Katadyn Hiker/Hiker PRO/Base Camp Replacement Element

REVIEW/REPLACEMENT WALKTHROUGH: A simple, easy to replace cartridge. With replacement, this will upgrade your Hiker model to the Hiker Pro! Added field serviceable filter protector extends filter life in murky conditions. 4 stars only because I think the replacement element is pretty expensive.

Servicing my 20-year-old PUR Hiker this weekend, I decided to post a walkthrough of the filter cartridge replacement. This kit will maintain all PUR and Katadyn Hiker/Hiker PRO models. This model of element has been readily available for a long time, and I think it will continue to be. The replacement specification of the cartridge is every 300 gallons/1135 liters. It is also recommended to disassemble the filter after use to dry all parts out in order to prevent mold & bacteria growth. 

There are two main differences betwixt the Katadyn Hiker and Hiker PRO. One is the quick-connect for easily filling water reservoirs. The other is a removable filter protector. With the exception of the quick connect, buying a replacement filter will make your standard Hiker model now a Hiker PRO. I initially doubted the effectiveness of this protector, but after installation I think this will help a lot of users from shortening the lifespan of the element.

Even with proper care, these cartridges can get pretty nasty... The blue cartridge on the left probably only had filtered about 100 gallons.

Inside the box, you will also find a small tube of silicone grease to treat the o-ring. Without doing so, these filters become very stubborn. There is also a (quite nice) sponge for servicing the removable filter protector. 

The protector feels like a textured piece of vinyl that has very small pores. The kit also comes with an additional plastic net to secure the filter protector.

Here is an image of the new cartridge without the removable filter protector.

And with the protector.

It is also very important to clean and dry the inner housing of the filter itself. I have found it common to find little bits of silt and crud to remove. I also find it helpful to add more silicon grease to the threads. 

I personally like to put a service date on the filter.

And here is my ~20 year old PUR Hiker, ready to go for another round!

I hope this review is helpful to everyone, thank you for your time!
