I had this purifier for about 3 years now and used it on about 10 UK wild camping trips. It failed on the third trip and then again a few weeks ago. The recent failure led to me get dehydrated on one of the hottest days of the year until I took to drinking dirty water. I was on a remote wild camp and needed to pull water from a large pond / small lake high in the hills.
I'm an engineer and there's a flaw in the design people should be aware of. On both trips I was using it to do what it's designed for..... to clean, filter and purify water from a source that was mildly discolored and contained some sediment. Wayfarer claimed the filter cartridge was blocked and it was user error. Thing is i'd only taken a few litres from a mildly contaminated source. The design claims to be more than capable but it's failed twice in conditions which should have only pushed it to 50 or 60% of it's claimed ability. The design problem is that the filter cartridge implodes and bursts resulting in dirty water passing straight through the filter. So not only did it fail when up against a modest challenge it failed in a way which was unsafe. If the water was not dirty this failure could happen and you wouldn't know till you got sick. The design needs a pressure safety valve to protect the filter and prevent dirty water passing through.
The first time it failed, and with lot of effort on my part, wayfarer reluctantly replaced the cartridge when it burst in service. This time I'm not going to bother sending it back and having a battle with them to get good service and a device that works as advertised. I don't trust the design.
I see lots of good reviews.... but that has not been my experience
Well it looks nice and is now full of water. I’ll have to wait until after the zombie apocalypse to let you know if it purified the water enough so we didn’t die. If we still have the Internet and no body has stolen all of my solar panels so I still have power, I’ll be sure to update this review.
