How to Choose the Best Backpacking Water Filter
Since all the above filters and purifiers we tested and reviewed top the list in the market today, you may still not have an idea of what you need. In all fairness, this is because you probably do not know the specifications you may need. The choice of a water purifier or filter depends on several factors. Some of them include;
Do you need a water purifier or filter?
Speed and Efficiency
Type of Filter
Do you know the difference between filtration and purification? Well, this is the first step when you need to make a decision of which equipment to invest in. A water filter physically restrains protozoan cysts (giardia and cryptosporidium), silts and debris from getting into the clean water chamber. Although that statement defines succinctly what purifiers do, modern filters incoporate a technology that enables them to also filter out bacteria, viruses and fungi which are traditionally reserved for water purifiers. In addition to what filters do, purifiers also remove all minerals and chemical contaminants from water. Most purifiers in the market use reverse osmosis to perform the purification process. We advise that you read the description of the equipment you want to purchase thoroughly to comprehend what exactly it is capable of getting rid of from dirty water. Read this article to understand more about water filtration and purification.
So what should your choice be? Well, a water filter is good enough for use in America, Canada and a few other developed countries where the main water impurities are protozoans, debris and bacteria while it is highly advisable to consider a purifier for international backpacking where water is highly infested with viruses.
Who wants heavy outdoor gear when out camping, hiking, fishing or backpacking? The choice of a good backpacking water filter depends on how lightweight and packable you want your outdoor gear to be. A good backpacking water filter should be easy to carry along during your expedition.
What amount of water will you possibly need during your trip? Are you a group or just an individual? How patiently can you wait for the water to purify and/or filter? These are some of the questions that should guide you into choosing a good backpacking water filter. There are expeditions where time is of great essence and you cannot afford to wait for a slower equipment.
There are a wide range of filter types in the market and all these require knowledge to make the right choice. Gravity type filters are currently a common type. Their main advantage is that the gravity force will do all the work for you which makes it possible to process larger quantities of water with less effort. The treatment process is however much slower than the pumping process. Another challenge with them is that field cleaning is needed for optimum use.
The second category is pump type filters. These filters can process the precise amount of water that you need. They are also ideal for pulling water from both shallow and deep wells unlike with gravity filters that are a hassle to fill up from shallow wells. Their disadvantages include the tiring task of working the pump and the fact that they are usually more bulky than most filter types.
Ultraviolet light purifiers are another new entrants into the industry. They are fast and will deliver clean drinkable water in seconds. These filter types also do not require any replaceable cartridge or elements. However, they require power batteries and are not very effective with cloudy or silt water.
The final category are squeeze and straw filters. They are small, highly portable and fast. However, straw type filters will only help you access treated water when you are at the source. For squeeze or bottle filters, the quantity of water you can carry along is limited.
While it's not an easy task searching for and settling for a backpacking water filter, the process shouldn't be entirely impossible. We have done our best to offer you a reliable list of the best water purifiers and filters that will see your camping and outdoor excursions being nothing but memorable. And whether it is a simple filter or a water purifier suitable for a group of backpackers, we've got your interests covered.
