rated 5 of 5 stars Great device. I have a few Combis. Used one with mountain water in Auburn, California, and didn't have a problem.  In fact, the water tasted amazing. Full review

Base Camp

rated 5 of 5 stars Excellent filter for floating rivers in Alaska. I've been using the Katadyn Base Camp gravity filter for almost 20 years in Alaska. It works great as long as the water source is near camp...floating rivers or backpacking near alpine streams.   Since it is a gravity system, above timberline I set it up in the rocks on a steep slope and stretch the outlet line as much as possible downhill to maximize the flow rate. I clean the filter after each trip by removing the prefilter screen, soaking in soapy… Full review

Vario Microfilter

rated 3.5 of 5 stars Great for group trips. This is a big monster of a pump that is great for pumping super clean water fast.   Effectiveness I've always used the pump in the long life setting which involves both filter functions, the ceramic disk prefilter and the pleated glassfiber filter. The faster flow setting disengages the ceramic prefilter. The pump also has a carbon filter to make the water taste better, which is one of my favorite features. Neither myself or anyone who has used the filter has ever been sick. Full review

Hiker PRO

rated 3.5 of 5 stars Works well; pump plunger broke after many uses, but Katadyn replaced it. I've gotten a lot of use from my Katadyn Hiker Pro water filter. I used in on a series of 3- to 5-day hikes, and I also used it on a daily basis when I was living for two months in an area where the water supply wasn't safe. Its design is ingenious, and it packs up compactly into a zipper pouch. The only flaw is that the pump plunger — actually, the flat "knob" at the end of the plunger — broke. (See photos below.) Perhaps… Full review
