When camping or hiking, it is imperative to keep your body hydrated to promote its functionalism and efficiency. Dehydration is the term used to describe the lack of enough water in the body. It often results in muscle crumbles and lack of enough energy as well as concentration. Unfortunately, most of the water sources found outdoors is contaminated with disease-causing pathogens that could cause many diseases such as typhoid. It is therefore recommended to invest in the best water filter for backpacking in the current market and carry it during this kind of outdoor expeditions.
What is the Best Water Filter?
Water filters are fitted with special filters that help to get rid of the disease-causing pathogens in the water. Just like any other backpacking item, there are some factors that you need to put into consideration when scouting for one to get value for money. To help you find the best survival water filter in the market with ease, we will compare two different filters that are used to purify water in the wild as well as at home. It is our sincere hope that this information will help you make an informed decision in the end.
Water Filters vs. Water Purifiers
Most people use these two terms interchangeably not knowing that they are different. Understand the difference will greatly help you to make the right decision and cushion you from the various waterborne diseases. Let us get down to business and look at how each of these functions and the main differences that you should know.
Water filters are engineered to clean water by physically staining the protozoan cysts and bacteria such as E. coli, Shigella, Campylobacter, and Salmonella. The most dangerous protozoan cysts found in plenty in water include Giardia lamblia and Cryptosporidium. These bacteria and protozoans are a major concern for people who love spending time outdoors in Canada, and U.S. Drink water that is contaminated with either of the two is highly discouraged due to the many health complications that could arise.
Water purifiers are also designed to combat viruses that love hiding and breed in water and other moist places in the wild. One of the benefits of a water purifier is that it can filter out even the tiniest viruses that other equipment is unable to deal with well. If you intend to go hiking or camping in remote areas, be vigilant of viruses such as norovirus, rotavirus, and hepatitis A.
How Water Filters and Water Purifiers Work?
Knowing how a water filter or a water purifier works will help you to use it correctly when you are alone in the world. More importantly, if it develops any complications, you will be in a position to repair it like a professional. The first thing to note is that filters and purifiers have an internal cartridge or element that has microscopic pores for trapping debris, bacteria, protozoa, and viruses as the water runs through the element to the collection area.
Most of the water purifiers in the market rely on chemicals such as iodine to kill the viruses that the elements are unable to catch. Over time, the element gets clogged up with stained matter and other forms of debris. Based on this fact, it is recommended to replace the element with a new one regularly.
There are also manufacturing companies that use activated carbon in their products elements. One of the pros of using activated carbon is that it has the superior capability or getting rid of not only viruses and bacteria, but also unpleasant tastes from leaf tannins. More importantly, it can reduce the level of contaminants such as industrial chemicals and pesticides from the water.
Do You Need to Invest in a Pre-Filter?
Most of the water sources found in the wild contain high amounts of glacial sediments, leaf debris, and mud. These natural components may not cause any harm to your body but could affect the effectiveness of the filter to purify the water. Having a pre-filter at hand will help get rid of them and prepare the water for the final treatment using the water filter.
Ideally, the pre-filter is designed to get rid of large particles from the water thereby making the water treatment process more accurate and efficient in removing the disease-causing pathogens. Some filters come with one, if not; you might have to purchase one separately especially if you are using a UV filter. It is also important to point out that the pre-filter will promote durability of the element inside the filter since it will have to deal with less debris.
Types of Backpacking Water Filters
