Merging afterwards might have worked better.. LOL
Here is the Water Filter system that I use, based on Dialysis technology.
Sawyer Products http://www.sawyer.com/default.html http://www.sawyer.com/water.html Canadian Sales Company http://www.globalhydration.com/product-info/sawyer-sp183-4l-water-treatment-system The Distribute to Canada, see links for companies they sell to.
The one I bought is the Sawyer 3 Way Water Filter 
This is the next one I will buy for convenience sakes.Sawyer 4 Way Water Filter 
The Sawyer purifies water that is laden with bacteria, viruses and parasites. Berkey does that and Radon 222, Heavy metals,VOC's, inorganic minerals and Trihalomethanes.
Unless there is something I am missing on the site. I looked in the "The Technology section" on the site WildE provided.
Sawyer is far cheaper per gallon since it can filter enough for 34 lifetimes if you live to be 80.
This is not meant to be condescending, just a comparison.
If someone can find a purifier that can do the same or more than Berkey for the same price or less, let me know as I would more than likely purchase it as well. Can never have too much purification for water.
look at the filter 2 system and it covers those as well

Care to provide some guidance as it seems there is a lot to go through on that site. Thanks.
No need for the large font as it translates to yelling. I do not want to get into a argument. I want info that is all. Thanks.
And a gravity system since we are a preparedness site. RO needs pressure to run. Also I was referring to something you can stick in a BOB. I know I can get something that isnt a Berkey for a house that is just as good, that is not my concern.
Isn't there a Burlington Ontario company that came up with a water filter system that basically can take raw sewage and turn it into drinking water? I saw a documentary with the Canadian forces using it but I can't find anything on line about it. I believe the system used membranes for the filter.

Water filtering, Biomass
If the water stopped, and you needed more water than you have, would you know how to filter the water that you need. You have a rain barrel, but is that water good enough to or bathe with.
What I believe that every prepper should learn how to make a simple biomass water filter. Yes SIMPLE as in Keep It Simple Stanley. A small one is built the same way as a large one.
Materials: a container, 5 gallon pail or barrel (food grade best). Granular charcoal, bought or home made. (plain charcoal crushed to 1/8” or 3mm size). Sand, from the beach, or the bag don’t matter, just not sterile (a good reason, later). Gravel, pea size or what ever you can get (washed). Nylon screen, coffee filters. And a 591ml Plastic pop bottle (highest amount of crushing resistance).
Step 1) Make a dozen or more 1/8” or 3mm holes along the flat sides of bottle. Wrap one layer of screen around bottle, a layer of coffee filter and one more layer of screen (or nylon sock/hose). Bind with string or quick tie.
2) Put 1/2” or 1cm of gravel on bottom, put bottle in to figure where to make a hole for the neck of the bottle to protrude. Drill out hole, no larger than the pop bottle neck. Insert pop bottle from inside out, and put cap back on the bottle neck that is sticking out.
3) Cover bottle loosely with 1-2”/2.5-5cm of cleaned gravel. Cover all with screen. (water collection area)
4) Cover screen with coffer filters, and then 2-3” of charcoal, make level. Add screen again.
5) with sand, fill container to 2-3” or the length of your finger from the top .
6) drill hole in pop bottle cap to let the Filtered water out.
7) just add water, run two buckets through just to get the fine charcoal out of the system.
Your water should come out clean, the sand has bacteria on it that will Kill most biological’s going through it. When in doubt, boil or sanitize. If you find that the bottle caves in, you can tightly fill bottle with clean (boiled) pea gravel or Glass marbles.
When the water starts coming through cloudy, change your charcoal, OR, use a multi bucket system, one just for the Charcoal.
The same method can be used with a water barrel and perforated plastic water pipes in the bottom for greater water flow. Use you imagination. For more info Google it.

How to make activated charcoal for water filtering.
Use untreated charcoal, or make your own with seasoned non treated or painted wood.
Crush charcoal to granular size, to reduce dust spray with water. Put charcoal into a large container and add a mixture of 25% Calcium Chloride or Zinc Chloride, with 75% water. Or a 1 and 3 mixture.
Let stand for 24 hrs, and then drain on a screen for an hour. Rinse thoroughly with water, and put in a 220 F degree oven for 2-3 hours until thoroughly dry. Store in an airtight jar or a Ziploc bag until needed.
Not calling anything posted down but this is what I have, http://www.doulton.ca/cs0700.html Two candles mounted in the bottom of a 16 liter square food grade bucket that drips the gravity feed purified water into a second 16L bucket (8 gallons per day) that has a brass spigot mounted near the bottom. I pre-filter with a coffee filter. Providing the water isn't chemically polluted it should be potable. Perhaps not the best tasting but still potable. This all breaks down and stacks into about 20L (4 US gallons) of space and weighs less than 10 lbs total. I'll take some pics and edit this post in the future. BTW my total cost is about $160 CDN & a couple of hours of time.

Hey Radar,
it is always good to have options, thanks for posting this.
