HOW TO USE

Before use, check the humidifier for leaks and visible damage that may have occurred during shipping. DO NOT USE if there is evidence of damage.

FILLING WATER TANK

  1. Unplug the humidifier and place it on a level surface.
    Note: Spills can occur during cleaning, moving, or refilling the water tank, so be careful to avoid spills.
  2.  Remove the water tank by grasping the water tank handle and pulling it toward you.
  3. Turn the water tank upside down and remove the cap (turn the cap counterclockwise to open).
  4. Fill the water tank with cool tap water and replace the cap (turn clockwise to close).
    TIP: If you have hard water or water with excessive minerals, we recommend using distilled water to help reduce white dust and mineral buildup.
  5. Lower the water tank into the base, positioning the water tank cap outlet valve over the raised post in the base. Once in the nested position, the outlet valve inside the cap opens, releasing water into the base.
    Note: Any additives, such as aroma fragrances should not be used in the water tank or base. These additives can cause cracks in the plastic of the humidifier and may affect performance. Any use of such additives voids the manufacturer’s warranty.

Easily operate and control mist settings and nightlight function with the illuminated touch power button. Touch POWER ICON to cycle through settings as follows:

  • MODE 1 – Powers humidifier on and high mist setting without a nightlight
  • MODE 2 – High mist setting with nightlight
  • MODE 3 – Low mist setting without nightlight
  • MODE 4 – Low mist setting with nightlight
  • MODE 5 – Powers humidifier off.
    The illuminated LED around the power icon will illuminate when the unit is powered on. When selected the LED nightlight will illuminate in the base and is located near the mist tube.

HIGH MIST SETTING

Operation for fast humidification of small to medium-sized rooms. High-speed operation will evaporate 1.2 gallons of water (+/- 10%) in 24 hours of continuous operation. (This assumes room conditions of 70º F and 30% relative humidity.)

LOW MIST SETTING

Operation for quiet, nighttime use or smaller rooms. On Low operation, your humidifier may run without refilling for extended periods.
TIP: Lower the mist setting or turn off the humidifier if moisture forms on walls or windows.

LOW WATER INDICATOR & AUTO SHUTOFF

When the humidifier detects a low water level the LED around the power icon will briefly flash red to indicate the water tank needs refilled before automatically powering off. Refill the tank and power the humidifier back on to resume operation.

CLEANING

Proper cleaning is essential to the air quality and performance of your humidifier. The frequency in which your humidifier will need to be cleaned will vary depending on use, water hardness, and outside environmental factors. It is recommended, assuming average use, to thoroughly clean weekly or when
algae, mineral deposits or other particles begin to form. If the humidifier is turned off with water in the base and not turned back on for 8 hours or longer, or if the humidifier is not cleaned as recommended, you may experience some growth of algae or bacteria. These microorganisms may become airborne.

NOTE: Do not use gasoline, thinners, solvents, or other chemicals for cleaning.

CLEANING INSTRUCTIONS

  1. Turn the humidifier off, unplug it from the wall, and disconnect the adapter from the base.
  2. Remove the water tank and empty the tank and any remaining water in the base.
  3. Rinse the mist tube located inside the water tank with clean tap water. Remove the mist nozzle prior to cleaning the mist tube.
  4. On occasion, the water tank may need to be gently wiped down or cleaned to remove the buildup of impurities. Clean with a mild detergent and rinse with clean tap water.
  5. Clean the base using a soft cloth or the cleaning brush (included) with a mild
    detergent and rinse with clean tap water. Do not submerge the base in water.
  6. Locate the ultrasonic disk on the inside center of the base. Use the cleaning brush to gently clean the disk. Do not scrub or scrape the ultrasonic disk. Do not clean the ultrasonic disk with any other tool than the provided cleaning brush.
  7. Wipe the outer surface of the unit with a soft, damp cloth if needed.

STORAGE

STORAGE

During the off-season or after extended periods of non-use, you may choose to store your humidifier. To ensure the long life of the product, it is recommended to store your humidifier by following these instructions:
TIP: Cleaning is recommended before storage.

  1. Unplug the power cord and bundle it loosely.
  2. Let the humidifier dry completely before storing. Do not store water inside water tank or base.
  3. Cover, or place back in retail carton if available. This will prevent the humidifier from accumulating dust over time.
  4. Store the humidifier in a cool and dry location.

Sharper Image UHT1-SI Ultrasonic Cool Mist Humidifier-FAQs

Why won’t my Sharper Image ultrasonic humidifier turn on?

If your humidifier doesn’t turn on, try emptying the water, unplugging the unit, and letting it reset overnight. If it still doesn’t work, there may be internal damage, and the humidifier might need to be replaced.

How do I fill my Sharper Image humidifier?

Always use cool, fresh water when refilling. Turn the water tank upside down, unscrew the cap, and fill it with water before securing the cap back in place.

How do I know if my ultrasonic humidifier is working?

Set the humidistat to a high level and place a piece of paper near the mist outlet. If the paper stays dry after a few hours, the humidifier is not functioning properly.

Why does my humidifier keep shutting off?

If the humidifier is set to automatic mode, it might detect high humidity too quickly, causing it to shut off. Try adjusting the humidity settings manually.

How does an ultrasonic humidifier work?

Ultrasonic humidifiers use high-frequency vibrations to break water into tiny droplets, creating a cool mist that adds moisture to the air without using heat.

What is the ideal humidity setting for my humidifier?

Experts recommend keeping indoor humidity levels between 40-60% year-round and around 35% during dry winter months to maintain comfort and air quality.

Do ultrasonic humidifiers get hot?

No, ultrasonic humidifiers do not use heat and remain cool to the touch, making them a safe option for homes with children and pets.

Can I sleep with a humidifier on?

Yes! Using a humidifier while sleeping can improve air quality, prevent dry skin, support respiratory health, and reduce flu risks by maintaining proper humidity levels.

How does an ultrasonic mist maker work?

An ultrasonic mist maker uses ceramic discs that vibrate at high frequencies to create fine water droplets, producing a cool mist without noise or heat.
