15 Best Electric Diffusers 2023 for Spa Vibes at Home

By Sophie Cockett and Lucy Smith

Electric diffusers are the easiest way to create a spa-like experience in the comfort of your home, and make your space smell lovely. Paramount, in a world where our bedrooms double-up as places of work.

Sure, scented candles, room sprays and reed diffusers have their benefits, but the best electric diffusers – or nebulising diffusers, as they're often otherwise also referred to – have the power to fill your home with calming, restorative or energising scents more quickly than their counterparts, while eradicating any risk of spillage. Or your curtains going up in flames. How? They emit a continuous stream of mist containing drops of essential oil at a high air pressure into your room, filling a space of any size with a beautiful scent and allowing you to take advantage of the benefits of aromatherapy.

They're really affordable to run, can be left unattended thanks to automated time settings, and many of them double up as other appliances like night lights, speakers or stylish pieces of home decor. Life changing? You bet. Ahead, everything you could possibly need to know.

We surveyed the GLAMOUR office to find out what editors and wellness experts look for in the best electric diffuser. Then, we tested every model over a period of at least one month in our homes, assessing them on factors like fragrance intensity, ease of use, automatic shut-off, water capacity and design. Our edit features only the electric diffusers we really loved – and we've given each a star rating to make your choice even easier.

Essential oil diffusers use ultrasonic pulses to blend drops of essential oil with water before circulating a fragranced, cool mist around your room. Electric diffusers have the power to fill your space with subtly-scented purified air that helps you feel relaxed or perhaps more focused – depending on which essential oil you choose (more on that later). But that's not all. Investing in an essential oil diffuser also allows you to take advantage of the benefits of aromatherapy.

According to Robert Tisserand, an Essential Oil Educator and Aromatherapy Expert from California, "Clinical studies have shown that aromatherapy by inhalation can have real benefits for people with, for example, anxiety, [problems with] mental focus, depressive symptoms, and menstrual pain."

Further research has supported this, showing that essential oils can interact with the brain and nervous system to positively impact your health and mood. That said, Jo Kellet – essential oils expert at Tisserand – added that essential oils should not be applied directly to the skin, even with their numerous benefits. Indeed, Jo explained, "Essential oils need to be diluted before being applied to the skin in either a base oil, lotion, or cream, for example. They are concentrated essences that can, if used neat, cause a severe skin reaction, or over time build up a sensitivity to that essential oil." Enter: the essential oil aroma diffuser.

When essential oils are concentrated in an essential oil diffuser – and subsequently inhaled – they can easily stimulate the olfactory system in the brain. Thus, running an ultrasonic diffuser can effectively reduce feelings of anxiety and stress – and help you nod off to sleep.

Yes. Essential oil diffusers are safe, and their risk of harm is minimal. In fact, inhalation is arguably the safest means of administering essential oils like eucalyptus or tea tree. To be extra safe, when shopping for your essential oil blend, be sure that it specifically says on the bottle or website that it's considered safe for internal consumption. This means the essential oil is safe to diffuse indoors and is high-quality.

Jo explains one of the ways she ensures her oils are still safe for use if you've owned them for a long time: "Essential oils may change odour or colour and more importantly may cause skin sensitivity if used beyond their best before date. We, therefore, recommend that you use your essential oils within one year of opening them to minimise this risk." She continues: "A good way to keep a check on this is to place a sticker on your bottle with the date of opening." Take note.

Not particularly, and they're not particularly expensive to run. If you're worried, you go for something cordless or powered via USB. You just need a few drops of essential oil and some water, and you're good to go.

One of the best things about investing in an essential oil diffuser is that you can switch up the oils you’re using depending on your needs at that time. Lavender is good to help you relax before bed (we recommend the Tisserand Lavender Essential Oil), while rosemary will help you stay focused when you're working from home. Cedarwood, lemon, bergamot, vanilla, lemongrass, orange and valerian are good for stress and anxiety, while peppermint is good for a mood boost.

Electronic Diffuser, £70, The White Company

Pros: Forever the most popular electric diffuser among GLAMOUR readers and editors alike, The White Company's iteration not only looks super sleek and stylish on your bedside table but delivers the perfect amount of scent in minutes. We loved that there were different time settings to choose from (180 minutes, 120 minutes and 60 minutes) and that the diffuser automatically shut off at the end of the time set. It's made from ceramic which makes it look more expensive than it actually is, and The White Company's fragrance oils selection is – as expected – incredible.

Cons: Some reviews pointed out that the ‘wood' base is actually plastic, which is worth noting.

Dimensions: W93mm x H180mm.Maximum mist time: 180 minutes.Water capacity: 100ml.Cordless? No.

GLAMOUR star rating: 5/5 ⭐️⭐️⭐️⭐️⭐️

Textured Ceramic Electronic Diffuser, £80, The White Company

Pros: If you're a fan of minimalistic interiors and want something that'll blend seamlessly with your contemporary and modern home, this is it. A gorgeous choice for bedrooms, it boasts a lovely herringbone design and a white base. It's functional, too: it has three timer settings so you can choose how long the diffuser releases scent (two hours, eight or sixteen hours). Plus, the diffuser will automatically shut off at the end of each time set or when the water level is low. It comes with a multinational for travelling buyers, a generous 300ml water capacity (most competitors only have 100ml capacities), and numerous reviews claim it successfully fills the room with your chosen home fragrance quickly.

Cons: It does not include a mood light.

Dimensions: L16cm x H11cm.Maximum mist time: 16 hours.Water capacity: 300ml.Cordless? No.

