Question: Where do I find directions on how to remove and replace the filter?
Document: This filter element is getting harder to find and I'm grateful to get this replacement. The entire filter is excellent with a high flow rate and very reliable function. I assume there is a suitable replacement on the market but I'd rather spend the $45 to replace the element than the $80 for the entire rig.
This is what I have been looking for...I am so glad that I can still find this cartridge for my Katadyn Guide water filter...works flawless...
I purchased this item as a replacement filter for my PUR Scout (now discontinued). The actual pump assembly has had very little use over the years, so I didn't want to replace the entire device. The Guide replacement filter functions perfectly. The enclosed mesh screen definitely helps prolong the life of the cartridge by pre-filtering some of the particulate. The instructions included were very easy to follow, and installing the new cartridge posed no problems.
If you have a Katadyne Guide or PUR Scout filter this replacement filter works. This was the best price I could find for the Katadyne guide replacement filter.
I have had this filter for several years and it has one giant flaw in that it clogs up very quickly regardless of how clean the water you are filtering is.....10-15 gallons of water and you can barely pump it....cleaning helps but pressure washing the filter is the only thing that really works...find a better filter if you want to do more than a nalgene of water every now and then!!!!!
Glad to be able to find a replacement for my filter cartridge. It works great and arrived on time. Thank you.
I've done a lot of backpacking over the years and had good luck with my water filter. Since it was getting old, it was difficult to find the replacement cartridge, but this trusty on-line retailer had a supply and solve my problem. The product works great as usual.
REI no longer carries a replacement cartridge for the Guide water filter, no longer manufactured by Katadyn. it's a very serviceable filter for camping; so I hope Amazon continues to carry it!
My wife and I were backpacking 400+ miles on the PCT and after one week this filter stopped pumping water.I sent the pump home and resorted to chlorine and other options.After the backpacking trip I returned home and checked out the Katadyn filter. All of my old filters worked just fine in this pump housing. I changed gaskets and lubed all that I could.
This filter seems to work well, but clogs more quickly than I'd expect. I have not used any other filters in recent years, so have no basis for comparison, but this filter seems to clog quickly when pumping seemingly clean water so that it gets hard to pump. This makes pumping a lot of work and slows it down. This filter belongs to our Scout Troop. I'll try a different filter when I buy one for myself.
Answer: yes
