The BTUP cool-mist diffuser holds 100 mL (3.38 ounces) of water to run continuously for 6 long hours in the intermittent mode. Simply fill the water reservoir to the MAX line and no further then add 6 to 8 drops of your favorite essential oils (not included). The manual says to use .015 mL of oil. No one can know milliliters (mL) in drops unless a chemist! Here is the math: 1 drop = 0.0648524 mL. So use your best judgement from 5-10 drops the way you like the aroma best. Three drops is .019, so the .015 is about 1.5 drops—impossible to measure. The rounded edges of the diffuser will fit comfortably in your hands when adding water, oil, and cleaning it.
The best water to use is distilled or purified because there will be no mineral deposits as from regular cold water from the tap. Clean the unit with clear vinegar and water, rinse with water by running it through the unit, and towel dry. You can also use a tad of detergent with cold water, but the bubbles will be hard to rinse away. It is a good idea to put a diffuser on a plate, not a towel, because the moisture can ruin furniture. The unit is whisper-quiet. Do away with pricey candles and chemical sprays and indulge yourself with nature’s pure essential oils that are therapeutic as well as smelling great.
The combination diffuser and humidifier allow you to have it both ways. Add humidity to the air and enjoy the fragrant aromatherapy and humidity or use the diffuser with no oils for moisture in the air for dry skin, colds, and the flu virus. The 5-in-1 unit is a diffuser, a small humidifier, ionizer, air purifier, and night light.
This diffuser is excellent for a baby’s room or for you to get a good night’s sleep. Young people like the lights that mesmerize them to sleep. It is a great addition for a massage or Yoga spa, in the kitchen, the bathroom, chiropractor offices, physical therapists, or your office. Use only 100% pure therapeutic oils (not included). This diffuser will use citrus oils with no problem. You can adjust the mist to the amount you like best. The mist will cover 200- to 300-square feet. However, the fragrance will permeate 1300-square feet for a heady aroma.
The long-life LED lights are 7 changing colors for ambience and a relaxing aromatherapy experience. When you press the ‘light’ button, the colors will change automatically. When you press the button a second time, it will stay on your favorite color. A third pressing will change the colors once more. When you want to turn the unit off for some reason, press, and hold the button for about 2 seconds and it will shut down.
The green light on the front button lets you set the mist from an intermittent 30 seconds on and 30 seconds off to run the diffuser until it runs out of water, then it automatically shuts off. The unit is not waterless; it takes water to make it work. The only diffusers that are waterless are the nebulizer type, so do not be confused by descriptions that can be misleading. The red light button means continuous misting and this will continually mist for 3 hours before shutting off when out of water.
The diffuser is made of polypropylene (PP) plastic and acrylonitrile butadiene styrene (ABS) plastic that gives it its shine and they are BPA-free (bisphenol A) so there are no toxins to be worried about. The cord snaps into the bottom so will never slip out and tip over. The feet are rubberized to hold the unit in place.
The unit is 5.5-inches tall x 3.9-inches wide and weighs about 7 ounces.
Plug the UL listed 5.5-foot cord into a USA 110/120-Volt, 50/60 Hz wall receptacle. Outside the USA, you might need an adapter to plug into a 220/240-Volt outlet. The output is 24-Volts DC at 0.41-amps, and 11-Watts. The ultrasonic frequency is 2.4 MHz.
You will receive a User’s Manual, the BTUP diffuser, 1 power adaptor, and a water-measuring cup. Warranty information is unavailable and the unit is made in China.
