Filter Cleaning - Clean Air Optima CA-704 Gebrauchsanweisung

Replacing of filters
The Clean Air Optima CA-704 / CA-707 is equipped with a filter lifespan surveillance mecha-
nism that signals that the filter (HEPA + Activated Carbon Filter) have to be replaced after 500
working hours. To show that the filter need to be replaced, the dehumidifier emits a double zero
indicator light. Reset the timer for the filter by pressing and holding the laundry button
for about 3 seconds. If the indicator light goes out, the timer has been successfully reset.
Depending on the use, the Activated Carbon Filter and True HEPA H13 Filter has a lifespan of
approx. 3 – 6 months. The Pre-filter and UV-C lamp are permanent, no replacement needed.
Take out the filters from the filter frame compartment. After filter replacement or filter
cleaning reinstall the filters back into the filter frame compartment and assemble back to the
device, see the illustration below.

Filter cleaning

The best effect for a longer lifespan of the Filters is reached by cleaning the filters once a
month. If indoor air is extremely polluted, we advice to clean the filters more often ca. once per
two weeks.
Clean the Pre-filter, Activated Carbon Filter and True HEPA H13 Filter carefully with a brush or
your vacuum cleaner. That way bigger dust particles like lint, hair, dust and dander of pets can
be removed from the filters.
