When To Change The Exhaust Filter - Miele S 5981 Operating Instructions Manual

Maintenance and care
When to change the exhaust
filter
Always change the ACTIVE HEPA filter
when the filter change indicator (Reset
button) lights. It is designed to light
after approximately 50 hours of
operation which is about a year of
average use. You can continue to
vacuum. However, the suction power
will be reduced as will the effectiveness
of the filter if it is not replaced.
You can replace the "ACTIVE HEPA"
filter supplied with the cleaner with a
"SUPER air clean" or an "ACTIVE air
clean" filter (see "Exchanging exhaust
filters").
