Small Katadyns are perfect for soloists, but a proper pain in the backside if you need to pump water for dinner for a crew of six.Īnyway, in 1996 while traveling in the pacific northwest I got into some tannin laden streams that caused frequent clogging of my Waterworks for the first time since I owned it. I had a Waterworks since 1994-ish (possibly 1995) and loved it for it's capacity to really crank out a large volume of water in a short period of time when I was still doing the wilderness trail crew thing. Less if you are in silter or dirty water.Ĭurrently I use what I think is the equivelent to the MSR Miniworks. The MSR will filter 750 Liters of clear water before you have to change filters. There are some filters on the market that either have a small enough pore size or add an iodine chamber to kill viruses but most don't. You still need to chemically treat the water for viruses if you are in an area that is prone to industrial or agricultural runoff. I've seen a lot of folks make that mistake.Īlso, remember that most filters don't kill viruses.

If you package both tubes up together then any giardia, etc that might have been on the inflow tube can cross contaminate the clean water tube and you can still get sick. I package mine in a zip lock bag by itself. You want the clean water tube to stay clean. Whatever you get make CERTAIN you keep the inflow tube and the outflow tube separated when not using it. If you look around you can get it for around $70 or less if you catch it on sale. 1.25 liters a minute is what they advertise and that's about right.in clear water. It's quick and easy to use and pumps a lot of water in a short amount of time. The filter is super easy to clean in the field if you have to clean it. Mine also came with a 1 liter bag but I don't think the new ones do. It comes with the pump, an adapter cap to fit Nalgene or other bottles, Virus Guard to kill viruses and a filter cleaning brush. It delivers twice the amount of water in the same amount of time as a single stroke pump.
