The filters applied to the ipuri have achieved a total of four stages of dust removal as well as a perfect
technology that is harmless to the human body and catches the smell

1

PRE-FILTER

It is a filter for pretreatment which removes more than 10㎛ of dust particles. By adding antibacterial substance, it not only removes dust, it also prevents the growth of microorganisms, bacteria and fungi that can reproduce inside the air cleaner and on the filter surface.

2

TRUE HEPA FILTER

It is the first air purifying technology which is developed to purify the radioactive particles in the air. It is the main filter for dust collection which removes at least 99% of the 0.3 μm size particulate, which is the most harmful to the human body, It is also a high efficiency filter that is used in semiconductor clean room.

3

STERILIZATION FILTER(N29)

It is the fiber of yarn which made nylon and acrylic yarn with copper sulfide nano-ion bonding technique by developing the best ion bonding technology in the world. Copper (Cu) has been found to kill more than 99% of pathogens within 2 hours of contact with a surface-contacting substance that has an antimicrobial effect (US Environmental Protection Agency). Copper (Cu) is one of the necessary nutrients needed not only for humans but also for plants and animals. It is harmless to the human body and is recyclable, is a complete environmental product.

4

ACTIVATED CARBON FILTERFILTER

By using the catalytic action on the activated carbon which has developed micropores, the specific surface area as the absortion treatment agent, the unpleasant odor in life is removed, thus it is excellent in persistence of breathability and deodorization.
