To decide which water purification system is right for you, you need to compare the possibilities with the requirements - horses for courses . For example, if you are concerned about viruses, a typical 0.1 micron backpack filter is not a good choice. Let's say you've been an international traveler or are concerned about the norovirus. Viruses are the number one cause of waterborne bowel disease and filters do not, and do not claim to, remove them. There are two modern methods of killing all pathogens, including viruses. SteriPens are one of them. The other is Aquamira water treatment drops. Aquamira stops its effects by reacting and forming an oxygenated chemical that does its job. Response and treatment can be easily carried out in remote areas. The whole process takes at least 20 minutes, but most of the time you can walk on. SteriPens work by generating ultraviolet sterilizing light and it only takes a few minutes. The Classic 3 can use any type of AA battery, including rechargeable or emergency alkaline batteries. About 150 liters are obtained from a lithium kit. The SteriPen weighs 141 g including batteries. The 1 ounce Aquamira kit weighs about 75g and holds 115 liters; You can adjust the mix for different volumes, e.g. B. 20 ounces instead of a liter. Another option could be using Aquatab tablets. They create the same oxygen-rich chemical as Aquamir's drops, and they also take about half an hour to work. They cost around ten cents per liter of treated water, while Aquamira costs around one cent. The SteriPen pre-filter is a good addition, although it is relatively heavy. It matches a fancy 22-ounce Nalgene On-The-Fly water bottle, but it's imperfect. A 40 micron filter won't remove haze, let alone pathogens. You can also use a coffee filter or even a bandana. If you don't need to filter out needles and chipmunks, you can insert the SteriPen directly into the drinking tube of a filled bottle. If you use reused 20 oz energy drink bottles to store water, like many travelers do, you can drill a 7/8" hole in the replacement cap and slip the SteriPen in during treatments - perfect, except you must decide whether to use the pint or pint purification options based on the clarity and source of the water. You should be aware that neither system works with water trapped in the threads of containers and both are less effective at cleaning water. bacterial biofilms form on the smallest particles in turbid water. You must be careful not to contaminate purified drinking water with a drop of untreated water in your device, as some pathogens require only a few organisms to cause infection. Be sure to dry this floss and do not brush your teeth with unpurified water. Water treated with Aquamira kills pathogens it comes into contact with while working, so you can use this to your advantage, but water treated with SteriPen is always inert. A concern with SteriPens used to be the lifespan of the UV discharge tube. . SteriPen solved this problem by developing the Premium Lamp Life Pledge. When your registered device reaches 8000 treatments, SteriPen will send you a brand new device. It's one of the reasons I choose the SteriPen when it's appropriate: not because I think I'll ever use it, but because I admire the company behind its products. You need to understand a few things about acquired bowel disease. A waterborne disease doesn't show up right away; Most infections show up after about a week. If the disease comes on faster, the most likely cause is food poisoning. If you get the disease while out walking, you probably caught it beforehand. The most common way bowel disease is transmitted is, um, fecal-oral transmission. To avoid this transmission process, thorough hand washing is necessary when preparing food in rural areas, which is rarely practiced conscientiously. I suspect that almost all clean provincial waters are safe to drink without treatment, except for water downstream of permanent human habitation, but even if you do get infected, you'll be home before the disease hits you.
