Thanks for the info...kinda what I thought. I'm going to put some heat on Fresenius to install one of those here at our house. Sine my wife has "good" insurance-I think they'll play along. I mean, the cost of that filter certainly has to be less than the cost of replacing those damn SAK's every 2 or so weeks...
I told her that since my wife's insurance is paying for it, it shouldn't be an issue
It will be interesting to see how long the PAK's last now.
Did you get your replacement Linx already, SD?
