Legionella infection occurs through the lungs. You can only become infected if you inhale contaminated droplets of water spray. For example, in showers or bubble baths, near wet cooling towers or wastewater treatment plants. 

Extra risk in recreational vehicles:The legionella bacteria grows in water with a temperature between 20 and 50 degrees Celsius. If the water is released into the air in tiny droplets (mist), someone can inhale the bacteria and become infected. The bacteria naturally occur in soil and water. So be aware of the water in the tank of your vehicle or vessel, especially if you are on the road in summer conditions. Then the temperature in the tank, but certainly in the pipes, can quickly rise to higher temperatures, resulting in a greater risk of legionella contamination. With Tank-O3 you protect yourself against this!
