Pre-Filter

Have you used this setup long enough to clog a filter yet? I'm especially curious about how well the modified lever works when cleaning time approaches.

This is why I decided to get the MSR Sweetwater Siltstopper Pre-filter for the Hiker Pro and add an ounce. When the pre-filter gets clogged it's just a matter of turning it around on the line and back flushing it. I hate pumping when the filter begins to clog.

Great thread folks. A new water filter is on my list of soon to be acquired items so this is VERY timely for me. Can't wait to read the upcoming evaluations Reality.

Thanks so much.

Reality, thanks for the info. Are you treating the water first and then filtering it? that system appeals to me but it does require a bottle for treating the water. And then I assume you have to pump the water from the treated bottle into the hydration blatter through the bladder. If so, what bottle or other vessel are you using for the pre-treatment?

You are quite welcome, nogods.

I just used my modified Sweetwater filter again today. Works great.

There are several options, two that I've used are containers found in the Wash (Sink) Basin thread (i.e. Bowl Buddies Fold-a-Bowl and the Backpacker's Bowl). [I've provided some weight and specs for those options in the aforementioned thread.]

I use a 4L Platypus with the ziplock top. It's advertised at 2 oz, and folds up to very thin when not in use. I fill the Platy with untreated water, drop in 4 Micropur tabs, wait, then use the filter to pump into pot, bottle, and bladder. Works GREAT. Water has no chem flavor.

Reality, thanks for the great ideas in this thread. It wouldn't have occurred to me to remove the handle. I'm glad you shared it because on my last trip out (after I don't know how many years of service), the handle connection broke on me and the handle fell off! At first, I thought it was a catastrophic failure and I was out of a filter for the rest of the trip. Then I remembered reading this thread and realized it wasn't a catastrophic failure after all. I just continued using the filter. I miss the extra leverage, but it does pack much smaller now. Don't konw if I'll spring the $80 just to replace the handle...

I just got back from an overnighter, where I used the filter sans handle as per above. I missed the handle. It was easy enough to push the pump down, but not so easy to pull it up. That is, untill I thought to put a paracord wrist loop where the handle used to attach to the pump. Now, the wrist loop helps on the up stroke, and the filter is very easy to use with only a minimal addition to weight.

GGervin, the wrist strap is a good idea for those who would have any trouble without it. My guess is that many will appreciate it, because a significant number of people do not like to pump water even with a handle. So, IMO, your idea will help many of those who actually use this mod.

Thanks for sharing your actual experience. If I were with you when your filter lever broke, I could have said "that filter's not broke, that's just a modified lightweight filter."

I've added another water treatment option in this series: Sawyer Mini & Aquamira Frontier Pro Water Filter Mod / Combination.
