Recently I purchased a 1968
Overlander International. It is ~95% original and everything appears to be in fair/good working order. Under the sink is a stainless steel canister for water purification. The label indicates that it is a model EN-1 distributed by Ewert & Ewert. A cursory survey of the internet reveals no hits for Ewert & Ewert or for an EN-1 type filter. It appears as though it was never used, or exceptionally well taken care of. I see no need in replacing this filter with a new modern filter, if of course I can still get the necessary filters. So that is my question, has anybody ever heard of this thing? And if so...where can I get replacement filters for it?
