Hey guys, I'm in the market for a water purification system for some backcountry hunting. My plans are to be out anywhere from 2-8 days, and trying to stay as light as possible. The areas I hunt have plenty of water sources, so I expect I will only have to refill on water 1X per day. Does anyone have a favorite purifier for these types of situations? Trying to keep it small so I still have plenty of pack room for other goodies.

Sawyer Squeeze filter

coupled with Chlorine Dioxide tablets

Use the tablets for most applications. Use the filter for really murky water.

That looks really interesting. I like the bag Idea for size/weight savings, and the price isn't bad at all compared to some of the MSR offerings. I think I'll give these a try this off season. Thanks for the response!

One thing to think about. It's not easy to fill the water bag directly from a stream. You will need something (a cup) to scoop water and pour it into the bag.

I use a spare bag, cut in two, and rolled up with the water bag and filter as my "water scooper."

I've been using the MSR Sweetwater since it came out many many years ago for all my back packing/camping needs.
Must work as I have yet to get sick from water.

have you thought about a steripen ? we used them for about 20 days last fall on a pack in hunt . seemed to work , nobody got sick .

I started out 50+ years ago filtering water through multiple layers of bandana, then drops of iodine, drops of bleach, Halazone tabs, FirstAlert filter, and now the Sawyer products. Never tried a Steripen, but they seem interesting. Everything seemed to work. Just depends on how much you want to carry.

Nothing will be perfect for every situation.

Are you looking for a microfilter or purifier? For purifiers you're looking at a steripen, iodine, chlorine dioxide, and high price tag pumps like the MSR Gaurdian ($350), or a combination of a pump and tabs.

Most places a microfilter is more than enough. There are some great gravity fed ones that are getting nice and compact

Just about all the pumps by MSR and Katadyn seem to be great.

Your lightest option and what I still use more often than not is:

I use one tablet per quart if I get it from a clear flowing source, 2 if it's dirtier water or from a non-flowing source

They make a pre-filter for the Steripen to filter out the particulates before you purify the water with the device.

Remember to dry your filter out if it is going to get below freezing, when the water turns to ice and expands it will ruin the filter.
