Operating Your Air Purifier
Ionizer: Press this button to turn ‘on’ the ionizer. When the ionizer is ‘on’, the
green light near the button will be illuminated.
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.
Filter Change Calendar: The filter counter is de-
signed to optimize the performance of the air purifer
by reminding you when to change the HEPAtech Fil-
ter and pre-filter.
HEPAtech Filter Calendar: The HEPAtech Filter
indicator is located at the top of the calendar ring. To
set the HEPAtech Filter counter, rotate the calendar
ring to align the month that you installed the filter
with the top indicator. Since the filter is designed for
6 months use, the two indicators will serve as remind-
ers to change the filter every 6 months.
Pre-filter Calendar: The inner knob of the filter
counter is the pre-filter counter. To use, align the knob with the month that you
installed the pre-filter. The replace symbol on the inner knob points to the month
in which you should install a new pre-filter. The pre-filter is designed for three
months of usage.
Cleaning And Filter Replacement
1. Clean the outside of the unit with a soft, damp cloth. The front grill can be
removed and cleaned in soapy water.
2. At least every 90 days, open the front grill, remove the carbon pre-filter, and
replace it. This is necessary to maintain proper odor-removing and overall
filtration performance. 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 wrapping 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 HEPAtech
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 filter. Be sure to remove any plastic wrap-
ping that may be on the new filter before you place it into the Air Purifier.