Pros: Larger and more powerful than both the original, best-selling Wellbeing Pod and their portable Pod Mini, the NEOM Wellbeing Pod Luxe is designed to deliver the perfect amount of scent to an open-plan home, large office space or occasion room in minutes. It reaches up to 100 square meters. It's very easy to clean, and the design features a white ceramic diffuser cover set on an upcycled wood grain base. There's a touch display and remote control so that you can control the mist modes and colour-changing light options without standing up. You can also get it with next-day delivery at retailers like John Lewis and LookFantastic.

Cons: Water to pure essential oil ratio requires quite a lot of the latter to fill larger rooms.

Velma Floral Pink Essential Oil Electric Aroma Diffuser, £45, Oliver Bonas

Pros: This geometric-design diffuser boasts all the time-setting, light-changing bells and whistles, but this time, it's one for the minimalist girlies with its neutral cream and stone colour-way. You can set it to work for 30 minutes, an hour, two hours or three, depending on what suits your needs, and it has colour light settings – including white, blue, green and yellow – to achieve your desired ambience.

Portable Rechargeable Electronic Diffuser, £55, The White Company

Pros: The White Company's latest electric diffuser launch comes in the form of this small, smart and compact portable electronic diffuser, which we love for its abilities to be used indoors ~and~ outdoors. It's compatible with any of TWC's fragrance oils, works within seconds and makes a great addition to a WFH desk. It has four settings which we found to be enough for a diffuser of this size, and the ultra-sonic technology creates a strong and finely atomised mist.

Cons: You need to remember to manually turn off the diffuser when the tank is empty to preserve battery life.

Dimensions: H17cm x D7cm.Maximum mist time: Three hours continuously, or eight hours interval time five minutes on/off.Water capacity: 45ml.Cordless? Yes.

GLAMOUR star rating: 5/5 ⭐️⭐️⭐️⭐️

Pros: From John Lewis' affordable ANYDAY range (available in-store and online at johnlewis.com) comes the best essential oil diffuser for practicality – thanks to the plethora of features which make it so easy to use. You can scent your room at the touch of a button with the John Lewis ultrasonic diffuser – it starts misting immediately and dispenses fragrance immediately, too – and it has an auto shut-off function for peace of mind which activates when the water tank is empty. There is a range of LED light functions depending on your mood, and the mist comes out in a constant stream for 0.5 hours, one hour, two hours or three hours – as opposed to 30-second on/off intervals. Consider your home a spa.

Cons: Synthetic base and colours don't fill the entirety of the ceramic lid.

GLAMOUR star rating: 4/5 ⭐️⭐️⭐️⭐️

NEOM Wellbeing Pod, £95, NEOM Organics

Pros: The NEOM essential oil diffuser not only looks really sleek, but it delivers the perfect amount of scent quickly – making it better than some of the real luxury reed diffusers on the market. Plus, NEOM's natural essential oil blends are among our favourites. You actually only need to fill it up to the maximum water level line and add five to 10 drops of your chosen NEOM Wellbeing Essential Oil Blend to get going (they're sold separately). With the simple touch of a button, this oil diffuser will instantly release a heatless, fine mist that noticeably improves your mood.

MADE BY ZEN Arran Aroma Mist Diffuser, £65, Amazon

Pros: This cordless essential oil diffuser is crafted from hand-cut, sustainably sourced bamboo. It boasts a gorgeously-glowing light (either static or colour-changing) to help you achieve the dreamiest ambience, be it to do your skincare or simply curl up with a good book.

Cons: Lighting isn't bright enough to read with and only runs for five hours (lower than some others on the market). Think of this device more as an ongoing pillow mist to fall asleep to.

Plus, there is no need to clean in between.

Founder and Creative Director Nicola Elliott: "Mini by name, mini by nature. Made for those small spaces where you need a well-being boost – like a small work-from-home setup and home office, modest bathrooms (or little lavatory), the car, or a little bedroom."

There's an auto-stop feature, a warm illuminating LED light to set a cosy ambience, and it runs for up to six hours.

Cons: It's not quite as powerful as some of the other more expensive diffusers in this edit.

GLAMOUR star rating: 5/5 ⭐️⭐️⭐️⭐️

Aromatherapy Associates The Atomiser Pure Essential Oil Ceramic Diffuser, £120, LookFantastic

Pros: Inspired by spa atomising technology, this ultrasonic diffuser uses powerful air compression to disperse a micro-fine mist direct from the bottles of 100% natural, pure essential oil blends – without any cold water. You get what you pay for: unlike other electronic diffusers in this edit, there is no water tank, which means the integrity of the pure oils is preserved. And the fragrance is more potent as an air freshener for living rooms and large spaces. We also love that it has multiple runtime options, including 'Boost mode', which speeds up the process of making your home smell oh-so-good.

Cons: Some reviews say the slight noise detracts from the relaxation.

DIPTYQUE Un Air de Diptyque Electric Diffuser, £240, Net-A-Porter

Pros: The most expensive essential oil diffuser in this edit comes from luxury fragrance house Diptyque, famed for their insane scented candles – namely Baies and Roses. Crafted from ceramic for an expensive-looking finish, it's adorned with gold lettering (making it one of the most beautiful additions to your living space) and slowly emits perfume through the air. It's easy to set up, too – you simply need to slot one of the brand's perfume capsules in the back, and you're ready to go.

Cons: It's pretty expensive and does a rather similar job to more affordable diffusers in this edit. It's only compatible with Diptyque diffuser capsules: Baies, Figuier and Feu de Bois Diffuser Capsule.
