Editor's Notes

November 07, 2019:

The diffusers in this list do more than just make your home or office smell good. They also serve as mini humidifiers and can make dry spaces feel much more comfortable, and some of the devices we've picked out have color-changing LED lights that provide a little bit of ambiance, too. The models featured here have multiple timer settings that make it possible to set it and forget it, as they say. Additionally, they're all compatible with every type of essential oil out there, so you don't have to worry about having to purchase brand-name cartridges, wax melts, and the like just to get your diffuser up and running. All you have to do is add water and a few drops of your favorite oil.

The Zeigga Lab Pink and Homesick Ultrasonic are the list's newest additions, chosen for their elegant designs, solid performance records, and overall popularity among users. The VicTsing Essential has been removed and replaced with an updated version, the Homasy Aroma.

5 Questions To Ask Yourself Before Choosing An Oil Diffuser

Here are important questions you need to ask yourself in order to choose your perfect oil diffuser:

Although there's a good price range among the diffusers on our list, at the top end they retail for up to $130 at full price. We know that if you're thinking of parting with that amount of money, you want to be sure that you're buying something completely right for you.

Here are important questions you need to ask yourself in order to choose your perfect oil diffuser:

1. Do you want aromatherapy - or just the aroma? As discussed in the first video we've shared above, to make the most of the therapeutic benefits of your essential oil - rather than just the refreshing scent - you probably want to use either a nebulizing or an ultrasonic diffuser. All of the diffusers we've rated on this site fall into one of those two categories, so this is a great place to start!

2. Do you also want to use your diffuser as a humidifier? Because ultrasonic diffusers use water to disperse the essential oils, they also have the added benefit of reducing dryness in the air. Particularly during colder weather, this can have benefits for your skin in particular, but can also help to reduce snoring and possibly even nose bleeds.

3. Where are you going to use your diffuser? This is important for three reasons: one is the size of the space, because nebulizing diffusers like our top-rated choice, the Aromis Orbis Nox Merus, are much better than other varieties at dispersing essential oil throughout larger spaces.

Secondly, if your diffuser is for use in your bedroom, you're going to want one that operates quietly - see our article below for more advice on using an oil diffuser to create a relaxing atmosphere in your bedroom.

The third reason is more subjective: take some time to consider which room in your home is going to be the setting for your oil diffuser, and then you can pick a diffuser that looks right with your furnishings and color scheme.

4. How are you going to ensure the diffuser is used safely? Look for a diffuser that comes with a timer feature (for nebulizing diffusers), or an automatic shut-off function when the water inside runs out (for ultrasonic diffusers). Most if not all of the diffusers we've rated here come with one of these features.

5. What about optional extras? A lot of the diffusers we've rated here come with lighting effects - these can be especially nice if your diffuser is for a child, or if you're using it to create a relaxing spa effect. Some users, however, find these lights distracting, especially if the diffuser is for use at bedtime. Check the descriptions before you buy to make sure that if there is a light with the diffuser, it can be switched off if and when you prefer not to use it.

If, like many consumers, you're keen to reduce your energy usage for financial and/or environmental reasons, then check out our list for diffusers that promise to use an energy-efficient mechanism.

Get A Perfect Night's Sleep With Help From Your Oil Diffuser

The health benefits of aromatherapy are the subject of much debate. But here are a couple of things we can all agree on:

  1. Getting enough sleep is hella important. If you've not watched Arianna Huffington's TED talk about the benefits of sleep, get on it.

The health benefits of aromatherapy are the subject of much debate.

  1. You can help ensure you get a better night's sleep by optimising your bedroom environment and your bedtime routine - check out steps 2 and 3 in this article from the Division of Sleep Medicine at Harvard Medical School.

So let's get started with that bedtime routine. When you switch off all your devices before bed, you could get into the habit of switching on your diffuser instead. Load it up with an essential oil recommended to aid sleep, such as lavender.

Next you need to think about your sleep environment. Ideally, your bedroom should be as dark as possible, but if you find a little light relaxing - maybe you'd like to read awhile before you go to sleep - pick a diffuser that lights up in soft colors.

Finally, your bedroom needs to be a quiet place. The mechanism in some ultrasonic diffusers can be a little noisy, so be sure to pick a quiet model - check out our list above for diffusers that promise to let you sleep in peace.

Six Thousand Years Of Essential Oils: A Brief History

Humans have been using plants for their healing properties for almost as long as we've existed, and we can trace the use of essential oils back almost 6000 years. Here are just a few highlights from that long and brilliant career:

The Ancient World - Ancient civilizations including the Egyptians were using essential oils as early as 4500 B.C.E.

In China, the legendary Yellow Emperor Huangdi wrote The Yellow Emperor’s Book of Internal Medicine, which incorporates the use of aromatic oils, between 2697-2597 B.C.E.

Here are just a few highlights from that long and brilliant career:

Essential oils are also an essential (sorry...to be honest you're lucky that's the first time we've used that pun on this site) part of ayurvedic medicine, an Indian tradition with a 3000-year history.

Hippocrates, the father of modern medicine, wrote about the benefits of many plants still used today in essential oil form, such as thyme and peppermint.

Modern Times - It was in the 20th century that the use of essential oils came to be referred to as 'aromatherapy': the word first appeared in print in 1937, in a French book called Aromathérapie: Les Huiles Essentielles, Hormones Végétales, by a chemist called René-Maurice Gattefossé.

Gattefossé had begun to analyze the chemical properties of essential oils and their use during the First World War - treating burns, skin infections, gangrene and even wounds - after his own first-hand experience, figuratively: an explosion in his laboratory burned his hand and he claimed to have treated it successfully using lavender oil.

Another French man - a surgeon called Jean Valnet - continued the medicinal use of essential oils by employing them as antiseptics during the Second World War.

By the 1950s essential oils had become established tools of the trade for many professionals, including massage therapists, beauticians and some health care providers, and this continues to this day.
