This wiki has been updated 12 times since it was first published in December of 2017. Many people combat both bad smells and stress with essential oils. But if you're putting your peppermint and lavender into a traditional device, you may find yourself constantly getting up to adjust the settings. These smart diffusers make that inconvenience a thing of the past. They are WiFi-enabled, so you can control them with an app or via a digital assistant, like Alexa. When users buy our independently chosen editorial choices, we may earn commissions to help fund the Wiki. Skip to the best smart diffuser on Amazon.

Editor's Notes

July 10, 2019:

We understand that any time you add something to your home, you want it to mesh well with your existing decor. For that reason, we have included many different types of designs on this list. If you love wood grain, then you'll want to consider the Sierra Modern Home 400ml and InnoGear Cool Mist Wifi. Not only do both of these models look great, but they also function reliably and neither costs an arm and a leg. If you prefer just a touch of wood grain to accent the style of your diffuser, but want it to have a more modern appearance overall, check out the Asakuki DF010 and Queence Galaxy Globe, the latter of which has a very striking visual aesthetic. Those who prefer a clean, white design will appreciate the Vococlinic FlowerBud, Emoi H0027, Yeshow Essential, and Geeni Spirit.

Most diffusers use liquid essential oils that you need to mix with water yourself for their fragrance, but the Moodo Home Fragrance and Aera Microdroplet are very different. These models use replaceable scent capsules that make for very convenient operation. You won't have to worry about filling them with water and can simply run them as often as you like until the scent capsule runs dry. The major downside to these two models is that the capsules are proprietary and buying new ones can get rather costly.

He has been a professional chef, a dog trainer, and a travel correspondent for a well-known Southeast Asian guidebook. He also holds a business degree and has spent more time than he cares to admit in boring office jobs.

His expertise, honed over years of experience, is in the areas of computers, electronics, travel gear, pet products, and kitchen, office and automotive equipment.
