Brighten up your home or office with this dual-function humidifier and diffuser. Use your own essential oils or one of our excellent body oils and perfume-type oils to create a lasting scent and freshness anywhere you choose. This diffuser simulates a beautiful orange flame like a personal fireplace. The light is soft enough for a nightlight, but you can also switch the light off when it's time to sleep. The diffuser can hold 180 mL of water and run for 8 to 10 hours on one fill. Only a few drops of your preferred oil are required. The humidifier works exceptionally well in all temperatures and is portable, making it easy to take with you on trips or in different rooms. The diffuser is also programmed with a safety auto shut-off feature which prevents it from overheating once the water runs out. So you can come back to an incredible fresh smell with no worries.
