PURINIZEThe Best and Only Patented Natural Water Purifying Solution - Chemical Free Camping and Survival Water Purification (2 oz)

We took these to Puerto Rico during the aftermath of Hurricane Maria. I used this product in a five gallon container and let it sit for about an hour. I tasted it and it was great! About five days later, I drank some water from the container again and it tasted exactly the same! Good product!

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.

Used this in India for a month and never had any stomach issues. I was extra cautious, however, and filtered the water through my MSR waterworks filter after letting the water sit with the drops in it. This was to filter the sediment that is created by the drops, and also as a backup measure since I was in India after all. This was time consuming, however I felt relieved to not generate so much plastic waste by having to purchase multiple single use water bottles on a daily basis.A fine mesh strainer is necessary for crystal clear water if you only use the drops.

I found that you cannot dispense the solution in drops from the bottle; it just pours out. I placed the solution into a dropper bottle for dispensing. Given the number of reviews that complain about packaging, you would think that the company would catch the hint that they need to take another look at their bottle.

Tossed in a box with a couple of air bags. Leaked all over. Sent back for a return. I wish I could have given a decent review on the product, but when it is packed so poorly that it leaks badly, then that's a bad start and worth a review in itself. I will review the replacement if it arrives undamaged.
