Important Limitations of Filter Load Indexes
The concept of filter load indexes allows for a more precise calculation of the remaining filter life
than with regular filter life counters. Yet, the determination of filter load indexes underlies in its
definition some natural limitations. This is why it is important, especially if there is a noticable
decrease in filter performance, to change filters ahead of the indicated filter life. In such a case, it
may be necessary to adjust the appropriate filter load settings to a higher value.
The manufacturer continuously collects laboratory and field information to make the adjustment of
the filter load indexes even more accurate and simple. From time to time we may update our
registered customers with additional information in this regard.
Tobacco smoke
The amount of tobacco smoke in your air cleaner’s application environment can have a significant effect
on filter life.
If tobacco smoke exposure is regular, the following values should be added to the appropriate filter load
indexes:
Tobacco smoke presence Large Dust Index Fine Dust Index Gas Index
Low + 1 -- + 1
Medium + 2 + 1 + 2
High + 3 + 2 + 3
Very high + 4 + 3 + 4
Dusty environments
Environments with a high dust content may shorten the life of the pre-filter. If there is a frequently high
dust content in your environment, add the following values to your index setting (Tobacco smoke
exposure should not be used for the definition of a “dusty environment”):
Dust presence Large Dust Index Fine Dust Index Gas Index
High + 2 + 1 --
Very high + 4 + 2 --
Presence of volatile organic compounds
Volatile organic compounds may be set free from solvents, paints and varnishes may influence the life of
the activated carbon filter in your unit.
If there is a regular presence of solvent vapours or similar organic compounds, it is recommended to
add the following values to the Gas Index (Tobacco smoke exposure should not be used for the
definition of an “organic presence”):
Organic presence Large Dust Index Fine Dust Index Gas Index
Low -- -- + 2
Medium -- -- + 3
High -- -- + 4
