over how intense the scent is based on preference
  • Lighting Options — Being able to choose the type of light your essential oil diffuser emits, the intensity of that light, and the color of the light are all features to consider
  • Audible or light-based alerts to inform that the essential oil diffuser has finished its timed cycle, or has run out of water and needs to be re-filled.

Frequently Asked Questions (FAQs)

What Is The Lifespan Of An Essential Oil Diffuser?

A high quality essential oil diffuser should last for at least a couple of years, but at the end of the day, it depends on how extraneously you use it. Some high-quality appliances can last for years – whereas others may not even last the warranty period.

Are Essential Oil Diffusers Easy To Clean?

Yes, they are — turn off and unplug your essential oil diffuser.  Gently wipe out the water reservoir with a damp, clean cloth.  Follow the product instructions for cleaning other pieces of the diffuser.

Is Using an Essential Oil Diffuser Safe?

The auto off feature for most essential oil diffusers mean they are safe to use without risks to the machine or the home.  That said, specific types of essential oils might not be the best option to use in a home with pets.  Users should review any potential side effects for pets in their home before using specific types of essential oils.

What Type of Water Should I Use in My Essential Oil Diffuser?

To reduce the risk of corrosion, it is recommended that you use unfiltered tap water.  Be sure to read the specifications listed in the directions of your essential oil diffuser to learn additional information about water type for use.

How Much Essential Oil Should I Use?

It depends on the water capacity of the essential oil diffuser along with the intensity of the scent you’re hoping to achieve.  Read recommended instructions thoroughly and remember, you can always add a few more drops, but you can’t take drops away once they’re used, meaning it’s best to start on the lower end of the spectrum and gradually add drops of essential oil until you reach the desired scent intensity.  Also note, certain essential oils might be more intense in scent than others, so usage amount might vary by essential oil.
