Best Use Backpacking
Rated 5 out of 5 by from The Bomb I am former river guide, back packer and mountain biking enthousiast... I have used this product for >10 years, on back packing trips ranging fom 30 to 300 miles, and always carrying it with me on other activities so I don't run out of water ever... the hiker is bomb proof... the only time I have seen someone get sick is when they did not take care to keep the intake and output separate... seriously prolong the filter life of this product by prefiltering with the tip of a paint strainer tied around the intake with a hair bungee (get from local paint or hardware store)... enjoy!

Rated 4 out of 5 by from good for 5days We used this to filter water while at Northern Tier in Canada. The clarity of the lake water was 12 feet. It worked well with good flow for the first three days, and on the fourth day, the flow rate dropped noticeably. on the fifth day it was just dripping. We were careful to get the cleanest water from the center of the lake and I tried to rinse the filter after every other day. I would use this again, but would look to see if there is any other way to extend the filter life. We only filtered about five gallons per day. I would recommend this to a friend with the warning about the limited life issue

Rated 5 out of 5 by from Katadyn - Katadyn Hiker PRO Element I purchase this as a back up filter I will be carrying in my backpack when I start my thru-hike of the A.T. on February 16, 2015. I am still using a Pur Hiker. The Katadyn Hiker PRO Element works in my old Pur Hiker. It's a great product that I have used for almost twenty years.

Rated 5 out of 5 by from Manufacture Warnings are Correct A warning from manufacture states, not designed to clean dirty water! Filling one waterbottle full was all she wrote on the Escalante River. Manufacture suggests to use a hankerchief around inlet filter, to further filter the talcum-powder silt. Even letting the water "sit" for a couple of hours before filtering is better, but not great. Great filter though, just be careful and wise with silty water.

Rated 5 out of 5 by from Easy Replacement The Katadyn Pro filters are easily replaced and last a long time. I have used this filter on very long hikes and backpacking trips in Pennsylvania, New York, Utah, Wyoming, California and Hawaii. Never got sick, so I would say it works. Make sure you follow the cleaning procedure after each trip and this filter will last a long time.

Rated 4 out of 5 by from Hiking NM Use this with Hiker2 Pro. I was in NM CDT and very dry. Needed H2O and a cattle tank was available but very dirty/algae/cattle poop. Used the filter plus a hanky. I look/smell the result and it seem fine...use the H2O for bottle and Camelback. It did get very hard to pump but expected that. Did also put iodine pill in the H2O...just in case.

Is this the newer 0.2 micron filter or the older 0.3 micron filter the Hiker Pro came with... Katadyn's and REI show new Hiker Pro models have  0.2 micron filter, but mine came with a 0.3 micron filter. Neither site shows the pore size this replacement.

Asked by: matlikeadoor
The Katadyn Hiker PRO Element we have in stock has the updated 0.2 micron filter.

Will this filter fit my old PUR Scout water filter. Wish to keep the scout as it has been good to me. Replacement Filter was 15026.

Asked by: rce
The replacement filter you will need for your PUR Scout Filter is the Katadyn Guide Pro Element. Unfortunately we do not currently have the Guide Pro in stock. The Hiker PRO Element is not compatible with your PUR Scout.
