I like this 10 liter (2-1/2 gallon) water bladder here.
Also, I use this filter when I have hiked the PTC.
Thread this 32.oz. Nalgene water bottle onto the above MSR MiniWorks filter and it works much easier to filter the water.
Pretty good iodine tabs here with neutralizer that removes most of the taste and odor of the iodine tabs.
These folding 10 liter (2-1/2 gallon) buckets not only work well to let sediments or "dregs", if present, settle out of solution a bit before you filter but also allow you to take water to a comfortable location to do so.
