Two of them Broke in the Same Place
My spouse and I each bought one. First the female connectors broke, then, after upgrading the connector, the MSR male piece broke on the filter itself. These might be worth it if one doesn't need to cinch their pack down at all. With Osprey bladders - we connected across the top first (but the filter will not fit as it lays perpendicular), then cut hose and connected lower & parallel to the bladder, but the pressure from cinching our Dyna & Duro running vests must have been too much for the MSR filter. We were left high and dry 4 times!
Works great
I use this filter in conjunction with an older MSR Autoflow reservoir (the red one with little clear window in the front) and usually filter into either 1L Smart Water bottles or cooking pots. I get good flow and great tasting water. I have used it up 10 days straight without any problems. Be use to get all the water out of the tube connecting the reservoir and the filter as well as the filter itself for the best flow rate. Back flushing is a breeze. Be sure to not let it freeze. I put in my sleeping with me if think its going to drop below freezing.
Seems to work!
I took this on a 10 day trip to Colorado and didn’t have any...explosive issues at all! I filled the bladder straight from the lakes and streams and had no issues physically so I guess it works. It would be nice to have a little more flow but to be honest it was probably the altitude that made it feel harder.
Easy to use
So I bought this really for comparison purposes with my Sawyer. I used it recently on a Catskill multi-day trip along with an Osprey 3L bladder and there is little difference with the Sawyer. I used it twice, at Dutcher Notch and again at Batavia Kill...filtering about 8 liters total. Worked well. I am still standing!
Excellent option if you carry a bladder…..
IMO Probably the best way to filter water if you carry a bladder system. Flow rate and ease of use is great. I have had no durability issues- so far so good. Hand Pumps are a pain to use and I’m not a big fan of chemical treatment. A bit tricky while carrying a bear canister - but doable.
Included directions suck
If you purchase this item, watch a video online to figure it out, as the directions that come with the product suck. I really haven't tried it that long as i made the mistake of buying this a day before heading out on a through hike. So i carried it and figured it out when i got home.
MSR Thru-Link In-Line Microfilter
it allows me to easily use stream flowing water when out hiking in the mountains close by where i live
Both Broke and Left Us in Danger
My girlfriend and I each got one of these. They broke in more than one place leaving us stranded 23 miles from safety. Thru-Links seem great in theory, until put to practical use: They are intended to clip in-line, but if you use an Osprey bladder the hose connector is at the top. Positioning the Thru-Link at the top causes strain on the device as the hose comes straight up and the filter would need to stick vertically out the top of the bag or have an elbow piece as a connector allowing it to be positioned horizontally. One can quickly deduce the hoses will need to be altered. Option #2 is installing vertically by clipping the hose near where it exits the bag. This seemed logical as it was to be used in a running vest and would be supported and cushioned by the water in the bladder on one side and the stretchy mesh of the the vest. Trip one: 7 miles into a 50k I feel my back get drenched. The MSR brand female connector has broken just below the filter. With no spare pieces and a contaminated bladder we were forced to run the remaining 23 miles on a shared bladder. (I did bring a Squeeze Mini and guzzled from it on each water stop) It was evident the MSR connectors were junk. I replaced with a spare Osprey connector and added a slightly longer hose to give it a little more flex and relieve some tension. Trip two: Her MSR female connector broke spilling water all over her back. My MSR Thru-Link filter housing broke on the male end that was plugged into the Osprey female connector spilling water all over me. The plan was to save time, instead we wasted hours and were dehydrated on 95° summer days. I would consider the MSR Thru-Link to be a danger and would advise against relying on one. Pros: Scoop and go Flow rate is not bad Bottom Line: MSR really needs a stronger polymer to make this work.
Broke After 4 Uses
I was loving this filter until the plastic randomly snapped after using it 4 times. The plastic where it connects to the water bladder broke during my run the other day, causing all my water to rapidly leak out of the bladder. This is not a well-made product.
Great filter
I've been using this filter for a year now, really happy with it. I use it both as an inline-filter when attached to my dirty waterbag, as as a gravity-filter to my clean water drinking bladder that is inside my pack. The only downside for me is its "lenght" at 19.5cm I've had difficulties finding a "small, but large enough" pouch to keep it "clean" from dirt and "not leaking into my pack" inside my backpack when not in use.
