Water Safety Equipment

I have not used it, so I am not sure, sorry. I purchased it to add to my prep supplies. Thank you for asking.

I bought this 2- 3 years ago for use on scout backpacking trips and emergency use during hurricane season. The thought was to have zero worries with water supply no matter where I was. The troop had another MSR filter with lower filtration pumping 1L per minute. Scouts became impatient and those were quickly abandoned to use mine. Win# 1! We recently took a long distance backpacking trip and most groups used micropur tablets for sterilization, but not wanting to wait used this filter instead for immediate water consumption without an altered taste. Water supplies were typically streams or in some cases cisterns from rain collection or pumps which still needed sterilization. Win# 2! One camp ran out of water in their cistern with zero streams for decent water nearby. I said not a problem and we filtered out of a cattle pond full of all kinds of bugs, algae and things no one wanted to deal with. This pump had zero issues and no one got sick. Win# 3! Lessons learned: most of the time, filtration just occurred over one or two days, this last trip was longer. If the nalgene was too tight, it would cause leaks between the filter and the water bottle. The same occurred if the gray ring at the bottom was too tight to the red cylinder on the filter. Loosening those connections brought everything into alignment with no leaks. A gentle tightening was all that was needed. After each trip, I do pump some clean water through the filter thinking one or 2 extra liters wo n't impact the life of the filter. I hang the filter to dry out the entire length of hose, and invert the filter section with fibers so it drains as well. I 've had zero issues with the performance of this filter and have full confidence whenever it is used. I still carry the maintenance kit with me, but it has yet to be used.

WE have been using the Guardian Purifier for several years now and just purchased out third one. We use it in a wilderness camp for up to 9 people for two weeks duration. We have never had a problem with the device or supplying ample water for each group. Several of our guests have purchased on for their own use after using the Guardian in our camp.

Used this filter on a backpacking trip recently with 5 other people. I used a less expensive MSR filter previously that worked great but had to be cleaned frequently or it would screech to a halt. The Guardian had no problem filtering multiple Nalgenes all day for 6 people. Do n't over- tighten your bottles on to the filter! This is the main issue I see people having, and I understand the temptation. I had the leaky piston and base issue but once I backed off the tightness everything was great.

Love the peace of mind! Easy to use& fills bottles quickly. We wanted one filter that we could use on any trip no matter where in the world, and no back- flushing makes this a dream.
