The 555 Pro Ion Generator is used to neutralize the smell in a closed room. The fan draws air from the surrounding air, guides it through the electrodes, and then blows it out of the socket gap and returns to the room for treatment. In this process, through the corona discharge that occurs between the electrodes, the oxygen in the indoor air is converted into singlet oxygen (O2), and then the odor molecules are oxidized and degraded.

This equipment is a plasma field generator, which in addition to singlet oxygen also produces a very small amount of ozone (O3)(max.0.05ppm/m3). These amounts amount of ozone (O3) are not harmful to health. The odor neutralizer can effectively remove odors such as kitchen or musty odor, smoke odor, or residual odor after fire. The device has been designed and tested in accordance with applicable safety standards.
