The 42 and 84 models have been developed specially to decrease highly evasive Legionella bacteria in water systems. The products are based on a chemical-free technology, which has been tested at the Vitens laboratories in the Netherlands. It meets the strict new BRL K14010 1/01 guidelines issued by Dutch quality assurance agency KIWA. The Vitens laboratories' tests prove that the powerful free radicals created by the Wallenius AOT 42 and 84 are even effective against Legionella bacteria which live inside amoebas.
The choice between models 42 and 84 is determined by the degree of contamination in the water and the desired degree of purification.
