Greetings

We greatly appreciate your purchase of ChungHo Nais air purification system “IGUASSU D·H·A”.

IGUASSU D·H·A is designed and programmed in accordance with industrial standards. Applied 4 stages of filter system (Pre-filter, Antibiotic filter, HEPA filter and Deodorization filter) make it possible to remove fine dust as small as 0.3

㎛, formaldehyde and volatile organic compound which are one of the causes of

Sick House Syndrome and ammonia, acetaldehyde etc. Antibiotic filter includes extract from ginkgo leaves.

It refrains mold and germ from increasing. Released Cluster Ion helps to eliminate germs and virus more effectively. Natural humidifying method using rotating disc makes the indoor optical humidity.

Please read the instruction manual thoroughly and keep it for a future reference.
