The 4 hour wait time is only for very cold and opaque water (which is hardest to treat). Water that is clear only needs 30 minutes (same as Potable Aqua)

Here is the treatment chart for MP-1 (Chlorine Dioxide).



It's worth keeping in mind that standard Potable Aqua is an iodine based treatment, and iodine is ineffective against Crypotsporidium. Whereas, Chlorine Dioxide will kill Crypotsporidium. That's why Chlorine Dioxide has become the new standard (and why even Potable Aqua has introduced their own line of Chlorine Dioxide tablets).
