Review on DackWinid Portable Ultrafiltration Personal Emergency by Jason Cavett

See my photos and seller photos, this water filter made in China ensures the transparency of the content and design. The seller even included a spare activated carbon pre-filter in the box. The only concern I have is reflected in my photo where below you can see hollow microfiber tubes wrapped in a U shape. You will see light passing through the outer casing of the filter. I doubt that this would allow contaminated water to shorten the path and avoid going through the filtration process through microtubules. If you look at the photo showing the ends of the tubes, you can see again that there are gaps in the body of the tube that the hollow fibers won't fit in (it's hard to see in this photo, but there's a kind of transparent membrane full coverage of this end). tube body - I'm not sure exactly what the filtering function of this membrane is, but it should do something). I really liked the features offered by this device such as B. The absorbent tube screw-on hard cover, hanging carabiner and a functional neck strap to prevent it from accidentally falling into the water source during use. Finally, the device is accompanied by an informative instruction manual to help users better understand how to use a device of this general type more safely. I would like one of these Chinese manufacturers to put their product through a recognized water quality test. laboratory and enclose a copy of the certified results with the product. Microscopic contaminants in water can cause serious illness and/or death and water quality should not be taken lightly. As of this writing, I would say that at least this manufacturer makes what they do visible for inspection, and that puts them well ahead of other Chinese-origin water filters that I have personally reviewed. While I wouldn't use it outdoors as my primary water filtering tool, I would use it in emergencies - far more than I can say about other devices I've reviewed to date. I hope you find my photos and comments helpful as you review this article.
