Important Safety Instructions


  1. The appliance should ALWAYS be placed on a firm, flat, waterproof surface at least four feet (1.2 m) away from the bedside, 12 inches (30 cm) from the wall, and out of reach of patients, children, and pets. Be sure the appliance is in a stable position and the power cord is away from heated surfaces and out of the way to prevent the humidifier from being a tripping hazard.
  2. The appliance should not be left unattended in a closed room. Leave the room door partly open. DO NOT aim Mist Outlet directly at walls, furniture, and bedding.

  4. The appliance has a polarized plug (one blade is wider than the other) as a safety feature. This plug will fit into a polarized outlet only one way. If the plug does not fit fully into the outlet, reverse the plug.
    If it still does not fit, contact a qualified electrician. DO NOT attempt to defeat this safety feature.
  5. To avoid fire or electric shock hazards, plug the appliance directly into a 120V AC electrical outlet. To avoid the risk of fire, electric shock, or personal injury, DO NOT use an extension cord or power strip.

Getting to Know Your Vicks VUL525/545 Series Humidifiers

How it Works
Water is released from the Water Tank into the Reservoir. A Nebulizer vibrates at an ultrasonic frequency, breaking the water into a fine mist. The mist is quietly propelled by a fan up a vertical Mist Chamber to the Mist Outlet where the cool, visible mist enters the room. This humidifier will shut off when the water level is low or when the Tank is removed from the Base.

Setting Up Your Humidifier

Unpack the Humidifier
Keep this Owner’s Manual for referenceVICKS Filter Free Ultrasonic Cool Mist Humidifier fig (3)

  • Remove packaging materials. Remove the twist tie from the power cord and extend the power cord to full length.
  • Place on a firm, level, water-resistant surface a minimum of 12” (30cm) from any walls. The mist should be directed away from any walls, bedding, and furniture.

Hard Water and White Dust

  • High mineral content in your water, also known as hard water, may cause a white mineral residue to accumulate on surfaces in the room near the humidifier. This mineral residue is commonly referred to as white dust. The higher the mineral content (hardness) of your water, the greater the potential that an ultrasonic humidifier may produce white dust.
  • White dust is not a result of a defect or flaw in the humidifier. It is a result of the number of minerals suspended in the water you are using.
  • To reduce white dust, use distilled water or a Protec PDC51V2 Demineralization Cartridge available through Consumer Relations; see back of this manual.


NOTE: Tank should be carried using two hands. One hand uses the carrying handle located on a tank top and the other hand supports the base of the tank.
Helen of Troy will not accept responsibility for property damage caused by water spillage.

Daily Maintenance

Weekly Cleaning

To properly clean your humidifier we recommend the separate processes of Scale Removal and Disinfecting shown below. These two processes must be performed separately.

Instructions for Scale RemovalVICKS Filter Free Ultrasonic Cool Mist Humidifier fig (8)
