Some other filters you have to run the water through a sock or something first to get the dirt out of it, if there's any in it you can see. It's not as necessary or time consuming with this filter.
These are easy to change, and it's always good to have a spare filter for when your original one dies. The Ready Store has awesome customer service. I've made 2 separate orders, and I will definitely continue shopping here. Everyone on the phone and their online chat service is very friendly and professional. If they don't know the answer, they find someone who does and give you the info you need fast!
I ordered a replacement filter for my Katadyn hiker pro. it gives me an easy feeling knowing I've got a back-up filter just in case...
