When people are camping, safe drinking water isn't always available. Water that looks clean might still be filled with bacteria, parasites or other contaminants that can induce vomiting or diarrhea, which can quickly lead to dehydration. Camping water purifiers are portable devices that people can use to easily turn any water into water that is safe for drinking. They use complex filtration and purifying systems to remove microorganisms and other impurities, and they might be able to hold a certain amount of water after purifying it. Many people believe that camping water purifiers improve the taste of water in addition to removing potentially harmful contaminants.
The outward appearance of a camping water purifier is relatively simple. It typically has a handheld pump and an intake hose that is placed into an available source of water, such as a lake, pond, stream or river. Most camping water purifiers can be attached to a water bottle or have one built in. They also can be held over containers such as cups or pots, into which the water will flow after being purified.
The inside of the camping water purifier is where the complex purifying process occurs. When the water is drawn into the purifier, it is run through a filtration system to remove large sediment and organisms. The filtration system usually is composed of activated charcoal. The filtered water then passes through an iodine system where fine sediment and microorganisms are removed. The purified water is then emptied into the water bottle or other container where it is stored until it is needed.
Types and Sizes
Camping water purifiers are sold in different sizes and styles that can be used in various types of outdoor recreational situations. Larger water filters might work efficiently for camping in motor homes, campers or other vehicles, but size and weight usually are major considerations for people who want to take along water purifiers when they go hiking or backpacking. Some camping water purifiers are lightweight and small enough to fit into day packs for hikers.
A camping water purifier is a useful tool for many activities. It can break easily, however, because of its complex parts and purifying system. It is recommended for users to carry water purification tablets with them in case the water purifier breaks or malfunctions. Water purification tablets typically contain iodine, halazone or chlorine and can purify about 1 quart (0.95 liters) of water. The water might have a slightly bad taste, but the tablets will prevent people from getting sick because they drank contaminated water.
