I think this the primary reason that chemical treatment makes the most sense after filtration as opposed to before.

My only concern with the chemical treatment / filter straw set-up is that you'd end up doing things in a somewhat backwards manner; you'd have to chemically treat the dirty water and then filter it.

For myself, I'd probably forego the filter straw and simply chemically treat the cleanest water I could collect with a simple pre-filter (bandanna, coffee filter, etc).
