Diffuser Ultimate Buyer’s Guide

Nowadays, it’s easier than ever to purchase essential oil diffusers. In the past, only professional aromatherapy studios could benefit from their use. Now, with the progression of modern technology and the decrease in prices due to mass production, everyone can get their hands on such a diffuser. It’s the perfect thing to make your home feel even more comfortable.

If you are looking for such a product, you should know that there are four types of diffusers:

  • Nebulizer diffusers
  • Ultrasonic Diffusers
  • Heat diffusers
  • Evaporative diffusers
Nebulizer diffusers

Outline nebulizer diffusers

The nebulizer essential oil diffuser is one of the most powerful out there because it doesn’t need heat or water to diffuse the oils.

Nebulizing diffusers have a technology that reminds of perfume atomizers. You’ll have a flow of air that will get the essential oils out of the tube. At the same time, there will be a continuous airflow that will spread the particles into the room.

This natural diffusing procedure keeps the healing properties and purity of the oils. That’s why professional aromatherapists prefer these nebulizers.
Ultrasonic diffusers

Ultrasonic diffusers

An Ultrasonic diffuser needs water to function. Once you connect the device to a power source, the disks within will start vibrating at an ultrasonic frequency. The water and essential oil blend from the reservoir will then become a cool and fine mist.

Since they function with water, these diffusers can pass off as humidifiers as well. It’s definitely a good thing that this device is so versatile. Still, the bad part is that the oils will be diluted in water, so the scent will not be as intense.

These types of diffusers are also some of the most popular out there. This is why you’ll notice that they are widely produced.

Heat diffusers

Heat diffusers

As the name suggests, heat diffusers make use of heat to evaporate the essential oils into the air. They usually consist of a tray that has a candle under it, providing enough heat for the oils to evaporate.

The downside of the heat diffuser is that the aromatic effect is rather short and that some of the therapeutic effects within the essence are destroyed during the heating process.

Evaporative diffusers

Evaporative diffusers

The evaporative diffuser will spread the scent of the essential oils in the room using a fan. That fan will blow into the pad or filter holding the oil, slowly spreading it into the environment thanks to the breeze.

The downside is that the evaporation with these kinds of diffusers is rather slow – therefore decreasing the therapeutic effect.

How to diffuse essential oils and how to use essential oil diffuser?

The process of diffusion is simple and straightforward. Every diffuser should come with a user’s manual that explains the process of evaporation. At the same time, it will tell you in detail how the device functions. With that being said, most ultrasonic diffusers work on the same principals.

Here are 7 general steps that will activate your ultrasonic diffuser safely:

  1. Remove the lid to expose the water reservoir.
  2. Fill the water reservoir with the appropriate amount of water. Don’t overfill it; too much liquid may lower the diffuser’s efficiency.
  3. Add a few drops of your favorite essential oil blend to the water. Remember, some ultrasonic diffusers cannot bear the strength of citrus essential oils.
  4. Securely close the lid to prevent the spillage.
  5. Plug the device into the source of power. Most diffusers require USA 110/120-Volt outlet (check your user’s manual for accurate information).
  6. Press the power button and set the diffuser on the desired mist mode.
  7. It is recommended to clean the diffuser after every use to get rid of the buildup that may shorten its life expectancy. Every diffuser should include maintenance instructions.
WARNING: If you own a pet, consult with the vet before setting an aromatherapy device in your home. For some animals, evaporated essential oils may be hazardous.

What are the best essential oil diffuser recipes?

Every diffuser has different water reservoir capacity that should always be taken into consideration when adding essential oils. Here is a table that will help you create appropriate water: oil ratio.

Water Reservoir Size (ml)Number of Essential Oils (drops)
100 ml3-5
200 ml6-10
300 ml9-15
400 ml10-20
500 ml15-25

Here are 5 best essential oil diffuser recipes:

  1. Morning freshness: 4 drops of wild orange essential oil + 4 drops of peppermint essential oil
  2. Summertime tranquility: 3 drops of grapefruit essential oil + 3 drops of lavender essential oil + 2 drops of lemon essential oil + 2 drops of spearmint essential oil
  3. Sweet dreams: 3 drops of lavender essential oil + 4 drops of cedarwood essential oil
  4. Get focused: 2 drops of peppermint essential oil + 2 drops of cinnamon essential oil + 1 drops of rosemary essential oil
  5. Take it easy: 4 drops of lavender essential oil + 2 drops of cedarwood essential oil + 2 drops of wild orange essential oil + 1 drops of Ylang Ylang essential oil

Each amount can be modified according to your preferences – and obviously, your taste in essential oils. These are simply some examples to guide you.

