Survivor Filter PRO Hydration Extender Pump Water Filter Backwashing System – Virus Heavy Metal Tested 0.01 Micron Water Filter Camping, Hiking Emergency.

I have to say I was very impressed with this water purifier. I thought of buying the electric one but then I thought if I didn’t have a battery, it would be useless so I went with the hand pump one I tried it out on the water in a nearby river, I tested the water first without it being purified and then I purified it and it came out absolutely perfect to drink had no aftertaste to it. This thing is definitely a lifesaver. I bought the kit with the extra filters in my opinion well worth the money it has a back flushing system, so it cleans it back out again , so you’re ready to go again I kind of hate to say this, but the state the world’s in right now it’s a damn good thing to have. I would definitely recommend this to anyone who is a bit of a survivalist like I am and just loves to get out and camp fresh clean water is a must watch. Everyone knows I would definitely recommend getting this for your kit even your go bag. Best of luck thank you for reading it, you have any questions don’t hesitate to contact me

This one apart of my three part emergency preparedness water plan. First I use a 5 gallon bucket to collect nasty water from my local retention pond, then I rough filter that water through a t-shirt (I like the anti-microbial, fast drying kind) into another 5 gallon bucket, then I use this bad boy to physically filter that water to ”0.01microns” and then finally it goes into my Berkey. The Berkey could handle the nasty water straight, but it would shorten filter life, so I prep the water. If I suspect heavy virus content (people are camping/pooping near the water source, flooding, etc) I can treat the water with my solar powered chlorine generator (fits in your pocket) and the Florine’s smell and taste will later be removed by the Berkey. 0.01 microns is the nominal (average) pore size, which means practically nothing, ABSOLUTE poor size (largest pore in the filter) is .025 microns. I’m basing this off of the fact that this filter was tested on a virus .025 microns large with success (it's also what the company told me). This isn’t bad though, the next smallest pore size I know about is the MSR and that’s ranges between $89-$350 with a poor size of .02 and it can only handle something like 396 gallons per filter, not exactly great for any sort of long term solution unless you stockpile lots of filters. Plus, the MSR doesn’t have any activated charcoal which means no toxins are being removed. On that note, it stinks that the charcoal filter on this doesn’t last longer. 26k gallons on the other two filters, but only 528 gallons on the carbon filter. It's not enough to say this isn't the best value water filter on the market (that I've found and I've done lots of research) it just means that it loses its limited heavy metal, bad taste/smell removal capabilities 2.9 months into an off the grid situation for a family of 3, best case, 2 gallons, per person, per day. Still not bad for $65!!!!!!!! Flow rate is good, it takes 10 minutes of non-stop pumping for every gallon of water filtered. Light enough to toss in a cargo pocket, well thought out and engineered, a million times better than life straw and any of their 2 micron filters that leave you wide open to a wide verity of deadly water born illness like Vibrio cholerae, not to mention every viruse out there! With this single $65 device, I can give my family of 3 w/ 2 dogs, 10 plus years of bacteria/ virus/ protozoa free water in an off the grid situation! Problem is, there are a lot more things than viruses and bacteria that can harm you. Heavy metals, a plethora of chemicals and toxins, etc. My very non-mobile, large Berkey, not only takes out all the critters, it also takes out over a hundred other chemicals, poisons, and metals, it even removes some forms of radioactive waste!. With two of these survivor filters (or one of the $100 extended hydration version) and my Berkey I'm ready to provide my family with over 20 years of the cleanest drinking water possible at the drop of a hat, and that's in a off the grid situation, drinking out of a retention pond surrounded by houses, in Florida!

Great purchase. Easy to use. Set up and pumping was quick. I pumped a minimum of 6 quarts of water a day from the silty Green River in Utah for 9 days. It worked flawlessly, the water was crystal clear. I backwashed the pre-filter two or three times during the trip. Take care of it and it will take care of you.

Good product so far. My mom used it for her trip to the mountains. She could filter a lot of water for 5 people. The only thing I didnt like is the price, its too pricy for a filter you will use 3-4 times. The level felt cheap but other than those two things i think its worth it.

love the water pump works great!!
