"In the event of a power outage, our well would cease to function. Having a backup filtration source, such as the Lifestraw Peak Series Gravity bladder, provides peace of mind in the event that we need to use local river water for drinking."
"This is an amazing prauduct! You can get a lot of water really fast with this purifier! I love it!"
"We are thrilled with the products we purchased - the quality, ease in functionality, and peace of mind are next level!"
"Really good quality and the price is fair"
"Bought this for backpacking last year and it works great ive been able to hang it anywhere ive needed with a bit of creativity and the big bag is great for carrying all the water we need to our backcountry camp 200’+ from the water. Its a bit heavier (duh) but well made and worth it for peace of mind when the water source is looking sketchy."
"As an overlander in a capable vehicle, I frequently find myself for many days in areas where potable water is unavailable. This filter virtually eliminates any water anxieties as long as some body of water is nearby, an eventuality for which one can normally plan. It is constructed extremely well, I can carry it to and from the water source over my shoulder with the strap, thus permitting me to carry a second bladder of raw water to filter back at camp after the first one finishes. If you’re a backpacker, this might not be your ideal option because of its size unless you’re with a group, but for my purposes, I frankly wouldn’t consider any substitute. This filter it’s fast, effective, and tough as nails. Thanks for an excellent product."
"We bought it as an emergency prep"
"I ordered this product after extensive research online. This gravity purifier is the best one on the market in its class. The website was very informative and easy to use. Delivery was quick and the purifier was packaged well. I purchased it for emergency use and not for routine camping use, so I have not had a chance to use it yet. But, I did examine it when I received it and the materials and build quality are great!"
"This thing works great. Not only does it filter quickly but it's built stronger than the other gravity bag filters while being versatile in use. You can fill it easily then transport a full bag without a sweat, plus it hangs from strong connections and the filter back flushes to extend it's life AND it can kill viruses. We filtered over 30 gallons of cistern and hydrant water ( nasty stuff ) and it never slowed down. Hang it so the tip of the hose extends all the way to a few feet off the ground and the pull of the water speeds the flow rate. It actually makes the water taste great making for better coffee. It rolls up neatly and stows in a ruck without fear of being torn or cut. While not a light weight it can serve 5 or so people quickly making up for hefty construction. It's going to get a work out this summer but I think it will come through without a hitch."
"This water filtration system works by gravity. I did not have to do any pumping or need to use batteries. I love that it is so low effort. Not only does it remove viruses, bacteria, and parasites. It makes the water taste better. This is great for camping and whatever outdoor adventures that you want to pursue. This water purification system will be vital for emergency preparedness and survival situations. I sleep better at night knowing that I have it for whatever comes my way."