How to make DIY essential oil diffuser?

If you haven’t found your very own best essential oil diffuser among the given list of essential oil diffuser reviews, just remember: the doors of the DIY world still offer plenty of alternatives you can create by simply putting your craft skills to use.

Here is a 5-step instruction list on how to make the simplest DIY essential oil diffuser:


  • Essential oils of your choice
  • Sweet almond oil
  • Diffuser reeds
  • Glass or ceramic jar with small opening (for instance, a perfume bottle with small neck)


  1. In a clean glass or ceramic jar add the ratio of 30% essential oil to 70% sweet almond oil.
  2. Swirl the jar to mix the oils thoroughly.
  3. Place 8 to 12 diffuser reeds into the jar and let the oil travel up the reeds in order to fragrance the air.
  4. When the scent starts diminishing, simply flip the reeds upside down.
  5. Repeat the process once the oil is gone.

How do you clean your essential oil diffuser?

Cleaning your essential oil diffuser is rather easy. You start by pouring some water in the water tank, about halfway through. However, instead of adding essential oils, you add 10 drops of white vinegar. This will help get rid of the oils that got stuck to the diffuser.

After 5 minutes, you may drain the diffuser and clean the tight spots with a cotton swab that has been dipped in vinegar. This way, you will make sure that no other spots were left dirty.

Repeat the process with some clean water, to remove the vinegar. In the end, use some cotton swabs or a dry cloth to dry the diffuser properly.


Overall, you can see now that the market has oil diffusers for each type of person, regardless of your needs and tastes. Choosing the best essential oil diffuser for you is as easy as selecting which pair of shoes to buy next.

Before purchasing a new essential oil diffuser, ask yourself the following questions:

  • What room style design do I have to match with the diffuser?
  • Where will I be placing the diffuser?
  • Does it need to scent a large room or just a small one?
  • How long do I need the diffuser to function every day?

These questions will help you find the perfect oil diffuser for you. Based on popular reviews, the TaoTronics oil diffuser seems to be the most popular one, since it’s stylish, efficient and portable.

Still, the other essential oil diffusers are just as effective. Customers tried them, and they were all very pleased with the results they got. The right oil diffuser will spread the essential oil scent throughout your home, making it smell fresh while relaxing you in the process.


  1. Do you think it is safe to leave it on overnight?

  2. I like the oils very much, but my husband says it gives him headache. Do you think there is a blend I can try that would fit him?

    • Try to ask him what kind of smell he prefers, and then try an oil, and, maybe, add fewer drops to you diffuser so that the blend wouldn’t be too strong.

  3. I bought a diffuser recently…and something is wrong. I add the oils as in the instruction, but the smell is really bad..it doesn’t smell anything like lavander, even though is says so on the bottle. What can the reason be here?

    • I know, I have the same problem, I was using the orange oil…but it smelled like a multivitamin synthetic pill…

    • I believe the problem is that you are using a poor quality oil. Some brands add synthetic contents to make the oil cheaper. Only buy from trustworthy dealers and always check the contents on the bottle!

  4. I use a car diffuser. I don’t have to clean it too often, but when I do, should I use just water (in this case it takes a long time to clean the sticky oil of off the walls) or can I use regular soap?

    • Hello, Jenny! You don’t need to use soap to clean your diffuser. You can clean it with a mix of water and venigar or soda!

  5. I’ve been using the oils for a few years now, and a month ago I noticed that my cat started sneezing. Do you think it is the oils or somethign else?

  6. Thank you for the review! I set my mind on ultrasonic diffuser and it works great for me!

  7. I was wondering if I can use the oils in my car when I drive my pregnant wife to doctor’s appointments. She sometimes gets sick on the road because of the bumpy road and hot weather.

    • Well, firstly, consult your doctor about using oils during pregnancy, their might be some allergic reactions. If there is none, then I would suggest using lemon blend.

  8. Amazing review! Thank you so much.!

  9. Thank you so much for this review! It really helped me choose a diffuser, this market can be really confusing at times.
