We spent 28 hours on research, videography, and editing, to review the top options for this wiki. Many people combat bad smells and stress with the scents of 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 easily control them with an app, or through a digital assistant, like Alexa. When users buy our independently chosen editorial picks, we may earn commissions to support our work. Skip to the best smart diffuser on Amazon.
