Oil Diffusers: A Buyer’s Guide

What are essential oils?

Essential oils are natural oils derived from botanical sources that have traditionally been used as ways to provide relief to a myriad of issues and also serve as a means of soothing and healing the body naturally. These oils can be sourced from trees, fruits, vegetables, and there are a few that come from roots.

These products can be used for aromatherapy, placed in a bath, or some can even be ingested in order for you to receive health benefits. In fact, these oils are so effective that many have been used for thousands of years around the globe. These oils are difficult to replicate synthetically, which is why they are so valued in many global communities.

What are some common essential oils used in aromatherapy?

There are literally hundreds of essential oils that are used for a myriad of purposes around the globe, but that being said, the most commonly used are:

  • Rosemary
  • Peppermint
  • Lavender
  • Clary sage
  • Eucalyptus
  • Cedar Wood
  • Cypress
  • Fennel
  • Ginger
  • Geranium
  • Ylang Ylang
  • Rose
  • Roman chamomile
  • Lemongrass
  • Tree tea
  • Frankincense
  • Orange
  • Oregano
  • Basil
  • Marjoram

Each of these essential oils is perfect for making the body feel better, increasing the mood, and providing a general sense of well being. Some smell better than others, but if you’re looking for something to relax, consider eucalyptus or lavender. If you’re looking for something with immediate health benefits, clary sage and chamomile are excellent choices.

How does an essential oil diffuser work?

Essential oil diffusers effectively diffuse essential oil into the air so that you can benefit from them. You simply select a location for the diffuser to work in, add water if the diffuser uses water for the process, and add the oils to the topmost surface of the diffuser. Typically, you won’t need a lot of water to start the process, and over time, the oil will gradually diffuse into the environment, which will produce a pleasant scent and deliver the effects of the diffused oil to anyone in range of the aromatherapy scent.

Are essential oils safe for children to breathe in?

Unfortunately, there are definitely some oils that should be avoided when you have children. Additionally, essential oils should always be kept out of the reach of children due to the fact that they can be toxic to ingest. If you have a younger child under the age of three, it’s a good idea to limit their exposure to many aromatherapy oils since their systems aren’t developed enough yet to deal with all of the minerals inside the produced scent. Some specific oils to avoid are bergamot, cedarwood, cinnamon bark, and carrot seed – many of these oils can cause skin irritation in children if they aren’t diluted properly.

Are there some oils that are safe for kids around the age of two?

Fortunately, there are a few oils that can be diffused relatively safely around toddlers, but as a general rule, never exceed a two percent volume of oil when you’re diffusing around a small child. Effectively, this means that you can usually use about 20 drops per ounce of added carrier oil. Some safe oils in this range are clary sage, black pepper, and frankincense.

What’s a good location in your home for an essential oil diffuser?

As a general rule, it’s a good idea to create an aromatherapy environment where the scent will have the most space to cover. For this reason, many people have a tendency to use their diffusers in their living rooms, and in this room, you can even diffuse while you’re watching your television or relaxing on the couch. You can also diffuse oil with a non-heating diffuser in your bedroom while you rest; many people find that they wake up feeling more refreshed when they wake. There are even stronger products that can work as the best essential oil diffuser for large space homes.

Can you overfill a diffuser?

Sometimes, when you’re combining a few essential oils, you can end up adding a little too much. As a result, you’ll end up having a really potent mixture that may even make you want to leave the immediate area. To solve this issue, you can simply pour the overage of oil into a container and add additional water. Only pour a small amount into the diffuser and diffuse as you would normally.

Should you use carrier oil in your essential oil diffuser?

When you want to extend the life of a particular aromatherapy oil, you can actually employ a carrier oil in order to have a longer aromatherapy session. Carrier oils are oils like olive or jojoba oil that come from natural botanicals similarly to essential oils. The chief difference is that these oils are typically scentless, but have the ability to stretch out the lastingness of the essential oils so that you can enjoy your session for a longer duration.

Can you use a candle warmer instead of a diffuser?

While you can technically diffuse your oils this way, typically, this greatly reduces the effectiveness of the essential oils. In fact, it’s estimated that essential oils become more than 70 percent less effective when you use a candle warmer. It’s important to understand that candle warmers aren’t designed for this use, so it’s best to just purchase an essential oil diffuser when you want aromatherapy.

Can you mix essential oils in a diffuser?

This is probably one of the best features of a modern diffuser – with one, you can mix different carrier oils so that you can combine some of the benefits of both. Additionally, you’ll be able to create some truly unique scents. In most cases, it’s a good idea to mix only the oils from the same grouping of uses – it’s simply a bad idea to mix an oil that’s meant to help you relax with one that’s designed to provide energy.

What are some systems that oil diffusers use to diffuse the scent?

