You know when you walk into a spa and immediately feel at peace? It's not just the knowledge that you're about to receive a blissful two-hour massage or the idea that you can disconnect for an afternoon—it's the soothing scent that most spas are enveloped in: eucalyptus, lavender, basil, bergamot. And while it's not always easy (or affordable) to make it to the spa on a regular basis, it's possible to re-create the same relaxing vibes at home. All you need is a scent diffuser.

Whether it uses ultrasonic or nebulizer technology or the simple power of a small candle, scent diffusers can envelop your entire home in the smell of essential oils that can help you relax, get energized, focus, or sleep.
