Rated 5 out of 5 by from Super easy to carry and use! I thought it would be hard to pump into my water bottle, but it was very easy and quick.

Rated 5 out of 5 by from Prevent cross contamination! Since this was announced at Outdoor Retailer I have had my eye one it. I have been more than happy since I got one! This compared to the Sawyer Mini and Lifestraw, to me there's no competition. It's convienent and the risk of cross contamination is much lower since it has a hose to keep contaminated and clean separate!

Rated 5 out of 5 by from Great piece of gear! It is compact, light weight and very easy to use. I like redundency on important items in my kit so I'm glad to add it to my arsenal of gear.

Rated 5 out of 5 by from Simple and easy This, quite simply is the easiest, quickest way to filter water that I've ever used. Being an MSR product, I have complete confidence in it's effectiveness...

Rated 5 out of 5 by from So far, so great Got this last month, and have used it once in the backcountry. Super awesome so far..pumps pretty fast (albeit with a little pump in the hands and forearms), super packable, and most importantly...its super light weight. Quite a lovely purchase.

Rated 5 out of 5 by from Lightweight, reliable, and super easy to use! I've been avoiding buying a water filter for years by bumming H2O from my pals when we've been out in the bush. Finally, when taking a trip to Seattle to climb Mt. Rainier and do some backpacking in Rainier Nation Park, I decided to pony up the bones to finally get one of my own. Being the uber frugal gent that I am, I embarked on my search for the lowest cost yet reliable option; enter the MSR Trailshot. This thing was awesome! It filtered the glorious mountain stream hydration catalyst to utmost perfection; find a clean-ish looking spot with some rock filters, insert tube, pump away and you've got a steady flow of high quality H2O for you and your comrades. The filter lasts forever with their hollow fiber tech and is low maintenance (read - easy to clean). You will develop some serious Popeye forearms pumping this baby given the manual hand motion required. I look forward to using this little guy all over the world!

Rated 4 out of 5 by from Filters hotel water and river water perfectly Used this filter in the Porcupine Mountains in northern Michigan. Quick and easy to take out of your pack, fills up my 2-liter bladder in just a few minutes. Not sure I believe in the claimed speed but still easier than my MSR Mini Works filter that screws into a bottle. The Mini Works is a bit faster but then you have to either transfer the water from the bottle to the bladder or hope you don't spill. Doesn't seem to filter out taste from water as well as the Mini Works. This was somewhat concerning in Michigan's UP - the hard water is wrought with iron and copper - but I didn't get sick. I could still taste some traces of iron in the water and it has a slight orange tinge.

How do you know when the filter has reached its maximum cleaning capacity to operate at full functionality? Also, can you/should you backwash the filter?

Asked by: Dean
Hey Dean, Thanks for the question. You can backwash this by shaking it! As for checking the filter, MSR recommends doing the following steps to check it's functionality: 1. Hold the filter at about 45° and prime it by squeezing the Bulb (G)10 times. 2. Pump 3/4 liter of water into a bowl or pot. 3. Unsnap the Prefilter (M) from the Female Check Valve Housing (L) (put it in a safe spot). 4. Unscrew the Female Check Valve Housing from the Male Check Valve Housing (J). 5. Remove the Check Valve (K) and reverse its direction. Place it back into the Female Check Valve Housing. 6. Screw the Female Check Valve Housing back onto the Male Check Valve Housing. 7. Remove the Spout (B) and Umbrella Valve (C). 8. Place the Cap (D) into the bowl/pot of clean water and pump 1/2 liter of clean water backward through filter. 9. While the Cap is still submerged, squeeze and hold the Bulb. Then remove the Cap from the water and release the Bulb. 10. If Bulb re-inflates within 30 seconds, the filter is NOT SAFE. (NOTE: If a few bubbles escape the Check Valve, unscrew the Female Check Valve Housing, reseat the Check Valve, and screw the Female Check Valve Housing back onto the Male.) Then test the filter again. 11. If Bulb stays compressed, the filter is safe to use.

How to store for the season?

Asked by: Seabreeze
Thanks for the question! Below are the pack & storage instructions for your filter. I also included a link to the manual. Hope this helps! 1. Remove Prefilter from water. 2. Squeeze Bulb to purge excess water. 3. Replace Clean Side Cover. 4. Before long-term storage, remove Filter Cartridge (See “Replacing the Filter Cartridge”) and let Bulb and Filter Cartridge dry out at room temperature for at least one week. 5

It is "field cleanable to restore flow" - but does the filter ever need to be changed? If yes, how much are they?

Asked by: Dave
Hi there Dave! The MSR Trailshot's filter does need to be changed after filtering 2000 liters of water. We do carry the replacement filters: Happy hydration!
