The
Clean Air Optima CA-604
is equipped with a
Permanent Reusable White Dust & Anti-
Microbial Filter
. It consists of an inner cylinder, an outer cover and a number of small plastic and
ceramic balls. The plastic balls are embedded with nano-silver, an anti-microbial agent designed to
purify the water and destroy microbes such as bacteria and mould. The ceramic balls function to
soften the water by adhering to minerals that cause white dust. They also serve to remove any
unpleasant odour from the water. The filter requires cleaning about once a month or 1,000 hours of
use. See the
Maintenance section
of more information.
