Hi Mark, when we got our 1st caravan the filter in it was in a horrible state, took it out and threw it away, replaced it with a new one, had that 'van for 3 yrs, ,didn't change the filter in all that time, how ever I did sterilise the system every year.
have done the same with our latest 'van, I know that quite a few folk don't use a filter at all but personally I prefer to have one in, more of a security blanket than anything else though
