An excellent thought, especially after reading the patent details more 
thoroughly. I quote here from one of their examples.

<<If the well water contained very low levels of lead or chromium, the 
molecular absorption media's performance was enhanced by a prewash with a 37% HC1 
solution. The prewash removed various trace products normally used to stabilize 
the filter media but which interfere with the removal of very low levels of 
lead and chromium, i.e., 3-5 .mu.g/l (ppb). >>
