Going to need more details...

- size? portable to a whole home system
- duration? do you need it for 2 days or 2 years

Katadyn Hiker Pro would produce enough water for that time frame: http://www.katadyn.com/usen/katadyn-pro ... crofilter/" onclick="window.open(this.href);return false;

MSR MiniWorks EX would also fit your requirements: http://www.cascadedesigns.com/msr/water ... er/product" onclick="window.open(this.href);return false;

And I have one of these Platypus filters as a backup in my GHB preps: http://www.cascadedesigns.com/platypus/ ... er/product" onclick="window.open(this.href);return false;

Look at the Sawyer point zero two water filter system or Platypus GravityWorks. For the amount of water required in a portable setting you'll be spending a LOT of time sitting there pumping away to get the required 4 gallons per day for your family, where as, in a gravity system you can be doing other things while the water gets filtered.

For us we currently have a Katadyn Combi and a couple monolithic ceramic drip filters for home use but soon will be replacing it with the Sawyer point zero two or Platypus GravityWorks - just can't decide which. The last thing I want to be doing is spending time pumping a water filter if there are other jobs that need to be done.

I'm using the Katadyn hiker, didn't see any real advantage to the pro. I compared both the hiker and MSR miniworks (listed above) and the hiker is an inch shorter and 2/3 the weight so I went with it.

Sawyer zero two

Fill 5 gallon bucket

Drink water.


Depending on the source, you may need some flocculation, the Sawyer can be backwashed to extend service life.

Owing to how it is built, freezing is a real issue. Once frozen, you have a tree ornament...

MSR mini works + Aquamria Drops or Aquamira Frontier Pro + Aquamira Drops

These 2 systems have been working great for me.

Or the simplest solution, filter with a rag then boil it.

Took the kids (7 and 4 at the time) out camping last year, a combination of backpacking and car camping. (Camp was w/in 20 minutes of the car) I brought a small pump filter, water treatment tabs, a pot to cook, and a coffee pot to boil water. The hand pump (not sure which brand) was small and took me a good 5 minutes of pumping to fill a 1000mL nalgeen bottle, it was in short, a pain in the ass. The pills took 4 hours to clean the water properly, guess I should have read the instructions before I got those at wally-world. Boiling was quick and painless. (but that requires fire and stuff)
After filling all the bottles with the pump the first day a couple of times I grew tired of it. Before I put the campfire out for the night I boiled enough water to fill all the jugs and a full coffee pot for the next day. Did this while stitting around enjoying the fire and the stars. IMHO boiling water was the easiest way to get clean water. If I wanted it cooled I put it in the creek to cool it down, or left it over night. If you want a pump I would make sure it puts out a decent amount of water for the effort that you put in it.

The simplest system I have found is as follows:

1. Sawyer Mini or Sawyer Squeeze. This filters down to 0.1 microns, removing all bacteria and particulates. Can be backflushed and will last a lifetime of use, far longer than any of the ceramic filters mentioned above. The former also weighs just over an ounce, compared to the heavy ceramic filters. I have Katadyn filters. They're nice but obsolete as far as I'm concerned because they require a pump (which adds weight and can fail), have a relatively short lifespan (except for the pocket, which still has a shorter lifespan than the Sawyers and costs four times as much), and the ceramic element is heavy.

To use: just screw onto a plastic bottle and squeeze.

2.
As a backup or in case I suspect viral contamination, I have a Steripen.

3. I also have a few chlorine tablets.

4. Finally I have a titanium cup that I can boil in if high-tech solutions fail.

All four of these together weigh less than your average pump-action Katadyn filter on its own.

edit: Oh, and I've used my Sawyer to filter for multiple people. The squeeze will filter at a rate of about 1 litre per minute.

edit 2: Someone suggested the Lifestraw. With the Sawyer Mini, I believe this to now be obsolete. The Sawyer mini is rated to last for 100,000 litres (compared to only 1,000 for the Lifestraw), and filters down to a smaller level than the Lifestraw will.

You sparked my interest and the sawyer point zero two 4L kit looks very promising, even filters viruses.

I have never used the Sawyer Squeeze but I don't see how it any different than my frontier pro with a platy bag attached. What am I missing?

Frontier pro filters to 3 microns. Sawyer Squeeze to .1 micron. When your life is on the line, I know which one I want.

Sawyer also has a .02 micron filter, albeit more expensive. Sawyer filters do not filter dissolved solids (heavy metals or chemicals), so they are not a 100% foolproof filter, but in combination with my Berkey, or any other charcoal/ceramic based filter, I am fairly confident that I can get potable water from anywhere in the world.

Additionally, the sawyer filters will last for a lot longer.

edit: I used my Sawyer Squeeze every day for two months while I was in Canada. Backflushing only once or twice during the entire trip, and it's still good as new now. I could filter drinking water with this every day for the next 50 years (36,500 litres) and still have something like a hundred lifetimes of use left. They have a 1 million gallon guarantee!

Sawyer squeeze is my go to filter and I have abandoned all my pump filters. I also like the Platypus GravityWorks for large groups and family use if you don't want to build your own inline system. It can process a lot of water quick and easily, especially if everyone in your party is using Platypus bladders.

I picked up the Sawyer Squeeze for my commute bag, but have yet to use it. Seems like a quality product and is very light. I don't know how well it would do compared to the base camp supplying water for the whole family though... The base camp does that very well, and I have 4 extra filters in my stores now. I also added a waterproof note pad to it and write down every time I fill it do I can approximate filter life. As I see it I can filter 5000 gallons.

The life straw version 2 soon to be released to the public also filters down to 0.02 micron, although it is already behind the curve of the sawyer and their fantastic 1 million gallon guarantee.

Can anyone recommend a good charcoal filter to accompany these water filter systems?

Katadyn make a charcoal filter extension that just adds onto whatever you're using (well, you need tubing).
