The sawyer mini gets a really good press all over this type of forum.
I have a Water to Go bottle which you fill up and then drink direct from the bottle as and when needed. I also own two life straws, (do't ask,) which are unused though I do carry one just in case, sometimes. Before I walked in Spain my son got me a Revive H2O collapsible filter bag, which I did use as a back up to my Water to Go Filter bottle. It just fastens to the back of my knapsack with a caribiner. I do use this sucking through the filter as & when required.
The reason I like these type of filters is that you can just fill and go. I don't use huge quantities of water (two litres a day is about my limit if I want decent night sleep
) But then again your sawyer would fit a collapsible water bag and then you would not need to hang about waiting for it.
