Katadyn Combi Microfilter

Among the Katadyn water filters, the Katadyn Combi is our overall pick. The Combi Water Filter is comparable to the Katadyn Pocket filter yet it has an activated carbon stage in addition to the 0.2 micron ceramic element, and its pump rate is a bit faster (1.2 L per min vs 1 L per min for the Pocket). The carbon removes chemicals such as chlorine as well as bitter tastes and odors. Like the Pocket filter, the Combi water filter's ceramic element treats an amazing 13,000 gallons (if you choose to use the carbon granules, they should be replaced every 60 gallons - carbon stage can be removed when not needed to preserve its life). Katadyn constructed the Combi with extremely durable polymer, and it has a stainless steel pump mechanism. It includes two packets of activated carbon granulate and comes with a zip-up carry bag. Like all Katadyn water filters, the Combi Plus will remove all giardia, fungi, parasites, cholera, typhoid, cryptosporidia, salmonella and other harmful bacteria, parasites, and germs.

Bottom Line: Drink clean water on your next backpacking trip and avoid parasites and other nasty water bugs with the Katadyn Combi Water Filter.

how much does this bad boy weigh? Is it recommended for back

how much does this bad boy weigh? Is it recommended for backpacking?

This weighs 580 g (which is about 1 1/4 pounds). It would be excellent for backpacking, although it is a little on the heavy side.

Answer Josh's question >

I trust Katadyn

By: Backcountry Reviewer Squiggie
April 24, 2003

The only thing worse than drinking a contaminated glass of water on a trip, is finding out your mother-in-law happens to be staying at the same hotel. There are many items that you can cut costs on and get a cheaper, slightly less functional piece of gear. But with water filters, it’s not a bad night’s rest or a tear in a pack that a roll of duct tape can fix. Although if you get a virus in your water you may consider using duct tape so you can get out of the baño for 5 minutes. If you want to quench your thirst without worrying about side effects then get a Katadyn. I take this filter hiking. It's not the lightest but I like the peace of mind.

Does the filter remove viruses? Hepatitis can make you rather ill when travelling.

By: Cathy

No Katadyn microfilter will remove all viruses. There are no vaccines for Hepatitis E, Rotavirus, or Norovirus(Norwalk virus: which can occur in S. America, Africa, & Asia. Waterborne transmission can occur below fecal contamination from infected humans.
My recommend for travel where viruses might be in the water is to first microfilter, then add chemicals to the water. Microfiltering removes protozoan cysts, which the best chemicals (Katadyn Micropur) can still take up to four hours to kill. Microfiltering also removes bacteria, along with turbidity, and organic materials: which can interfere with chemical processes.
Per University of Arizona Dept of Microbiology testing Micropur will kill all viruses, even in dirty 38 degree F. water, within 15 minutes. Although you might notice a faint chlorine odor, there is no chlorine taste with Micropur tablet. Although Chlorine bleach or Iodine tablets will also kill viruses, there is both unpleasant taste and odor

No, it won't remove viruses. Make sure you're up on your shots.
