What is an Essential Oil Diffuser? Why do you need one?

First, what are essential oils?

Essential oils are concentrated liquids extracted from various plants. They have been used for thousands of years for spiritual and emotional uplifting, cosmetic purposes and physical healing. Essential oils are one of the best ways to heal many ailments naturally. The best way to reap the benefits of the large variety of essential oils is to use an essential oil diffuser.Lavender for essential oil - diffusers

What is an Essential Oil Diffuser?

An essential oil diffuser is basically a small device that is used to disperse the wonderful fragrances of essential oils throughout your home. In my opinion, diffusing essential oils is the best way to receive the natural healing benefits of the oils. There are many different types of essential oil diffusers, and it is important to know how each one works. There are candle diffusers, electric heat diffusers, fan diffusers, and nebulizing diffusers, all explained below.

Candle Diffusers

A candle diffuser simply uses a tea light candle to heat up the essential oil placed in a dish above it. They can be found in many different styles and are usually made of metal, porcelain, or ceramic. Essential Oil Candle Diffuser

Candle Diffuser Pros

  • easy to use
  • inexpensive
  • aesthetically pleasing
  • silent
  • no electricity or batteries required

Candle Diffuser Cons

  • burns oil quickly
  • most oils do not diffuse strong enough for healing
  • heat can destroy some elements of your essential oils, making them less effective or ineffective

I personally prefer other types of essential oil diffusers and would not recommend a candle diffuser for healing with your essential oils. If you are left with no other choice, you can find a nice Soapstone Diffuser here.

Electric Heat Diffusers

An electric heat diffuser plugs into an outlet and heats the essential oil to disperse it throughout the room.Electric Aromatherapy Diffuser

Electric Heat Diffuser Pros

  • easy to use, just place oil in and plug it in
  • easy to clean
  • diffuses oils strongly
  • inespensive

Electric Heat Diffuser Cons

  • some have said that certain oils do not diffuse well
  • heat can destroy some elements of your essential oils, making them less effective or ineffective

Using any diffuser that uses heat to diffuse your oils is not the ideal way to use essential oils, therefore I do not recommend heat diffusers. Some will still provide nice fragrances throughout your home, but will likely not provide the healing benefits. If you are unable to purchase a diffuser that does not use heat, I would recommend a Wyndmere diffuser, because it is simple and inexpensive.

Fan Diffusers

You can find many different types and styles of fan diffusers. You simply place your essential oil on a pad or tray and an electric fan disperses the fragrance throughout the room. Spa Scenter Essential Oil Diffuser

Fan Diffuser Pros

  • many varieties to choose from
  • does not use heat
  • certain brands disperse oils throughout a large area
  • can be electric or battery operated

Fan Diffuser Cons

  • some can be noisy
  • most require purchasing replacement pads or other accessories

After a nebulizing diffuser, a fan diffuser would be my second choice for my essential oils. If you decide to go with this option, I would recommend a Spa Scenter Diffuser, which is a fairly quiet model. This diffuser includes 5 reusable pads and disperses oil nicely. Although the pads are reusable, they are a little hard to get clean, and more than likely you will need to purchase replacement pads. If you are interested, you can find one here for a great price!

Nebulizing Diffusers

There are many different types of nebulizing diffusers, and this type is by far my favorite for diffusing my essential oils. Nebulizing Diffusers take the essential oil and break it down into separate molecules before dispersing it into the air. These diffusers use a cold air pump and an atomizer to nebulize the oil into a powerful vapor. Nebulizing diffusers are by far the most therapeutic and powerful way to diffuse your essential oils. The pure oil vapor that dispenses from the diffuser will have many healing benefits. With so many types of nebulizing diffusers out there, I chose 3 brands to review.

Green Air Vapor Diffuser

ProsGreenair Essential Oils Diffuser

  • inexpensive
  • lasts about 6 hours before refilling
  • does not use heat


  • cheaply made
  • a pain to clean (must be cleaned often)
  • does not include separate cup to place oils and water in
  • must use water (not ideal)
  • not meant to be used with citrus essential oils
  • many have had their device stop working shortly after purchasing 

Out of the three nebulizing diffusers I review, this would not be one I recommend. The only reason you should choose this device is for the low price. Just be prepared to return it in case it breaks down on you. You can find it here for $26.26.

Whisper Silent Misting Diffuser

This diffuser is technically an ultrasonic vaporizer, so it does not exactly qualify as a nubulizer, but I decided to include it anyway. Ultrasonic diffusers are very similar to nebulizing diffusers, but not quite as powerful.Whisper Essential Oil Diffuser


  • uses less oil than some diffusers
  • good quality
  • uses cups for oils (keeps oil from destroying mechanisms in device)
  • quiet
  • can diffuse even the thickest of oils (which cannot be used in most diffusers)
  • diffuses up to 1,000 square feet


  • uses flimsy cups, which are pricey, and need replacing often
  • must clean after each use
  • must use water (not ideal)

Overall, the Whisper diffuser is a great diffuser and can be found here for $94.89. Just prepare to spend the money buying the replacement cups. I am also not too fond of mixing essential oils with water.

Aroma-Ace Essential Oil Diffuser

ProsAdvanced Aromatherapy Essential Oil Diffuser

  • no heat or water (preserves all healing properties of essential oils)
  • easy to use
  • excellent quality
  • diffuses oils nicely
  • easy to switch between oils (put your bottle directly on the atomizer)
  • comes with empty bottles for mixing oils
  • built in timer


  • some say noisy (think fish tank)
  • can use oils quickly if turned up on high
  • takes some soaking time to clean

After many hours of research into essential oil diffusers (and many trials), I finally found what I believe to be the perfect diffuser. This diffuser disperses 100% pure essential oil and does not use heat or water. No replacement cups or pads to buy and easy to use. This diffuser is by far the best and is the only diffuser I use now. Well worth the investment! If you have been looking for the perfect essential oil diffuser, you can get yours here for only $129.00
