Iodine tastes just like it smells, fortunately, this is a pretty weak solution, so the taste is not overpowering; it is only slightly worse than city water. The advantages of iodine crystals, is that, one container can treat somewhere in the neighborhood of 10,000 gallons. As well as the fact that, it prepares the water relatively fast. The disadvantage is, as mentioned above, that it is harmful in the long term.
Water filtration is probably the most common method of purification for personal consumption, mainly because of its versatility and ease of use. Water filtration systems come in many forms and sizes, some of which are even portable. The most common water filtration systems are integrated with household sinks and refrigerators by connecting to the waterline.
A reverse osmosis water purification unit (ROWPU) is a portable, self-contained water treatment plant. Designed for military use, it can provide potable water from nearly any water source. There are many models in use by the United States armed forces and the Canadian Forces. Some models are containerized, some are trailers, and some are vehicles unto themselves.[citation needed]
A properly packed backpack is requisite to your comfort and safety. Incorrect weight distribution leads to muscle aches and unnecessary strain on your spine. Place heavy items – water, food, and cooking gear – in the middle of your pack, close to your body. Use medium weight items – clothing, tarps, and rain gear – to cushion the heavier items, securing them, so the weight does not shift while you are hiking. Pack your sleeping bag in the bottom of your backpack or tie to the bottom. Store items that you are likely to need more frequently in the side and outer pockets – compass and map, sunglasses, toilet tissue and trowel, sunscreen, bug repellent, pocketknife, flashlight, snacks, and a small towel.
The process of distilling seawater into drinking water has been used by the Ancient Greeks since about 200 AD (Wikipedia). Many cultures throughout history have used distillation as an effective method of ensuring potable water. Although the materials used in the distillation process have changed over time, the science has remained the same, proving that distillation is a purification method that has stood the test of time.

The addition of inorganic coagulants such as aluminum sulfate (or alum) or iron (III) salts such as iron(III) chloride cause several simultaneous chemical and physical interactions on and among the particles. Within seconds, negative charges on the particles are neutralized by inorganic coagulants. Also within seconds, metal hydroxide precipitates of the iron and aluminium ions begin to form. These precipitates combine into larger particles under natural processes such as Brownian motion and through induced mixing which is sometimes referred to as flocculation. Amorphous metal hydroxides are known as "floc". Large, amorphous aluminum and iron (III) hydroxides adsorb and enmesh particles in suspension and facilitate the removal of particles by subsequent processes of sedimentation and filtration.[6]:8.2–8.3
Storage – Water from rivers may also be stored in bankside reservoirs for periods between a few days and many months to allow natural biological purification to take place. This is especially important if treatment is by slow sand filters. Storage reservoirs also provide a buffer against short periods of drought or to allow water supply to be maintained during transitory pollution incidents in the source river.
Accidental shootings are an obvious hazard of hunting, but guess what's just as bad: trees. "A tree stand hung 20 feet in the air should be treated like a loaded gun, because it is every bit as dangerous," says Marilyn Bentz, executive director of the National Bow hunter Educational Foundation. Most tree-stand accidents occur while a hunter is climbing, she says.
The water from this unit is pretty much tasteless to me, which is ideal since tap water tastes awful. I grew up with Culligan, which has a certain taste to me, versus this which is just pure. Haven't tested it but plan to. We also added a line to the fridge ice maker so our ice is purified. It was easy to install in our home, and we've used it three months with no issues. The cables are long. today when our sink clogged and we had to drain it, got a mess over all the filters, and they water tubes were all long enough to put the whole unit (still assembled and attached), into the sink to rinse it off. I'm glad it's made in the USA so I know all the parts have stringent manufacturing guidelines. The only thing I would change, is ordering directly from apec instead ... full review
