The doTerra Petal Infuser is the best we’ve been able to find… anywhere. This compact infuser runs for four hours which makes it perfect for filling the room with the perfect scent during the day. It has a surprisingly wide spread despite its relatively diminutive size as well. Most people find that it can spread a scent through multiple rooms without much trouble as long as the doors are open. While it does contain plastic, the build-quality is fantastic and the plastic is extremely resistant to the more corrosive oils which you might want to utilize.

It also has some fancy LED lights which can either cycle through colors or be locked on your favorite, depending on your mood.

Of course, this immense potential comes with the caveat of a very high price for an essential oil diffuser, so it’s up to you to decide if it’s worth the investment.

Pros and Cons
  • 330 cubic feet of dispersal
  • Very simple to use
  • LED lighting
  • High build-quality
  • Easy to clean
  • Expensive
  • Short run time at 4 hours

What Type of Essential Oil Diffuser Do I Need?

There are a few different types of essential oil diffuser on the market, and while they all do pretty much the same thing there’s quite a bit of difference in the way they diffuse the oils.

Ultrasonic diffusers work through frequencies, dispersing a fine mist into the atmosphere without actually having to heat the oil itself. This makes them optimal for aromatherapy and receiving the benefits of the oils you’re using since the components of the essential oil are virtually certain to remain unchanged while the diffuser is in use.

Heat diffusers work by slightly heating the oils in order to cause them to evaporate. These are really only recommended for smells, since they’ll alter the delicate chemicals contained within the essential oils and can render medicinal properties inert.

Evaporative diffusers use a small fan to push out the essential oil/water mixture as a vapor. They’re great for portable devices in your vehicle, but they fall short due to one simple fact: heavier oils are going to disperse much slower than lighter oils which makes their usage unpredictable.

Cold air diffusers use a fan to blow the oil into a nebulizer. They’re rather efficient but they can’t handle heavier oils, and they’re noisy and hard to clean.

For most people, we strongly recommend an ultrasonic diffuser unless you need something small for your vehicle.

Deciding on Your Diffuser

Deciding on Your Diffuser

Not all diffusers, even within the same category, are created equal. Indeed, there’s a ton of cheap products out there which are made to mimic the better quality diffusers on the market.

When you’re looking to finalize your decision, be sure of the following:


The best diffusers are going to be made of ceramic or polypyrelene which ensures the longevity of your item. Essential oils can be corrosive to cheap plastics and that’ll lead to an early breakdown… and a huge mess.

Diffusing Area

You’ll want to go as high as possible with this, with one caveat: if the diffuser doesn’t have a way to reduce the output. It’s pretty rare that you’re going to encounter “too much” oil in the air but it can On the other hand, some cheaper diffusers simply won’t have enough power for larger rooms.

Water Capacity

The capacity of your diffuser is going to determine the amount of time it can run for before you need to reload. You can easily figure out how much oil you need once you figure out the amount of water contained within and the estimated operating time.

Size and Shape

Since it’s likely to be sitting on a desk or end table, most people will want to make sure that the diffuser they’ve decided on is able to fit and look good. Take a look at where you think you’ll want to be placing it to figure out which seems to be the best for you.


Some diffusers have some pretty attractive extras. Whether it’s LED lighting that changes colors or programming options these can make all the difference when it comes to attractiveness and ease of use.

Once you’ve got all of those qualities in order, you simply need to figure out which one will best suit your desired usage at the end of the day.

Using Your Essential Oils

Using Your Essential Oils

The essential oils that go into a diffuser can actually have some benefits for your health over time. This is especially true if you’re working with an ultrasonic vaporizer which will mist the volatile components of the oil without causing any damage to them.

There are simply too many varieties of essential oil for us to list them all here, but some of the most common are also some of the most beneficial for the user.

Lavender oil, for instance, is reputed to have a strong calming effect. The delicate, flowery scent is certainly pleasing and many people find it to have anxiolytic qualities.

Peppermint oil is often used for headaches and has a cooling but refreshing effect. It also stimulates alertness, which makes it great for use by those who work at home.

Eucalyptus, on the other hand, is great for clearing a room of bad odors and can help with respiratory issues. This crisp smelling oil is one of the most common utilized in any type of aromatherapy.

Of course, you can mix and match with a wide variety of oils. One of the cool parts about a diffuser is that it often eliminates the negative effects that can occur with the repeated administration of some essential oils.

Using most diffusers is pretty simple: add water to capacity and then put in as much oil as directed. In some diffusers you can get away with more oil than recommended, but try not to make a habit of that.

After that, turn it on, lean back, and enjoy the smells and benefits of your new device.


Essential oil diffusers are on the fast track to replacing scented candles as the best way to keep your home smelling clean and crisp. There are a lot of them on the market, but we’ve made sure to only show you those which truly stand out from the pack.

They’re low in cost, high in utility, and one of the best ways to ensure that your home remains smelling wonderful with the simple press of a button.
