FILTERS AND FILTER
OPERATION
The Dustblocker 450 separates the dust in three phases:
During the first phase, the G3 front filter is used. The filter collects the larger dust
particles and protects the G4 Pre and HEPA Filter.
The second phase is a G4 Pre Filter which collects the finer particles and protects
the HEPA Filter.
During the third phase, the HEPA Filter is used. This filter will collect the dust that is
dangerous for people's health and that is not visible to the naked eye.
The G3 front filter which sits behind the metal mesh needs to be replaced on a
regular basis according to the contamination of the air in the environment. This will
lengthen the life of the G4 Pre Filter and HEPA filter.
Inside of your Dustblocker, inbetween the G3 and HEPA Filter, you will see a G4
Pre Filter. If the machine is used daily we recommend changing it twice a year.
Of course this depends on the contaimination of the air in the environment. If you
regularly replace your G4 Pre Filter you will lengthen the life of the hepafilter.
It is simple to change the filter by
unlocking and opening the top lid of
the DB450, after which you can pull
the bar holding the filters in place
towards you. You are now free to
remove and replace any filter. At the
top of your G4 Pre Filter you will find a
label with the item number (Compare
this number with the number on the
old filter). Make sure that you place the
filter as indicated on the label:
