ELECTRONIC FILTER CLEAN REMINDER
Check Filters Button – When it is time to check and clean the filters, an indicator
light will illuminate. When this light comes on, you will need to clean the primary
ifD
®
filter and clean or replace the pre-filter. (See Filter Cleaning instructions on
pages 4-5). It is recommended that you periodically check the filters.
Depending on operating conditions, the filters should be cleaned every 3 months.
If you have chosen to use the Odor & VOC Reducing
K
Pre-filter, it is NOT
washable and should be replaced after 3 months. After you have cleaned or
replaced the filters, you will need to RESET the Electronic Filter Check.
To RESET the Electronic Filter Check:
After the ifD
®
filters and pre-filter have been cleaned/replaced and re-installed in the unit, plug the unit
into the power outlet with the unit remaining in POWER OFF mode, press and hold the CHECK FILTERS
button (see Fig. 5) for 3 seconds. The CHECK FILTERS LED will flash twice indicating the filter check
has been reset. The LED will no longer be illuminated.
The intervals are intended as guidelines only. Performance of any filter media is dependent upon the
concentration of contaminants going through the system. High concentrations of contaminants such as
dust, pet dander, and smoke particles will reduce the useful performance of the filter and they may need
to be cleaned more frequently.
Drying:
• Shake the filters to remove any excess water.
• Place the filters with the honeycomb side down on a plush towel.
• Note that the filters may still be discolored even after washing.
This is acceptable and will not affect performance.
• Allow the ifD
®
filters to dry for a few hours or overnight.
• When the ifD
®
filters are completely dry, place back into the air purifier.
CAUTION:
• Never place wet ifD
®
filters in your air purifier.
• The ifD
®
filters are NOT dishwasher safe. DO NOT place the ifD
®
filters in a dishwasher or subject them
to other extreme hot water conditions.
• Do not use any solvents, strong cleaning agents or flammable liquids to clean the ifD
®
filters.
CLEANING THE IFD
®
FILTERS (Cont)
The pre-filter helps capture large airborne particles that
enter the rear grille. This pre-filter can be periodically
removed and shaken to clean it. Alternatively, it can be
rinsed by hand under warm water (Fig. 8). Let the
pre-filter air dry completely before inserting back into
the grille (Fig. 9). If you need to replace this item, please
call 1-800-477-0457.
OPTIONAL: Changing the Odor Absorbing Pre-Filter
If you choose to use the odor absorbing
K
pre-filter that came with your air
purifier, it will lose its effectiveness for odor absorption over time and will
need to be replaced.
To purchase additional
K
pre-filter, see Accessories and Replacent Filters
section below.
To install it in the unit, simply place it securely into the rear grille held in place
with plastic tabs in lieu of the standard pre-filter as shown in Fig. 9.
If using the odor absorbing pre-filter, it is recommended that you store the
original washable pre-filter in the event that you decide to use it in the future.
NOTE: The odor absorbing pre-filter is NOT washable.