On the market today, you’ll usually find vapor, heat, and ultrasonic essential oil diffusers, and each uses a different system to provide aromatherapy experiences. Here’s how each works:

  • Vapor: These types of oil diffusers use air to pull the oils, which are positioned in the bottom of the diffuser, up through a tube. Once the oils are at the top, they are released as a fine mist that works its way into the air as a vapor. These are unheated diffusers, and vapor diffusers also have the bonus of being releasing fairly concentrated oil into the environment.
  • Heated: If you’re looking to not spend a heap of cash, heated diffusers are very inexpensive. These also have a tendency to come in a variety of shapes and sizes, but in general, you’ll be using a small candle or votive to heat the oil in a small upper platform. These are easy to use, but due to the release of heat, these can also break down the essential oils so that they aren’t as effective.
  • Ultrasonic: As the name implies, ultrasonic essential oil diffusers use sound waves to diffuse the oils into the air. Typically used in conjunction with water, these diffusers cause the oils, which are combined with water, to break down into molecules that are then diffused into the air in the form of negative ions.

Can you set the length of time an oil diffuser diffusers?

If you have a tendency to be forgetful, a good vapor-style or ultrasonic diffuser will sometimes include a timer. In fact, some products even have multiple timers onboard that will ensure that the diffusion process ceases after a preset amount of time elapses. These are typically high-tech diffusers, but many fans of essential oils love these types.

Can your pets be in the room during aromatherapy treatments?

Amazingly, there’s a branch of aromatherapy that’s specifically designed to calm your pet. That being said, never attempt to use an essential oil for your furry friend without consulting your veterinarian; some essential oils can actually cause liver and kidney problems for your pet, so exercise caution. For example, melaleuca oil should never be used in a household with a cat and oils like cinnamon, citrus, and ylang ylang are problematic for both dogs and cats.

Should you clean your diffuser after use?

If possible, your essential oil diffuser should be cleaned at least every use. While the cleaning requirements of your product will vary from device to device, it’s crucial to maintain your diffuser as well as possible. This is due to the fact that the oils can gradually cause damage to the diffuser’s gentle components. Just remember to fully drain the diffuser before each clean and use cotton swabs to really clean hard to reach surfaces.

What essential oils are good for boosting your mood?

There are several essential oils that can help enhance your mood and sense of well-being. These include:

  • Grapefruit oil
  • Lemon oil
  • Frankincense
  • Lavender oil
  • Cinnamon oil
  • Peppermint oil

Each of these also will add a pleasant scent to the air that’s refreshing and light. Some of these will also boost alertness, focus, and will reduce mental fatigue as well.

What essential oils are good for boosting energy?

The world has an addiction to coffee, which isn’t in any way healthy, but most people consider it an essential drink because of its energy-boosting properties. Fortunately, you can avoid drinking coffee altogether and gain extra energy with the use of some important essential oils. These include:

  • Orange oil
  • Lemon oil
  • Lime oil
  • Eucalyptus oil
  • Rosemary oil
  • Thyme oil
  • Basil oil
  • Lemongrass oil

Many of these oils are compatible, so feel free to mix up your own solutions using carrier oils and water if you need to thin out the mixture some. Some of these essential oils have other functions like stress relief and increased cognitive function.

Are there good essential oils for insomnia?

When you have a non-heated essential oil diffuser, you can use essential oils to actually help reduce sleeplessness. Here are few that you can use:

  • Roman chamomile oil
  • Bergamot oil
  • Cedarwood oil
  • Marjoram oil
  • Sandalwood oil
  • Ylang ylang oil
  • Lavender oil

Simply diffuse these into your bedroom at night before you go to sleep, and you’ll have an easier time falling asleep. Some will even improve your mood and make you feel more at ease, which will help you have a more restful sleep.

What are some good extra features to look for?

To sweeten the oil diffuser deal, some manufacturers include additional features that boost the versatility of the oil diffuser. These include:

  • LED lighting – This can be useful when you’re diffusing in a dark room; it provides something of a “night light effect.”
  • Large range mists – Not all diffusers can reach a large area of space, so when you want to really proliferate a large room, purchasing one with a good range is important. Fortunately, there are products on the market with ranges of up to 350 feet.
  • Sleep Timers – Some products will allow you to set the diffuser to stop diffusing after a preset amount of time. This is perfect for those that want to conserve energy/oil during the night.

How much oil should go in a diffuser?

When you’re diffusing oil, you don’t want to overdo it. Typically, 10 to 20 drops into the diffuser will allow you to experience aromatherapy benefits without making the air too heavy with scent. If you’re planning to mix, mileage will vary, but dilute with water if needed.

Out of the types of essential oil diffusers, which is better, vapor, heat, or ultrasonic, which is best?

The most popular form of essential oil diffuser is ultrasonic, and this is for a reason. Ultrasonic products are safe, they diffuse oil quicker, and they tend to last a while on a small amount of oil. These are also the simplest to use; fill with water and add the oil that you want to use.
