(Ion quantity:88ft3/min, Humidity:19%, Temperature :23°C)Protection from harmful particles and viruses existing in the air :The hydrogen ion (H +) generated in the MPI device bonds with electron (e-) and changes into active hydrogenatom(H). Also oxygen contained in the air bonds electron to form the oxygen ion (O2 -).They control activeoxygen which can cause disease, cancer, and protect against harmful bacteria.MPI (Micro Plasma Ion)Active hydrogen /Oxygen ionsActive hydrogen and oxygen ionsare generatedHarmfulsubstancesCombines withHarmful substancesOH radical, Harmfulviruses and bacteria.HarmlesswaterTurns intoharmless waterchapter2_Indoor units(108~143) 3/14/08 22:37 Page 108
