3.3.8 Filter Load Index Menu
Chapter 3 Using the Control Panel .
The Filter Load Index Menu allows you to view and modify three filter load indexes:
- Large Dust Index
- Fine Dust Index
- Gas Index
3-12
The filter load indexes serve as information input to the filter life monitor about the room air
pollution and the resulting pollution load on the unit’s different filter elements. The filter load
indexes are used by the filter life monitor for a more accurate calculation of the remaining filter life
(see page 3-15).
The filter load indexes are based on air pollutant groups that have particular impact on the life of
your air cleaner’s filters.
LARGE DUST INDEX: This index is based on the group of coarse or heavy dust.This dust can
contain fibers with several millimeters in length down to particles a mere 0.003 mm in size. This
type of dust will generally settle within an hour after generation or agitation on top of surfaces. It
consists of fibers, pollen, spores, dander, wood dust, etc.
FINE DUST INDEX: This index is based on the group of fine dust particles.This type of dust is
smaller than 0.003 mm (3 µm) in size and will remain airborne for long periods of time. This dust
group is made up of small combustion particles that are created as the result of combustion
processes of automobiles, small allergen particles such as cat allergens, tobacco smoke particles, etc.
GAS INDEX: This index is based on the group of gaseous organic compounds.These are organic
chemicals that are present in the air in the shape of gas molecules. This group contains
hydrocarbons, such as benzene, decane, formaldehyde, perchlorethylene, styrene, toluene and
xylene.

3.3.8.1 Determining and Modifying the Filter Load Index
The setting for each of the three filter load indexes can range from 1 and 9. Index setting 1
corresponds to the lowest, and 9 to the highest anticipated filter load.Your IQAir cleaner is supplied
with the following default filter load index settings, which correspond to use in an office or home
environment with average air pollution levels:
Large Dust Index: 4
Fine Dust Index: 4
Gas Index: 4
There are a number of factors that may make a modification of the default index settings necessary
in order to ensure the most accurate filter life display possible.
