MSR TrailShot Microfilter Water Purifier

La conception avec un tuyau déporté et une « poire » est très pratique : cela permet de ne pas utiliser de récipient intermédiaire et de prendre même dans un petit filet d'eau à une source. Le débit est élevé : en une minute environ on remplit sa gourde. Seul petit point délicat : le rinçage et séchage pour le stockage longue durée. Mais c'est le cas pour tous les filtres.

Muy poco voluminoso, fácil de usar. Perfecto para las salidas al monte

手軽に安全な水が手に入ります

Usato in montagna per filtrare acqua da bere prelevata da un laghetto.... Prodotto affidabile!

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.
