The Best Water Purifiers for Camping
Water is one of the essential ingredients in both life and camping. Adults require at least two liters of water to replace lost fluid every day. Weighing more than eight pounds a gallon, it’s no fun trekking in water for one person let along a large group. Pump filters and drip filters are a great alternative to lugging water storage containers to remote campsites. Most pumps weight less than 12 pounds and have a capacity to filter enough water for groups of six or more campers.
Gravity and Drip Filters
Base camps and cabins offer all the amenities a camper needs. Having a readily available source of purified water is important for solo campers and group expeditions. On camping trips, it’s always fun to plan day activities and return to the base camp for some fun, food, and well deserved relaxation. When it’s time to cook dinner or fill-up the portable hydration bladders, it’s inconvenient to use a hand-powered filtration pumps. Fortunately, there are large-capacity, gravity-fed drip filters that take all the work out of purifying water.
Gravity-fed filters start at approximately $70. Katadyn‘s Base Camp model is an affordable, portable, large-capacity water filter that is great camping in the backcountry and sites without vehicle access. The Base Camp model is essentially a waterproof bag designed to emptied and refilled between campsites. The 2.6 gallon water bag simply straps around a tree and uses gravity to filter water that is manually released through the flow valve. Using a HikerPRO filter with activated charcoal and AntiClog technology, the Katadyn Base Camp removes all types of disease-causing pathogens larger than .3 microns. The gravity-fed filter has a 200 gallon capacity and processes one gallon of water in less than 10 minutes. Replacement glass-fiber filters cost approximately $40.
For camping and hunting cabins, RVs, families, and groups of six people or less, Katadyn’s Ceradyn and Gravidyn drip filters are an ideal choice. The Ceradyn and Gravidyn are essentially the same model of countertop water dispenser, however, the filter technology varies slightly. Prices start at $220 for the Gravidyn, which uses a ceramic and activated carbon filter.
The Gravidyn filter has a maximum life of six months. The Ceradyn model, which is priced at $250, includes three cleanable ceramic depth filters. The Ceradyn system has a capacity of 40,000 depending on the water quality. Replacement filters for the Ceradyn cost approximately $69 and each unit requires three filters. The system housing measures approximately 18″ tall and includes two 2.5 gallon reservoirs. The filters and unfiltered water reservoir sit above the cistern and pure water dispenser. Drip filters produce one gallon of pure water every hour.
Although drip systems are slow, the Ceradyn and Gravadyn have no moving parts, which makes them one of the most reliable options available. When unfilled, Katadyn’s drip filtration systems weight less than ten pounds, making them highly portable despite their large capacity.
