 Phil: If you use a water bladder, consider the inline filter that is made by 
 Safewateranywhere.  It weighs in at under 3 ounces and will filter up to 200 
 gallons before it needs to be replaced.  I did the same calculations that 
you 
 did and when you factor in the wt of the water that must be carried, or the 
 amount of time that you have to sit around and wait for the water to treat, 
 with the wt of the Pur Hiker and the wt of the SafewaterAnywhere filter, the 
 inline filter cannot be beat.  Its packaging claims to rid the water of 
 Giardia.  They usually go for at or under the cost of a new filter for the 
 Pur Hiker

The pore size is 2 microns. To big. It will filter out Giardia (need 4 
microns or smaller.)

For optimal results, always select a filter with a pore size of no greater 
than 0.4 microns if you expect it to protect you from bacteria such as 
cholera, typhoid, and E. coli.
