Operating Your Air Purifier
On/Speed Control: Rotate the Speed Control knob to set the desired speed. A setting of
zero (0) indicates that the unit is off, one (1) is low speed, two (2) is medium speed, and
three (3) is high speed. The fan speed can be adjusted at any time.
Cleaning And Filter Replacement
1. Clean the outside of the unit with a soft, damp cloth. The front grille can be remov ed and
cleaned in soapy water. Remove the pre-filter before cleaning the front g rille.
2. At least every 90 days, open the front grille, remove the carbon pre-filter, and re-
place it. This is necessary to maintain proper odor-removing and overall filtration per-
formance. If necessary, it can be changed more often. Mark the new filter installation
sticker included with the new carbon pre-filter. Be sure to remove any plastic wrap-
ping that may be on the new filter before you place it into the Air Purifier.
3. While replacing the pre-filter, you should view the condition of the
QuietFlo™
HEPA
Filter. Compare the filter to the color coded chart that is on the inside of the housing. If
the filter matches the dark color on the chart, you should remove the filter and replace it
with a new f ilter . Mark the new filter installation sticker included with the ne w
QuietFlo™
HEPA Filter. Depending on use and environment, the HEPA Filter should last one
year.
4. If you notice a decrease in air output or an increase in noise, the HEPA Filter may be
clogged. Replace it with a new
QuietFlo™
HEPA Filter.
