(2) The platinum three-dimensional anti-
bacteria system.
99.9% highly purified platinum catalyst filter
completely removes those factors which could
cause the sickhouse syndrome such as VOCs,
harmful chemical element and its smell.
1-2. VOCs (Volatile organic

treatment, and dust removal, providing a purified
air.
(2) Photo-Catalyst Plasma Filter
Photo-Catalyst Plasma Filter removes
microscopic motes, odor, yellow-dusts, and
allergy causing substance through a 3 stage
process, plasma generation part, dust collecting
part, and photo-catalyst filter
(3) Anti-allergic Filter.
The anti-allergic filter could absorbs and

small dust and float mildew, animal bodyhair etc.
can be washed.
(5) Washable Deodorization Filter
This filter was processed with activation treatment
for stronger adsorption function (characteristic of
charcoal). This deodorization filter has higher
level of negative ion, minerals, far infrared lays
generation ability than charcoal.
