>>2706139There are a lot of different options which vary in effectiveness, size, weight, and filtration. The big pump ones you throw out can often handle murky/silty water better, but are bulky and heavy, and won't work on trickle water sources.
The smaller ones like the sawyer squeeze or the platypus quickdraw you have to push the water through and depending on the amount of crap in it, you may have to back flush.
Gravity filters are convenient and easy, but you have to wait around for it to filter. Good for when you make camp each day and you can prep water for the night/next day.
Aquamira/purification tabs work well, but they take a good amount of time and do nothing to remove sediment from the water. They are nice if you grab some water but don't need it for awhile so you just pack the water with you and let it treat as you go.
Steri pens/UV light filters work well and are relatively quick, but your mileage may vary with very murky water. You also only get so many charges out of one before a recharge (battery power banks are nice to have in general though, and one charge should be wayyyy more than enough for one trip anyway).
If the water is murky you can try filtering it through something like a bandana to get the sediment out, but obviously still need to be concerned about bacteria.
I recommend getting a plastic hydration bag that opens up wide to collect water.
You can also always boil your water.
oh and don't do a long hike on new shoes. Break them in and carry moleskin.
