Product Reviews
Rated 3 out of 5 by from Trail shot MSR only used it a handful of times last summer. Used it last night on a bike packing trip and seemed to be clogged and very slow flow. I like the compact size for bike packing but I had a hard time using it efficiently on my trip ! I took care of it well but didn’t last.

Rated 4 out of 5 by from Works well for a quick Works well for a quick filter on the go. As far as filtering multiple bottles worth of water, it would be kind of annoying but doable. Very simple, easy and light.
Date published: 2022-07-13
Rated 2 out of 5 by from Easily Clogged I have only filtered approximately 2 liters of water through my trailshot. 1 liter was tap water just to test it's function. The other liter was from water that had virtually no sediment in it. It worked fairly well for these instances. I then stored the filter for about a year, and when I tried to use it again it had no flow. I flushed it as per the owner's manual 5 or 6 times but the flow rate would not restore, as advertised. And the cost to replace the filter did not match the performance I was given. Overall, I would not rely on this filter, especially in the backcountry. I have used katadyn filters and they worked very well, I will likely continue using them.

Rated 2 out of 5 by from My Trail Shot clogged after little use in clean water. I guess I have the same complaint as so many of the other reviews. When it works, it is wonderful. But mine has about 1/3 of the original flow after very little use under relatively optimal conditions. I wonder if you could advise me on maintenance, how to back flush, etc. Would freezing cause clogging?

Rated 5 out of 5 by from Satisfied Used on one hike, works well so far. Vey comfortable to use (you don't have to float rubber bottles empty-handedly in cold stream water at -6C like with other filters). I hope it will last.

Rated 1 out of 5 by from Worked well for one trip. Didn't store. I used this for a five day backcountry hike and loved it. Filtering clean water. Stored it exactly as directed and mistakenly took it out for another trip without testing it. Good thing I had a back-up, because there was zero flow. Not sure what happened - I followed all directions to a T. Disappointed, as I did like it for the five days it worked. Light, compact. Replacement filters are not economical for such a short life. Unreliable.

Rated 4 out of 5 by from Suggestions I bought this cuz it's light and compact. On my third time using it, the body kept popping off the red filter sleeve, causing water to squirt out when pumping...with nothing making it through the filter. Fortunately I had a small zap strap to secure the body to the inner filter and got it working. I suggest MSR consider such a design improvement. Also, I wish it came with a bag. Once out of the package, it's apt to get damaged or dirty kicking around in my pack. A small stash bag would be an awesome feature. Other than that, good value for money.

Rated 5 out of 5 by from MY LIL HIKIN BUDDY I purchased my trailshot in 2019. I've hiked over 300 miles and i use it in the streams, creeks, and lakes. I fill up my hydro flask, soak my froggie cool towel with it, clean my face with it, etc. I've never had 1 problem at all. I take care of my stuff. I'm not hard on the equipment I hike and camp with. You take care of most things and they will last. Great product MSR.

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 https://d1l67pfsx3wblg.cloudfront.net/pdf/TrailShot%20Web_Instructions%20EN.pdf

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!
