Wonderful. I do have the bleach type sterilization tabs, so I guess I only need a filter. If water is suspect, just treat with the tabs after the filter eh? I went to the local camping store today (those guys are great) and learned that to provide daily drinking and cooking water for a family I would want a gravity flow system rather than a pump. The pump style they had would take 48 pumps for one quart! That would be 600 pumps for one family day in perfect weather and no activity-ack! Where the gravity flow one filters four quarts in 2.5 minutes.
Anyone have experience/knowledge of this one?http://www.platy.com/product_detail.aspx?ProdID=29
Excellent! glad we got on to this next idea! (I said I like talking filters) I have worked at REI for a long time so I know the camping products in and out, I spent alot of time talking to the reps from these companies and training people on this kind of gear, (I love this job lol).
Well I was hoping you would ask about gravity filters. If you want to treat water for a family, this is by FAR the best way to go, honestly! There are two brands I would check out, the brand Sawyer just came out with a system, and so did Platypus. When the Sawyer system came out I had the opportunity to be a product tester for it. It holds about 4 liters of water and claims to filter it all in about 3 minutes or so. Its nice cuz you just fill up the bag with the questionable water, hook it all up and let it go while you do your camp chores. We had one going for a group of three of us and it was perfect. I fell in love with gravity filters after this.
Now, there was a problem with a vacuum forming in the bag while it was filtering which would cause it to slow down dramatically, there are ways to fix it, but I found with the Sawyer filter you almost had to fix it every time, I found this counter productive because to me the point was to forget about it and let it do its job.
The brand Platypus fixed this, if you are worried about a vaccum forming, the top of the feeder bag opens up to let air in while it still filters out the bottom, it is also easier to fill this way. the Sawyer one was all out of one hole, so while it was filtering you could not open it up to let air in. kinda stunk.
the Platypus is also lighter in weight.
Another neat thing about these bags is that the filters never run out, they last forever, once it clogs you just backflush it until its clean again and you keep going, most are guaranteed for a million gallons or somthing crazy like that.
SO, yes, if you can afford it, go with a gravity filter since its not just for you.

I have not tested them all but it seems to me that the platypus one is the best buy. read the reviews, find out for yourself
I know that both REI and cabelas it would be guaranteed for life, so If you find something wrong with your choice you always have a fail safe.
Let me know if you have any other questions.
