FILTERS AND FILTER
OPERATION
The Dustblocker 650 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.
At the front of your Dustblocker 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
removing the two lock pins at the sides
and pull the lter out. At the top of
the 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 :
