Logics

Terminology

1-1. Negative ion

(1) What is a negative ion?

Atomic element in the air with negative electrons that releases a refreshing feeling. It can be found in a forest, waterfalls, thermal spring and etc. If the atom loses an electron, it turns into a positive ion. If the atom gains an electron, it turns into an negative ion.

(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 mell.

1-2. VOCs (Volatile organic

compounds)

(1) What is VOCs?

Carcinogenic substances that cause allergies or respiratory ailments, such as a paint, adhesives, spray, construction materials, wax, carpet, and etc. Unlike the general perception that only cheap construction materials emit VOCs, high quality new constructions may also emit VOCs. It may stay remained in a closet or inside of furniture even after several years.

Filters Introduction

(1) Pre-filter

One filter performs antibiotic treatment, anti mold 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 decomposes the ingredients which causes the allergy, having the allergy preventive effect also removing the odor and anti-bacteria effect.

(4) Washable HEPA Filter

HEPA filter polluted by acarid deadbody, pollen, 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.
