I wish the the hose connections were designed to have a barb the help keep the hose attached. Only have one complaint, I cut the hose for my camelbak and use it in-line. This little filter works great super light weight. It is compact, light-weight, versatile (in-line and screw-on/squeeze) and effective. Love my Versa Flow water filter: the flow rate is as good or better than any others I have tried. I guess it would work with a collapsible bottle with a compatible screw opening. I ended up unscrewing the Versa Flo to allow air in, which made the thread pointless. However, drinking from the filter when screwed into a bottle means you are fighting against an increasing vacuum as you draw water out, collapsing the bottle, as there is no pressure release valve. I also attached a flexible tube to reach into bottom of the bottle. Previously I experimented with screwing it into a bottle, once I found one that fitted (Coke and Lucozade work). I still prefer drinking directly from streams, but this was useful where the source was questionable. It's not like drinking through a straw! I also found that water I drank through it had a strange, synthetic flavour. It also requires quite a bit of sucking power. I can say that although it weighs 45g dry, it weighs about double that when in use (because it's full of water). I can't comment on how good it is at removing bacteria, etc. I would fill a 500ml mug from a stream, put the filter in and suck the water through it. I have done three, two-week walks since and only used it during my last walk. Lightweight and low cost, the Versa Flow should be in everyone's backpack, survival gear or travel bag. Check out the Clear Flow if you are concerned about heavy metals or chemicals in your water. Generally viruses are not found in North America or in municipal water supplies around the world. The Versa Flow water filter does not remove chemicals or viruses from water. This means no additional filters, cartridges, pumps, iodine drops, or batteries to ever buy again. If you consistently backflush the filter you can use it almost indefinitely. The Versa Flow allows you to be able to backflush the filter, clearing out all of the particulate and increasing the lifespan of the filter. If the core of the tubes become clogged from sediment on the competitors filter you can no use the filter. This dramatically increases the surface area and flow rate of the filter while protecting the filter integrity itself. We filter water through the outside of the tubes by bending the hollow fiber. Some manufacturers filter the water through the core of the hollow fiber tubes, but this restricts water flow because only so much water can fit through the core opening. All of these organisms are too large to fit through the 0.1 micron holes. coli, protozoan cysts and Cryptosporidium. Meaning the hollow fiber tubes have thousands of tiny holes (0.1 microns) that block 99.999999% of harmful bacteria, Giardia, E. Hollow fiber works through size exclusion. The Versa Flow has many tiny tubes called hollow fiber. Every filter is built to exacting standards and exceeds EPA standards for filtration. This water filter is perfect for backpacking, hiking, camping, travel, and emergency preparedness.Īlthough it is lightweight, it is heavy in features. Weighing in at only 2 ounces you don’t have to worry about adding extra weight to your pack or try to find a dedicated spot for it. The Versa Flow water filter is one of the lightest and most convenient personal water filters on the market. It easily adapts to your lifestyle and can be screwed onto a plastic water bottle, used inline with your hydration pack, used as a gravity system or bucket filter, or can be used as a straw so you can drink directly from the water source. The Versa Flow was designed to be as versatile as you.
