840129900 ENv02.qxd 11/1/04 11:02 AM Page 11 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. 2 Obtain a replacement HEPA filter. Insert the unwrapped HEPA filter, hook fastener side out, into the air purifier. NOTE: Improper filter installation will result in poor air filtration. 11
