Personally I would just buy some packages of aquamira tablets at REI, throw two of them in the bottle and let it sit for 15 minutes and you are set.
If the water is a little more suspect, check out the Sawyer Point One filter (it is a squeeze filter)
IMO pump filters are totally unnecessary for single person use and are a PITA to maintain and clean. And I am leery of any kit that requires batteries to work, although the MIOX does work great
