FILTERS AND FILTER
OPERATION
The Dustblocker 450 separates the dust in three phases:
During the rst phase, the G3 front lter is used. The lter collects the larger dust
particles and protects the G4 Pre and HEPA Filter.
The second phase is a G4 Pre Filter which collects the ner particles and protects
the HEPA Filter.
During the third phase, the HEPA Filter is used. This lter will collect the dust that is
dangerous for people’s health and that is not visible to the naked eye.
The G3 front lter 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 lter.
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 hepalter.
It is simple to change the lter by
unlocking and opening the top lid of
the DB450, after which you can pull
the bar holding the lters in place
towards you. You are now free to
remove and replace any lter. At the
top of your G4 Pre Filter you will nd a
label with the item number (Compare
this number with the number on the
old lter). Make sure that you place the
lter as indicated on the label:
