AirZone 103T Air and Water Purifier pumps ozone into either air or water at the rate of 250mg per hour. The ozone is fed into water by means of a pipe and an air stone. The maximum quantity of water that can be treated is 250 litres per hour at 0.1 ppm. The ozone is produced by means of Corona Discharge. It is a table-top model and operates with the aid of a timer. Warning :  It should be noted that although ozone is an excellent oxidiser of pollutants in the air and excellent for cleaning fresh produce and flesh wounds, excessive amounts of ozone damage lung tissue so ozone should never be left running continuously, especially for deodorising air, while people are in the room. This unit, having the flexibility if working with air and water, can be used for these applications. Purify drinking water. Purify air. Deodorising rooms or cupboards. Skin ailments and wounds.  Smoking deodorisation.  Mould removal. Washing fresh foods. Making ozonated olive oil.
