We are leaving on a world cruise on a Farrier F39.
We have a Spectra Ventura 150
Considering a Katadyn back-up. Loww on cash and thinking of purchasing a used one then a new membrain.
Are there PUR/Katadyn units that you would stay away from? (EG. the Powersurvivor 35) or one in paticulare you would go after?
I am thinking a Manual pumped back-up but open to sugestions.
Plan to be gone 10+ years
John and Melanie
Thanks!!!!
