Under Daily Purifying Modes, it automatically maintains a low level of ozone for safe daily air purifying, deodorization and bacteria sterilization, making the air you breathe fresher and purer. There are 6 Daily Purifying Modes with increasing levels of ozone from 1 to 6 to suit various room sizes (see chart below). You simply set it according to your room size in one of 6 modes and forget about it. Increase the level of ozone by selecting a stronger mode when there is constant source of contamination such as smoking. The unit comes with a Remote Control that let you control the unit conveniently from anywhere in the room.

This air purifier does not rely on air filters. It uses a near-silent Air Fan (CFM: 52) to distribute ozone gas through out the area to purify the surrounding air completely and quietly.
