The Water Pan

Water binds dirt and retains it. Wet dust cannot
fly any more. A HYLA works without paper filters.
There's nothing constraining the air flow passing
through the HYLA.

Paper filters have pores, and not only air escapes
through these pores, but also fine dust. Even in
the first seconds, these tiny pores clog up and
the power decreases rapidly - a sheer waste
of energy!

This is also the reason why a HYLA gets by with
only 850 watts of power - thanks to water as
a filter, a HYLA can always breathe freely.
