The soft, soothing scent of essential oils can relax you can create a better environment for your home. Things have come a long way since the days of a few simple rattan sticks poking out of a bottle of essential oils. One of the best ways to benefit from these soothing scents is with a modern smart electric diffuser. Not only do they give you far more control over how and when you choose to use them, but they’re also just better overall.
Our recommendations: The best smart diffusers so far in 2022
Best overall: Maxcio Alexa Wi-Fi Diffuser
Striking a balance can be difficult, but this Wi-Fi-enabled oil diffuser somehow manages to be excellent at everything it needs to be. Combining smart features, a great design, gorgeous looks and a nice price, it’s by far the best smart enabled oil diffuser we’ve reviewed.
With a large 400ml water capacity and two operating modes (30 and 80ml,) it can run for up to 12 hours, more than enough for a night, with a waterless automatic shut off for safety and to prolong the diffuser’s lifespan.
7 LED lights complement the classic looks, but despite looking like something you’d see in a 500-year-old Buddhist temple, it’s packed with smart controls, both via the app, and using voice commands via Alexa or Google Nest.
Verdict: Overall, this has everything we look for when reviewing electric diffusers. It has a superb natural design, is extremely quiet and has well-implmented smart features and app control. This is a great smart diffuser for the price.
Best as a nightlight: Asakuki Smart Diffuser
Attractive and distinctive, this combines humidifier and diffuser from Asakuki is a fantastic general option, especially if you want to use it as a nightlight for your baby. And it’s one of the cheapest smart misters you can buy in 2022.
This is because, despite being a reasonably large, cube design (which is great, by the way, as it gives it a huge 700ml internal reservoir, which lasts up to 16 hours of use!) the light it gives off is soft, natural and warm, especially when you set it to the dedicated nightlight mode.
It can be controlled using the simple buttons on the bottom of the stand, but you’re going to want to install the Tuya app, which gives you full control over timer, mist density and scheduling. Alternatively, you can just ask your home hub to switch it on or off, if you have one.
Verdict: Honestly, the app is the only real downside to this smart diffuser, as there are a few options (scheduling, especially) that you can only do through the app. If it had better on-device controls, this would probably have stolen the top slot. On the flip side, it’s a solid diffuser with a bargain price tag.
Longest lifespan: Switchbot Ultrasonic Humidifier
Switchbot is known for its impressive tech, creating everything from smart plugs to robot vacuums, all of it good, and their ultrasonic humidifier follows that trend.
While the design is a little more utilitarian than most of the rest of the list, meaning you’ll admire this for its function over its looks, the features list is very impressive.
Firstly, the water tank is absolutely massive, holding up to 3.5l. That’s more than ten times most of the diffusers on this list, and means this can last a ridiculous 48 hours without having to be refilled. It’s quiet, at less than 36dB (about the level of background fan noise.) The top-fill design is also really simple to use, which is appreciated.
Mist is dispersed with a powerful nozzle that rotates the full 360 degrees, can be set to 1 to 100% humidity, and fires a full 24 inches from the device.
Verdict: As it’s a Switchbot product, it also runs on the Switchbot ecosystem, so you know the app is good. You can connect to the Switchbot hub, change any settings, activate the automatic mode, auto shut off, the works. It’s also fully covered by a strong 1-year warranty.
Best for baby: Etersky Smart Diffuser
One major reason a lot of people turn to diffusers is to help their newborn sleep by keeping the room cool, at the right humidity, with all the benefits of essential oils.
Coming in at a low 30dB (the sound of someone whispering) and with a 10-hour function, this WiFi aroma diffuser is the perfect companion for your child’s rest. BPA free, it’s completely infant safe and can be set to timers if you just want it running all night.
If you want a little more control, the Smart Life app lets you select specific features, or you can connect it to your home hub and switch it on or off via Alexa, meaning you can even control this from the comfort of your own bedroom, first thing in the morning.
Verdict: A good price point, eye-catching design and safe to use around infants. This is a fab smart diffuser that’s easy to use and extremely robust.
Most portable: Neom Portable USB Diffuser Pod
While it’s technically not a ‘smart’ diffuser, we loved this little trinket model so much, it had to make the list.
Compared to everything else we’ve reviewed here, this is a completely different animal. It’s tiny (hand-sized) and incredibly portable. You load it up, and at any time, you can release a burst of essential oil at the touch of a button.
Using cold fusion technology, any oils used are completely pure and untainted, and, charged via USB, it can hold upwards of 50 hours of battery. Perfect for offices, your bedroom, or use in the car, this is a fantastic backup to every other diffuser on the list.
