4.4.11 Filter Load Index Setting

The lter load indices are used by the lter life monitor for a more accurate calculation of the remaining lter life. The

lter load indices are based on air pollutant groups that have particular impact on the life of the IQAir® system’s

lters. Each index can be adjusted to reect the pollution levels in a certain indoor environment.

The Filter Load Index Menu allows to view and modify the lter load indices for:

• Large Dust

• Fine Dust

Large Dust Index: This index is based on the group of coarse or heavy dust. This dust can contain particles 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 bers, pollen, spores, dander, wood dust, etc.

Fine Dust Index: This index is based on the group of ne 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.

4.4.11.1 Determining the Filter Load Index

The setting for each of the lter load indices can range from “very low” to “very high”. The system is supplied with

the following default settings:

• Large Dust Index: average

• Fine Dust Index: average

There are a number of factors that may make a modication of the default settings necessary in order to ensure the

most accurate lter life display possible.

Tobacco Smoke

The amount of tobacco smoke in the room air can have a signicant effect on lter life. If tobacco smoke exposure is

regular, the filter load indices for each pollutant group should be adjusted to “high” or “very high”.

Dusty Environments

Environments with a high dust levels are likely to shorten the lives of the pre-lter and the HEPA-lter. If there is a

frequent high dust content in your environment, set the Large Dust Index to “high” or “very high” (Tobacco smoke

exposure should not be used for the denition of a “dusty environment”).
