Great system, David!
Some people can't detect or don't mind the swimming pool taste of Micropur (or Aqua Mira). Others believe the chemicals actually improve water taste. But for those (like me) who can't stand the chemical taste -- you can reverse the order by first treating the water, wait 15 minutes, then filter the treated water through any inline filter -- such as the el cheapo Aqua Mira Frontier Pro.
Taste and gunk removal aside, one other major benefit of pairing chemicals and filter is the elimination of the long waiting period. It takes chlorine dioxide 15 minutes to kill/neutralize bacteria and viruses -- regardless of water temperature. However, cold water requires longer treatment time to kill protozoa (e.g. crypto) -- anywhere from 20 minutes to 4 hours if water if just above freezing!
With a filter, all you need is wait 15 minutes for the chemicals to kill off viruses and bacteria -- and your filter can then block out the larger protozoa. NOTE that the Frontier Pro by itself is ineffective in delivering biologically safe water because the pore size is too big to block bacteria (never mind the even smaller viruses)!
