Important Instructions

When using electrical appliances, basic precautions should always be followed to reduce the risk of fire, electric shock, and injury to persons, including the following:

  • Read all instructions before using the appliance.
  • IMPORTANT – This appliance has a polarized plug (one blade is wider than the other). To reduce the risk of electric shock, this plug is intended to fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician. Do not attempt to defeat this safety feature.
  • To avoid fire or shock hazards, plug the appliance directly into a 120V AC electrical outlet.
  • Keep the cord out of heavy traffic areas. To avoid fire hazards, NEVER put the cord under rugs, near heat registers, radiators, stoves, or heaters.
  • To protect against electrical hazards, DO NOT immerse in water or other liquids. Do not use near water.
  • Extreme caution is necessary when any appliance is used by or near children or people with disabilities and whenever the appliance is left operating unattended.
  • Always unplug the air purifier before moving it, opening the grill, changing filters, cleaning, or whenever the air purifier is not in use. Be sure to pull by the plug and not the cord.
  • NEVER drop or insert any object into any openings.
  • DO NOT run the cord under the carpeting.
  • DO NOT cover the cord with throw rugs, runners, or similar coverings.
  • DO NOT route the cord under furniture or appliances. Arrange the cord away from the traffic area and where it will not be tripped over.
  • DO NOT operate any appliance with a damaged cord or plug, if the motor fan fails to rotate, after the appliance malfunctions, or if it has been dropped or damaged in any manner. Call Customer Service at 1.866.603.5900 for assistance.
  • Use appliances only for intended household use as described in this manual. Any other use not recommended by the manufacturer may cause fire, electric shock, or injury to persons.
  • DO NOT use outdoors.
  • DO NOT place anything on top of the unit.
  • NEVER block the air openings, grills/outlets, or place on a soft surface such as a bed or sofa, as this could cause the unit to tip over, blocking the air intake or outtake opening.
  • DO NOT attempt to repair or adjust any electrical or mechanical functions on this unit. Doing so will void your warranty. The inside of the unit contains no user-serviceable parts. All servicing should be performed by qualified personnel only.
  • WARNING: To reduce the risk of fire or electric shock, do not use this fan with any solid-state speed control device.
  • WARNING: Skin or eye damage may result from directly viewing the light produced by the lamp in this apparatus. Always disconnect the power before replacing the lamp or servicing it. Replace Lamp With Lamp Manufactured by Guardian Technologies.
  • Always unplug the unit before cleaning or servicing it in any way.
  • CAUTION: Do NOT use gasoline, benzene, thinner, harsh cleaners, etc. on and/or in the unit while cleaning as they will damage the product. NEVER use alcohol or other solvents.

Improve your indoor air quality with your new germguardian® Air Cleaning System. Multiple levels of cleaning include a combination filter that captures allergens, and a Charcoal filter to remove odors. UV-C light technology enhances germ-killing.

Pre-Filter – Captures initial dust and allergen particles.

Activated Carbon Filter – Charcoal/Activated Carbon contributes to the control and prevention of the growth of bacteria, germs, and mold.

UV-C Light – UV-C light technology works with Titanium Dioxide (TiO2) to enhance the elimination of airborne germs. TiO2 is activated by the UV-C light to decompose the remaining odor molecules caused by smoking, cooking, and pets.

Pre-filter and Carbon Filter are combined into one layer that attaches to the Filter.
