Water Purification Tablets, Portable and Effective Water Purification Solution for Camping, Hiking, Emergencies, Natural Disasters and International Travel, Two 50ct Bottles, Blue

Goid to have in case of an emergency

There are two major approaches to purifying contaminated water: you can try to trap sediment and microorganisms via a filter, or you can use various methods to sterilize the water by killing anything living in it. For absolute safety, some recommend doing both, so I'm not going to sit and compare tablets to a pump filter, as they are different mechanisms of purification that aren't necessarily competitors. In fact, regardless of how you kill the bugs in your water, I recommend at the very least running the water through a cloth/bandana first as a first step in removing dirt and larger microorganisms. That gives these tablets three major competitors... The first, and cheapest, competitor is good old-fashioned boiling of water. In fact, boiling kills most things that some chemicals might not even get to. The downside, of course, is the need to start a fire, wait, and boil water. Good if you're camping overnight and prepping for the next day, but not so great if you need to fill up in the middle of a several-hour trek. If you're the kind of person who carries a mini-burner and a stove-top anyway, you probably don't need these tablets. The second, and most expensive, competitors are the UV light devices that sterilize using light. It sounds like nonsense, but it does in fact work. The problem is the cost and reliability. Sure, it can be argued that if you break down the cost per liter of water of a sterilizing pen is actually lower than using tablets, but that's only assuming that you actually get the maximum number of cycles that the manufacturer claims it is good for, and it ignores the cost of the batteries and the reliability of the products. From my experience (luckily, not with gear that I had to pay for), the SteriPEN is finicky from time to time. Unless you're doing light day-hikes, I wouldn't rely on batteries and electronics to hold up. Especially over years of hard use and being banged around in a backpack. It's nice having neat technology to show off, but nobody will be impressed when your magic light is broken and you're crapping your pants (literally). The third source of competition is other tablets/drops. There are several types, and while some tout better flavor, more effectiveness, etc, it really comes down to whether it'll kill the bugs in whatever area you're hiking. In other words: most of them are the same unless you're headed to an area with a very specific rare microorganism that certain tablets won't kill. These have held up for me through years of trekking on four different continents. That's quite good enough for me. The taste, sure, is a bit off, but it's nothing unbearable. Between tablets, I don't have much of a preference, but I do prefer tablets over liquid drops, as they're easier to carry and use.

I bought these tablets on a recommendation for my emergency kit, but I got to try them out during a recent hiking trip. We used them to purify water from a stream, and it was a total success. The water was clear, had no strange taste, and I didn’t have any issues after drinking it. I’m really glad I tested them—they’re now a must-have in both my backpack and my emergency supplies.

I'm gonna give this product a good review because of its small size and price, but I have not tried them in water I have to drink for survival. My only hope is that they work when I need the but I don't plan on being that adventurous to find out right now...LOL

I bought these because I read that Clorox deteriorates and thus can't be trusted to disinfect drinking water in an emergency. These can retain their potency in long-term storage.

Las guarde para alguna ocasión dificil parecen buenas

Likely will never need these, but like having them in the closet. Rather inexpensive insurance. Have not tried them.

ty works great

I love the fact that this purifier is in such a small container that you can carry it wherever you go. brilliant

Very fast shipping and packaging is just like the picture but haven't opened or tried them yet so will have to wait and see. I did read adding vitamin c in the water can help neutralize the iodine taste but only after 34 minutes when the iodine is finished working/purifying. ******************************************************************** Some other comments about it on the internet.... The chemical name for vitamin C is ascorbic acid. When Iodine and ascorbic acid are combined in solution, a chemical reaction takes place. In this chemical reaction, the ascorbic acid molecule loses electrons, which are transferred to the iodine molecule. Chemists call this type of reaction an oxidation/reduction reaction (or redox reaction for short). The ascorbic acid is oxidized to dehydroascorbic acid, and the iodine is reduced to Iodide ions. Oxidation-reduction reactions always occur in pairs like this. The molecule that loses electrons is oxidized, and the molecule that accepts the electrons is reduced. ************************************************************************ Guess what else - it is an instantaneous chemical reaction. The ascorbic acid complexes the iodine on contact, removing both taste and color. Try it in a clear container. Watch the color disappear entirely before your eyes in a heartbeat when you invert the container to mix it. That color change tells you it's done. There is an important caveat: it only takes a VERY tiny amount (fits easily on the tip of a knife blade) of ground-up vitamin C tablet to do this in an entire gallon of water. Be advised that you will always add more than you really needed. No big deal UNLESS you forget to thoroughly rinse the water container before you add iodine the next time.

未だ、使用してませんが欲しい物が手に入り嬉しく思います。

This Potable Aqua is a great product to have in your emergency or camping kitbag. It provides drinkable water when clean sources are not available, ensuring you always have a safe supply. A must in these dangerous times.

Aunque vienen dos frascos, cada frasco cumple con una función diferente: uno desinfecta el agua y el otro le quita el color y sabor a yodo. Para cada litro de agua se deben usar 2 pastillas de cada frasco (cada frasco trae 50 pastillas), así que solo se pueden desinfectar 25 litros en total. Me habría gustado que esta información estuviera más clara antes de comprar el producto y por ello lo pongo en comentarios, pues nosotros nos fuimos con la finta de que ambos frascos eran iguales y que tendríamos 50 usos. Otra cosa que no se especifica en Amazon pero es importante es que estas pastillas no están pensadas para un uso continuo, y es algo en lo que sí se hace hincapié en las instrucciones del producto (las cuales vienen en inglés, pero pueden consultarse en español en el sitio web de la marca). Ellos dicen que no se debe usar el producto de manera continua, lo cual, de nuevo, nos perjudica a nosotros que sí pensábamos en un uso continuo. Las pastillas son muy pequeñas (como los chochos de farmacias homeopáticas) y los frascos no miden más de 6 centímetros de alto, para que tampoco esperen algo muy grande. Esto resulta práctico para traerlo en la mochila sin que ocupe espacio. A diferencia de las soluciones líquidas, las pastillas no tienen que estar en refrigeración pero sí se indica que el frasco debe estar perfectamente cerrado y que, una vez abierto, se consuma antes de un año o se deseche por cuestiones de seguridad. Por último, el tiempo de purificación del agua entre que se agregan las primeras pastillas y las segundas es de 40 minutos, algo que me parece importante a tener en cuenta.
