  4. To clean the permanent HEPA-type Filter, use the brush or crevice attachment with a vacuum cleaner. Run the attachment along the inlet and outlet side of the filter, cleaning between the crevices as much as possible. Do not use water or any household cleaners or detergents to clean the permanent HEPA-type Filter.
  5. Once the permanent HEPA-type Filter has been cleaned and checked for any possible damage, replace the filter back in the reverse direction described here. Plug in the unit and hold down Time + Power On button for 3 seconds. The clean filter light will go off and your cleaning maintenance is done.

Cleaning External Surfaces

  1. Turn off and unplug unit.
  2. Use a washcloth slightly dampened with a little water and dishwashing soap to wipe the outer case surfaces.
  3. Do not allow water to slip into the internal parts as this could damage your unit and result in electrical shock and injury to you.
  4. Allow the unit to thoroughly dry before use.

UV Lamp

The lifetime of the UV lamp is up to 12 months of continuous, effective operation. After this time, the bulb may remain illuminated, but its effectiveness is greatly reduced. For maximum effectiveness, please replace the UV bulb annually. If the lamp stops functioning or needs
replacement, please visit our web site at to order a replacement lamp. Or call 1.800.875.8577.


• Do not touch the glass part of the lamp. Oil from fingertips will decrease the effectiveness of the lamp.

lamp will result in severe damage to eyes and could cause blindness.
