Will my Doulton or British Berkefeld filter element remove Legionella?

Since Legionella has a similar morphology to E-coli our ceramic filter elements should provide similar protection against Legionella. However, Legionella is capable of slow regrowth downstream of the
filter, so if just one organism passes through the ceramic it could eventually colonise the water delivery system. Therefore it is important to regularly disinfect downstream of the filter or fit a UV light just after the filter.
