The MSR TrailShot Pocket-Sized Water Filter for Hiking, Camping, Travel, and Emergency Preparedness is designed specifically for adventurers who want an effective, reliable water filter without the weight. Ultralight at just five ounces, and measuring 6x2.4 inches, it fits easily in a stash pocket when backpacking, hiking, trail running, and mountain biking. And when it’s not on the trail, it’s on hand to provide clean water during disasters and emergencies, and in survival situations.

  • lightweight and convenient
I have a guardian and a sawyer squeeze system as well as steripens and aqua mira. This is my new goto filter for wilderness areas where I don't anticipate high human impact and therefore viruses. Some have complained the filter clogs quickly and pumps slowly--I have found the *pre filter* can indeed clog easily if you're not careful. I've discovered that it's usually organic material in a shallow stream. Before I filter, I will stomp and disturb the gravel in the stream bed first--this turns it very brown and murky for a second, but flushes away organic material and makes the prefilter less likely to clog. If I have a hand free, I will also keep my thumb at the intake filter and wipe it between squeezes. This, combined with keeping the intake screen facing downstream eliminates a lot of issues. I've been vigorously shaking it every 5-6L to backflush and have experienced standard 60second/L pumping times. Others also complain that it stops working after drying out--MSR says not to let the filter completely dry out, and if it does, pre-soak it to restore flow. This is not as convenient as the guardian, but only 1/4 the weight, and still way more convenient than a sawyer squeeze at approximately the weight. ... show more

  • This filter it's not a purifier.
I love the simplicity of the system. However it is not a water purifying system. Do not confuse this system with other systems that not only filter the water , they also make it safe to drink from almost any source of water. It is great to have water for cooking or collecting clean water for purifying. It will not protect you from viruses causing illness. Don't get me wrong , it is a great tool to have when you need to collect large amounts of water. ... show more

  • Lightweight water filter
I'm a long-time owner of an MSR MiniWorks. I left it at a family's house and needed something for a backpacking trip. Saw this and gave it a shot. FILTRATION: It works well, I'm filtering at least a liter per minute with it. My hand got a bit tired after filling a 3L reservoir and a Nalgene 1L all in one go, but switching hands ameliorated that. You can filter some pretty nasty water and it comes out perfect. There's a small coarse filter at the inlet of the line, and then you pump the water through the microfiber filter. It gets >>99% of bacteria and protozoa, and it even deals with most viruses unlike the ceramic filters. Only downside is that it won't filter chemicals at all unlike the ceramics, so areas with a lot of pesticides or the like may be less suited. For the developing world with a lot of human waste, this is the way to go for the virus coverage. The taste is neutral; I didn't notice any plastic-y hints at all. It also allows you to use it like a LifeStraw which is a feature I enjoyed, and while a Sawyer Mini would allow you to pre-filter a reservoir, it would require multiple fills of the dirty water bag and this can be run continuously. STORAGE: I keep it in one of my hip belts on my pack which provides for easy access. It took seconds to pull out and put away. The only downside I identified: the soft rubber tube is a bit fragile as evidenced by a few small nicks after my first trip with it, nothing that compromised the inner lumen. I'll be getting a soft mesh bag to protect it since it doesn't come with one. CLEANING: There's almost nothing to do in the field. They recommend taking off the inlet hose and back-pumping once per six liters filtered to keep the pump reservoir clear of debris buildup; I did this every other time I used the filter. It's nice to not have to wipe off the filter periodically like you have to with the ceramic cartridge based filters. STORAGE: The device is easy to take apart. I run clean water through it, disassemble, and let everything dry out before storing. The manufacturer recommends running diluted bleach to sterilize everything between use and long-term storage. OVERALL: I'm impressed by this device and glad I made the purchase. As long as it lasts, it'll probably replace my old MiniWorks due to the smaller size/weight, ease of use, comparable filtration rate, and added virus coverage. ... show more

  • Handy and small
Perfect size for a overnighted or day hike. Easy to use although at first my hand was tired after filling half a Nalgene, easier now that I’ve used it more.

  • Think of this as a portable drinking fountain (if you're old enough to know what that is)
I was originally drawn to the size and relative light weight of this water filter. It would be replacing a Katadyn Hiker Pro. HOWEVER, it has a very low flow rate. And, it takes a long time to filter any meaningful volume of water. A lot of effort for not a lot of filtered water. Like a good forearm strength trainer for weightlifting, this thing gives your forearms a good workout. A mod I made was to purchase some tubing the same size and replace the input tube with a length of about 3 feet to make it easier to reach water sources. This fairly easily gives you a drink of water like a water fountain would. But, if like me, you naively hope to fill a water bladder, or if you want to drink a 1/4-1/2 a liter or 8-16 oz of water at once, this might not be the most effective filter for that purpose. ... show more
