Your opinions: Best filtration systems
« on: September 24, 2013, 01:47:55 PM »
I'm curious what yall prefer to take with you for filtering/purifying water.

For my last trip in the Pecos Wilderness, with fresh high altitude streams/lakes, I liked using Katadyn MicroPur drops. Packed away to nothing, easy to get going and put back away. Takes awhile for water but if you have some 1-Liter bottles along with your bladders, you can get a good refill rotation going.

I'll be doing the OML this winter and will be expecting less already-clean water. What filter systems work well with drawing water from small pools or trickling streams? I'm looking at a sawyer or MSR gravity filter, but what do yall think?

Thanks and Gigem

If you search around the site, you'll find several threads on this subject.

I've been using Aquamira chlorine-dioxide tablets in BiBe for almost 10 years, with no problems. This includes some still, scummy, or stagnant water that required some form of filtering before treatment. I use a bandana (or two, if necessary) to pre-filter. No extra weight or bulk, as I'm carrying the bandanas for other reasons anyway. I use a bailing cup to pour through the bandanas into a 1-quart Nalgene (typically carrying 2-3 of those between my wife & myself). Then from the Nalgene into a Platypus for >1-quart bulk tablet treatment. The bailing cup has been (at times) the bottom portion of a box-of-wine, or it could be our flat-packed Orikaso cup or bowl, both of which we're carrying anyway.

I once shot a man in Reno -- wait, that's not right...   :eusa_whistle:

Oh yeah, I once filled & treated a couple of gallons of water from Fresno Creek in the time it took another guy to pump 1 quart. A filter/pump in BiBe is unnecessary extra bulk and weight (in my opinion, of course), and they will fail notably if there's any grunge in the water.

This is a pretty "hot" topic though. Some BiBe regulars here would agree with my approach, others are very loyal to their filters & pumps...

In the past, I have used a Katadyn Hiker Pro filter/pump. On our last trip, I took along some Katadyn MicroPur tablets. Since the pipe was running at Boot Spring, it was easy to just fill and treat. If you can find them, they work great.

An alternative to the bandanna strainer: paper coffee filters.

Yep the Katahdin Hiker Pro

I use a MSR Sweetwater filter and sweetwater drops.  I also carry a small sea to summit collapsing bucket.  I scoop out water and move it some place to filter.  Easier than squatting next to a stream, trying not to fall in, and keep all the hoses in the right places.

Katadyn pocket filter. It's not the lightest. It's definitely not the cheapest. But I can absolutely depend on it to perform flawlessly for years of rough use.  I need to feel absolutely confident in my filter.

I am with trtlrock on this one, pre-filter with bandana and then aquamira drops like this



And yes, it can be a much debated subject.

I use the aquamira as well. I usually don't fret over a few floatees. Tried coffee filters and bandanas as prefilters but usually don't use them. Seems like with the filters we spent a lot of time filtering water.

I carry ClO2 tablets and a Katadyn Pro. if the water is chunky and I want to drink it immediately, I filter. If it's clear and no rush, the tabs are great. The tabs are my filter backup too. I've never had a failure with my filter, but I always clean, test, and lubricate it before and after every trip.

Usual recommendation for ClO2 is 4 hrs contact time but that is probably not required except at lower temperatures. It is important not to leave the water in direct sunlight during the contact time either.

I have had some commercial experience with UV and would NOT recommend Steri-Pen or equivalent. My experiences show that water turbidity greatly reduces the effectiveness of any UV system.

An old-timer told me once that you can put alum in a silty bucket of water and it will clear up in minutes..

I'm surprised at how many use Aquamira drops. Those are actually what I had with me in NM (I misnamed them as Micropur in OP). I thought they did great but figured they'd be the odd one out. Good to know those work well in BB with some sort of prefiltering process.

If you haven't tried the tablets yet, you might want to. They are soooo fast to deploy. Whip out the swiss army knife scissors, cut the small, square, individual hermetically sealed tablet-pouch, drop in container, shake, stow away, keep on hiking...

And, yes, the bandana(s) only come out if needed -- I don't mind a few minor flecks either.

This I will definitely do.
