Problem/
Question
Possible Cause/Remedy
Why do I need
to replace the
atomiser at
regular inter
-
vals?
There are two reasons for this:
1. To guarantee a therapeutically
effective particle spectrum,
the nozzle holes should not
exceed a certain diameter.
Due to the thermal and me
-
chanical stresses, the plastic
is subjected to a certain
amount of wear. The nozzle
attachment [10] is particularly
susceptible to this wear. This
can also cause changes to
the droplet composition of the
aerosol, which has a direct ef-
fect on the effectiveness of the
treatment.
2. You are also recommended
to replace the atomiser on
a regular basis for hygiene
reasons.
Does each per
-
son need their
own atomiser?
This is absolutely necessary for
hygiene reasons.
