I’ve heard it all before and will 20/20 hindsight, I probably should have tested it but why would I suspect any problem? I used it once in clear water to filter a couple of liters of water at the most. In my mind, it
was a new filter and should have functioned just like it did the first time. If I had used it for many gallons of water, I might have suspected something or thought it needed a back flush but it had only been lightly used.
As for carrying a spare, again, why would I suspect that I would need to? I have carried ceramic filters and never had to think about testing them before I took them on a trip. If they worked before, they would work again. I look at the element before I store them and replace it if needed...only had to do that once. A spare one is another $40 as well.
My point is a cautionary tale for people who are considering the Sawyer. If you buy one, most certainly test it before you use it, especially if it has been stored for an extended period. Since mine failed I have seen other people reporting the same thing. But, as with my experience, they only discovered the problem when they needed the filter to function.
