Replacing the HEPA Filter

The HEPA filter will normally last about 12 months before it must be replaced, or approximately every fourth time the carbon pre-filter is replaced.

If the filter check gauge indicates that the filter requires replacement, it is recommended that you first replace the carbon pre-filter and then use the filter check gauge to check the filter again. If the colored cylinder still does not float up the gauge, the HEPA filter must also be replaced.

1	Turn off and unplug air purifier.
	Remove the used HEPA filter by
	gripping the sides and pulling
	outward, as shown. Discard the
	used filter. It cannot be cleaned.
