11. How to choose
12. How we test

Every home has a signature scent. Four months ago, I took mine into my own hands. Armed with the best essential oil diffusers on the market, I placed one in each room of my home and have been testing them ever since. 

Before I was a product tester, I trained as a Master Perfumer for a luxury perfume and candle company, so I have a lot of experience with home scents. I normally use my picks of the best candles and reed diffusers to scent my space, but I wanted to turn my expertise to essential oil diffusers. They are lower maintenance, tidier, and more consistent. They put out gorgeous scent without you having to lift a finger. You don't need to keep a close eye on them and no there's tedious maintenance like trimming a wick or rotating the reeds. If you're a busy person, essential oil diffusers could be the solution you need to fragrance every room in your home.

Plenty of people make essential oil diffusers, but only a few are worth the investment. I tested lots of models which didn't make this list. Those which did are exceptional: they subtly diffuse scent into every room. Whether you're looking for bold, room-filling fragrances or more delicate diffusers, I've found the only options worth considering.

The quick list

Here are the top notes for these essential oil diffusers. I'll give you more detail about them further down.

❌ You're not good with cleaning: this is tricky to keep looking fresh
❌ You're short on plugs: this occupies a socket
❌ You want color options: this is only in white

The bottom line

🔎 The White Company Motion Sensor: once this is plugged in, it has a day and night mode, diffusing to suit your movements. It's a little limited position-wise though.

The White Company's Ceramic Textured Diffuser is low maintenance. Once you've added 20 drops of essential oil and some water into the diffuser you can leave it for at least six weeks (or until the water level runs low), whilst it diffuses subtle scent into your home. 

Whether you opt for the two, eight, or sixteen hour settings, the diffuser reliably releases delicate fragrance levels into the room. Most people recommend adding 20 drops to your water reservoir. but I found that to be a) too powerful and b) wasteful — if you buy good quality essential oils, you shouldn't need more than seven drops.

This is all dependent on how much essential oil you add to your water level, of course, but most people recommend 20 drops. but I found that to be a) too powerful and b) wasteful — if you buy good quality essential oils, you shouldn't need more than seven drops.

As a smaller, water-based diffuser, I found that this worked best in my bedroom and entryway. The bathroom doesn't have suitable plugs and my kitchen and lounge are a little too big for the diffuser to produce anything notable. A few drops of lavender or eucalyptus oil is all you need for a beautifully scented sleep haven.

The biggest limitation of The White Company's diffuser is that you're limited in where you can place this: it has to always be near a outlet. There's always a battle for outlets in my house, so adding this into the mix became a little frustrating.

It's also worth noting that, whilst the textured ceramic looks beautiful, it's a little trickier to clean. Paired with a water reservoir that needs to be regularly refreshed, and anyone who isn't a thorough cleaner might end up with a slightly grubby looking diffuser.

❌ You want color options: this is very simple

The bottom line

🔎 Bamford Strato: waterless and wireless, this can be moved through your home with ease. It's simple, clean, and impossible to fault.

Bamford's compact and portable atomiser is perfect for modern homes. The clean and simple aesthetics will blend seamlessly into any interior. Not only does it look beautiful, it's crafted from ceramic and recycled plastic, so you know it's doing beautiful things for the planet, too.

The diffuser uses waterless technology and pure essential oils to release a pure, clean scent into your home. I kept mine away from the wall, just in case of any oil marks, but there weren't any. 

I ran mine for ten minutes whenever I felt the room needed a refresh. That was more than enough for my high-ceiling, medium-sized apartment to smell like a spa throughout. Bamford says not to run it for any longer than twenty minutes at a time anyway; it's not needed.

There are three interval settings, each offering distinct strength and diffusion speeds. When you want a stronger scent, you can opt for the highest power option, but I found this a little overwhelming, even with delicate floral and citrus oils. If you're in a low-lit room, the Strato has a soft LED light. It's not bright and garish like other models, perfect for the evenings.

The only issue I have with the Strato is that slotting and lining-up the diffuser oil into the perfect position can take a little bit of work. Thankfully, you won't need to do this often. It's also worth noting that this is more expensive than other models.

❌ Your rooms are all big: this diffuses subtle scent
❌ You're on a budget: this is expensive

The bottom line

🔎 Vitruvi Stone Diffuser: perfect for smaller rooms and subtle scenting, the Vitruvi's matte, ceramic finish is a style piece. However, it's not strong enough for big rooms or pet smells.

This essential oil diffuser is so beautiful that it's easy to forget that it's functional, too. The images online only go a short way towards showing off just how stunning the matte ceramic finish of the Vitruvi stone diffuser is. You can opt for the suede, teracotta, or white colorway. My personal favorite is teracotta, but they all look equally luxurious. Even the packaging is beautiful, so if you need a good option for gifting, this premium product is the one to choose. 

The Vitruvi, unlike lots of diffusers on this list, uses a reservoir and water to scent your space. The smaller reservoir sits in a sealed part of the diffuser, which helps to prevent any leaks or spillage when moving the Vitruvi around. Vitruvi recommends adding 20 drops of essential oil to the reservoir, but do so with caution. I buy high-quality essential oils and only needed to use about 11. If you opt for a lighter, citrus fragrance, you might need more. It's something to experiment with.

There are plenty of other well-considered features, including a four and eight hour timer and LED light. The timer settings are reliable, but subtle. You'll have to add more essential oil if you have pets, for example, because the fragrance isn't diffused very frequently. You also have to control these setting using buttons at the back of the diffuser. These are close to the power cord and a little tricky to reach. Most other expensive models have remote controls, so, if this is a dealbreaker, look at AromaTech and Aroma 360's diffusers.

Another consideration to take into account is that this is a water-based diffuser. By nature, it is higher maintenance, as the reservoir could be a breeding ground for microbes if not properly cleaned. When running water through the diffuser, the Vitruvi makes a dripping noise. Whilst some people found this quite calming, others complained that it was off-putting. It's also worth noting that the matte, textured ceramic exterior collects fluff and can be tricky to get thoroughly clean.
