This calm and soothing Calily™ Tower is tall, thin, and sophisticated to use anywhere as an essential oil diffuser or as a humidifier without using any oils. For a classy look in your environment, this is a great functioning unit to give you the best of both worlds—a diffuser and a humidifier being gift affordable.

This fashionable diffuser is perfect for its lovely fragrance and therapeutic benefits in your home’s bedroom, living room, child’s room, and the bathroom. In professional settings, it is lovely to look at and functions well in a medical office, boutique, your office space, and massage and spa studios.

Using no heat, the oils will maintain their integrity and there will be no compromise for your benefits using the cool method. Add tap or bottled water to the red mark max fill line in the tank and a few drops of your favorite essential oils (not included). No filters are used, so that means low maintenance for you.

The unit is whisper quiet, will not vibrate, has no heat and is healing and cool to touch. The automatic shut off switch provides safety for a good night’s sleep not having to be concerned about it burning out.

Pressing the button once turns the unit on in the continuous mode. Pressing a second time will change it to the intermittent mode. The unit will turn off when you press the button a third time.

LED lights—are therapeutic and will enhance your mood establishing a lovely room ambience. The 6 lights are blue, green, red, pink, purple, and yellow and the colors will rotate or choose to run as a single color. The magical and mesmerizing effects of the oils and lights are delightful and add quiet peaceful moments to your life. In the constant mode, the water supply lasts 3 hours, and in the intermittent mode, the water lasts 6 hours. The unit does not run without lights.

Room size—is up 250 square feet of coverage. Purchase several for each room for a total area fragrance. The water capacity is 90 mL (3 ounces) and the unit will run for hours.

Maintenance—After you use your unit 5 to 6 times, first unplug the unit from the base. Fill the water reservoir with water and one tablespoon of citric acid (sour salt) or two tablespoons of distilled (white) vinegar. Use a cotton swab to clean after letting the mixture soak 5 to 10 minutes. Pour out the solution being careful not to let it get into the air outlet hole on the side. Never submerge the unit in water. Allow the unit to air dry or use a paper towel to dry it inside and out. Mildew and bacteria will grow in your diffuser if you let water sit inside for days and weeks. Always leave it clean and dry when not in use.

As a youngster, I have vivid memories of walking through the large fantastic garden my dad kept for his entire life. It was there I learned about all the plants and the varied, important properties they can offer humanity. A cool morning misty walk down the meandering paths was a child’s delight, and something I still do to this day in my own sprawling gardens. While I have stepped back from the day-to-day managing of Wellness Appliances, I intend to continue contributing articles on subjects that matter to me from time to time. My days are largely filled volunteering at the local co-op, tooling in my vegetable and fragrance gardens (which I attempt to keep as a year-round gardens), writing, and being the leader of the pack to my two dogs Jacko and Lea. Thanks for the years of great readership! - Melissa
