Rated 4 out of 5 by from Fast and Easy I purchased this for times when I want something fast for an approach and the like. This really fits the bill. I don't have to carry an extra liter, just a couple squeezes of the hand and I have what I need. This thing is great!

Rated 5 out of 5 by from Ease of use I used my TrailShot on Washington Trail Association work parties for several months but lost it somehow last weekend working in the Methow Valley but I'll purchase another TrailShot shortly. What I like most about it is the ability to carry less water and keep refilling my water bottles as needed on trail work parties. Have enough weight to carry without a heavier filter or lots of water bottles. It takes up little room so it goes with me whether I think I'll need it or not.

Rated 5 out of 5 by from Coment on ULDude's review The filter portion of the Trailshot weights 1.5oz. The Sawyer Mini filter alone is 1.6oz and longer/wider. Yes it cost double but the Sawyer but includes a pump, pre-filter, and hose. I have used both and will now carry the Trailshot. KM

Rated 5 out of 5 by from Great wilderness filter Used the Trailshot on a recent trip in Maine's 100 Mile Wilderness. I'm always looking for gear that's light and compact, so I gave this filter a try. I was initially concerned that the short intake hose would make some filtering situations more awkward. But I discovered that the short hose actually makes it easier to keep the pre-filter steady, so that along with the minimal squeeze pump action (in contrast to two handed pumps), I was far less likely to stir up sediment in my water source. In addition, the feature that allows a direct hook up to my Camelbak is really great. Makes a closed system that eliminates having to juggle the pump and a water bottle. Just be sure you have the bladder and hose lined up, with no kinks or constrictions--otherwise, the pumping pressure will pop the cap off the Trailshot.

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.

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: https://www.moosejaw.com/moosejaw/shop/product_MSR-TrailShot-Replacement-Filter-Cartridge_10334738_10208_10000001_-1_ Happy hydration!
