What is a good water purifier (non-chemical). I've been looking at the Steri-pen as well as the pump types. Anybody have any experience with the Steri-pen?

There are others like the Sawyer that is a bottle with filter built in. It can be adapted to hook up to a hydration bladder or funnel.

There are other similar "pumpless" types that I'm sure others can recommend.
I haven't tested the Sawyer, but I got one to use on the faith that it will work.

You'll also want a filter that you can carry close to your body in freezing weather to protect the filter.

Steripen was nice. But I didn't like the small quantities of water it purified and the battery life. There is a hand-crank unit that takes care of the battery life problem now but it is bulky though:



But it still requires you to pre-filter the water to get the sediment out. If I have to filter, I might as well get a filter LOL I also didn't like that if I damaged the glass bulb, there would be no more water. It was a good "backup" though also in case viruses were a problem.

The Steri pen/wand deal kind of scares me, Personally I cant make myself trust it. What I do trust is a Katadyn Hiker pump, its amazing, quick and easy to use. Well, its great in the mountains, not so good in desert environments. But when shopping for any pump make sure the filter goes to 1 micron "absolute" and is not 1 micron "nominal." Giardia and Cryptosporidium are no fun

I use the Katadyn Hiker Pro thing, it does the job just fine. Looking to get a smaller version (like mentioned above). You always want smaller camping gear, the longer you go.

Neither are purifiers though. There is a difference between filter and purifier. Filters remove sediment and bacteria. Purifiers may or maynot remove sediment but will kill 99.99999% of bacteria, cysts, and viruses. Filters do not generally remove viruses.

Katadyn pocket and hiker pro have limited virus protection.

I use the Katadyn Hiker Pro also, and have never had a problem. Used the Pure before that and since it is the same Co. now; I have 10+ years with one.

Used one of the Ceramic Katadyn's for about 20 years. They work great but are a little heavy for a one person hike through adventure. They are not cheap at around $200+. I forget what they are called but I keep it in my group camping kit.

If you are worried about virus etc. just carry a chemical treater and a filter. It has worked for me, and I have watched allot of people get sick using gear they thought would work. I would laugh at them, but when the reality sets in that now they are holding me up, I drop back and punt.

The most natural and long term filtration system is the ceramic "bowl" filter which is being mass produced for poorer countries. It is silver impregnated, and then baked on a n oven, and is gravity fed water, which passes through and drips into a container. You can get ceramic water filtration cartridges from berkey, and others, but they don't last very long in comparison to the bowl style, because the cartridges are so thin, that after a few cleanings, they "wear out". The bowls are made very thick, and should last longer than a human life and cost around $35USD, if you could get one.

but if you want one for your home the sawyers point one is the way to go for long term water filtering

the point one is on my list and should be getting it in the next few months as it comes up on the list

Man, you should read the manual.
"Purifier" what are you drinking?-space rations on a daily basis?

Most military installation trust the katadyn pocket. I used it 15 years in the military, now I use it everywhere I go, especially in africa.
Ok, 800gr are a kinda heavy- but it pays of itself. its different than those flimsy plastic units.

By the way you always can boil the water, and/or treat it with Micropur forte afterwards.

actually the most natural and most effective filter in 3rd world countries is a sand filter

i was planing on makeing one of these until a seen the sawyer point one i like how small the point one is . i can easily stash it in a dresser drawer until its needed. i also like how easy it is to put one together. a sand filter will be big ,heavy,and bulky

I'm in agreement with this filter. I have tried several and though its a little on the heavy side if your a backpacker, its a Great cross-functional filter for mulpitple uses and well worth its wieght in a pack

My primary filter is the Katadyn Pocket filter also. But I know for a fact that the Pocket and the Hiker Pro are not Purifiers. Just filters. Here is the product info page: http://www.katadyn.com/katadyn-produ...atadyn-pocket/

Viruses smaller than .2 microns can still get past the filter. Though not common (especially in the states) it can be a problem later.

But like you said, you can just boil it. I use the Pocket Filter and if I am worried about viruses overseas, I hit it with a Miox solution.

I have a sawyer in my "backups" box. I like the technology. Just a word of caution that it MUST not freeze. Frozen water crystals will damage the membrane and render it unsafe. The part I do not like is that you wouldn't even know if it was busted or not.
