Im not familiar with this generation or brand of filter.I have had unpleasant past experiences with filtering straws and similar sports bottle type filters.The straws proved ineffective and were recalled ( a few 'survivors' periodically pop up at gunshows,swapmeets etc)The sports bottles are of limited life and quality.I suspect the casual,JimmyBuffet Margueritaville advertising leads to a casual (read sick) user.You may want to compare unit cost and capacities against some of the units reviewed by Doug on this site.<br><br>
