To the uninformed, essential oil diffusers may come off as nothing more than glorified air fresheners, but there are a few core differences that separate these devices from their aerosol-powered peers. While air fresheners tend to douse the air with irritating chemicals, diffusers revitalize your living space with natural oils and are even known to help improve sleep, reduce stress, and prevent illness. The Smart Alexa-Compatible Ultrasonic Aromatherapy Diffuser lets you bring these benefits to your living space on command. It's available in the Boing Boing store for $41. Engineered with advanced vaporizing plates, this smart diffuser is designed to evenly distribute oils in your home. It features a 400ml water tank and is capable of producing up to 12 hours of continuous mist. Using your phone, you can control features like LED color, mist intensity, timer settings, and scheduling, or if you're looking for a more hands-off approach, you can integrate the device with Amazon Alexa and control it with your voice. The Smart Alexa-Compatible Ultrasonic Aromatherapy Diffuser is on sale in the Boing Boing store for $41.
