The Best Patented Natural Water Purifier - Chemical-Free Solution for Camping, Hiking, and Emergency Survival

Update: I've added photos showing the use of Purinize on my tap water using a cloth as filter (showed my Sawyer bag as well since that's what I usually use). Water tasted much better (usually has a metallic taste) even though not much sediment showed on the cloth._______I truly enjoy this product. Working as a ParkRanger near Glacier and Yellowstone National Parks gives me plenty of opportunities to hike and camp in the back country. One of the most convenient aspects of this is the dropper-top. It makes for ease of use and to keep from cross contaminating. When flying to places like Yosemite I prefer to only take a carry-on and this package is travel size. It doesn't have an expiration date and it starts working in an hour. Once the solution is processed it creates a sediment that works in tandem with my Sawyer filter. You can use a coffee filter otherwise. The result: great tasting, pure water.
