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 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 HumidifierKeep this Owner’s Manual for reference

  • Remove packaging materials. Remove twist-tie from the power cord and extend power cord to full length.
  • Place on a firm, level, water-resistant surface a minimum of 12” (30cm) from any walls. Must 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 amount 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 using the carrying handle located on tank top and the other hand supporting the base of the tank.Helen of Troy will not accept responsibility for property damage caused by water spillage.VUL525 holds 1/2 gallon (1.9L) of water and VUL545 holds 1 gallon (3.8L) of water (tank and reservoir combined).

Make sure water does not enter the fan opening (vented opening on right side of Reservoir) or Power Knob.CAUTION: DO NOT SUBMERGE BASE IN WATER. DOING SO WILL DAMAGE THE HUMIDIFIER AND VOID THE WARRANTY.
