Pick the Right Water Filter
As an Eagle Scout, I have seen many water filters on my expeditions into the wonderful wilderness. Many of these utilize a pumping mechanism to push water through the filter. I have taken my turn alongside the others in my troop to supply us all with fresh water on a trip. So I can say that the best filters are the ones that have a pumping mechanism that you push down on. Some devices have a handle that you squeeze as if making a fist. These are not fun to use at all.
I found that the best way to pump water was to use the filter you press down on. I would pull up my camp chair next to the water source and then I could sit there for an hour pumping. I put the bottle I was filling in between my feet so it would not fall over. Then, I would sit the filter on my knee or on the ground next to my feet. By doing this, I could use my body weight to push the pump. This made a significant difference and kept my arms from getting tired.
