Review: Great product, i have been testing it out over ... - Great product, i have been testing it out over the last few days and the result is always the same, good tasting clean water no matter the water source and FAST. I read many reviews on water filters before purchasing one and this one was at the top of most list's and noted its down side was the size of the device upon receiving the guardian i would have to disagree the size is comparable to most systems and simple as could be for use. I will be taking it into the field on Friday for a week long backpack trip and after that i will comment more about the durability of the unit. As of now i am pleased with the quality it seams well built and easy to maintain and can be taken apart and serviced in no time if need be. It also came with a nice zip up carry case. I would say its well worth the money and will probably last me forever. Returned home from the trip, after a good field test I would go with 4.5 starts but will leave it a five. Wear the pump handle attaches to the plunger is a mixture of steel and plastic parts it held up fine but it is all held together with a plastic C clip, if you get much more than a moderate pump pace the clip hangs up and pops loud, I am certain this clip will fail and break at some point so i plan on finding a spare. The clip is basic something you would find at a auto parts store for cents and will be metal :) the other thing i noticed in the promotion video for the pump it says as long as the filter on the end is wet it it will pump only water and no air....that is mostly true but on 2 occasions it pulled air and we were forced to hold it under water and it primed up and was fine. Other then the clip it pumps and cleans water very fast and efficient its quiet and easy to set up and put away i would buy it again.
Review: Comes in a nice zip up case with a fine mesh screen on ... - I picked this up to have access to clean water for a group while backpacking/traveling or for emergency conditions where public water is contaminated. Think of boil water advisories when the local water main has broken. Remember this is a mechanical filter and that chemical or radiological contaminants are NOT removed by mechanical filters. This won't help you fix the water in Flint, MI or magically turn seawater into potable water. Eager to see how this works, I ran a little test with a water source I know is contaminated with coliform bateria. I took samples from the source and from the water filtered by this unit. Running the samples and a control through a test kit showed the filtered water was indeed bacteria free. Ultralight backpackers will balk at the weight but for me I appreciate the ease of use. I was surprised a how fast the filtered water comes out. Fits my Nalgene bottle perfectly. I don't have to mess with bags or wait around for gravity to work. Hose is long enough so you don't fall in the pond or river trying to scoop up water. Comes in a nice zip up case with a fine mesh screen on top so when you put it away the hose can dry off with out contaminating the rest of your stuff. Be sure to buy the annual maintenance kit which is sold separately - it contains o rings and other goodies to maintain your pump I like that this filters viruses. I wish I had had this on recent trips to India and the DR. Now I am better prepared! I also appreciate the fact that it backflushes itself on every stroke. Very clever. This thing is pretty expensive but it is so easy to use I am glad to have it.

### ⭐⭐⭐⭐⭐ Best purchase I've ever made for backpacking and hiking
*by C***R on August 3, 2018*

This is by far the best purchase I've made out of all of the purchases I've made in buying adventure gear at places like REI, Cabelas, and Amazon. I've taken the Guardian on all of my backpacking trips for the past 2 summers. I also regularly take it car camping, hiking, canoeing, fishing, etc. This is one of my top 5 favorite adventure gear items that I own and take it every where I go. I don't know what I would do without it. I plan on taking it to Europe this summer as well. I was initially hesitant in making this purchase due to the price being $350, but have never looked back. I can honestly say it is one of the best purchases I've ever made. If you are on the verge of making a decision like I was at the time, I definitely (100%) think you should purchase it. You will not regret it. If you spread the cost over the 5-10yr lifespan of the product, then it is extremely easy to justify the cost. It is by far better than a lifestraw and other pumps out there. This is the best water purifier on the market for these reasons: it is the fastest for pumping water, the easiest to use, will filter through dirt, and filters the most contaminants (besides chemicals) vs. other filters on the market. For those reasons, I without a doubt recommend this! 5 stars!
