Storing clean, filtered water is essential when in the beginning stages of building up your emergency storage supplies. There are a variety of ways to make sure the water that you plan on drinking is safe. Boiling, distillation, reverse osmosis, deionization, chemical purification and filtration are the most common techniques. Today, we are going to specifically talk about how a water filter works and what options you have in regards to portable water filters.
How Does A Water Filter Work?
Most water filters have tiny openings or a mesh that filters out the bigger particles, like dirt and sediment. Next, the water will pass through a polyester filter (mesh is a little smaller). This filters out clusters of bacteria. The most important part of the water filtering process is when it passes through a chamber of beads that contain iodine. This will kill 99.3 percent of bacteria and viruses. The final step before it reaches you is having the water pass through a chamber of granulated active carbon (GAC). This improves the taste and smell of the water. It will also filter out any remaining parasites.
Many people already use water filters in their homes. Usually, they are attached to their faucets or used with a water pitcher. Typically, these water filters use some sort of carbon filter, micro porous filtration or a combination of the two to purify the water. Portable water filters like the Berkey Portable Water Filter use the same methods to clean water. Hikers, military personnel, survivalists and other people in harsh climates use portable water filters on the go. The filters are designed to remove and reduce toxic chemicals, heavy metals, volatile organic compounds, trihalomethanes, detergents, pesticides, herbicides, chlorides, pharmaceuticals, petroleum-based products, unpleasant tastes and odor, silt, sediment and chlorine. 1
Advantages of Portable Water Filters:
- Allows for quick access to safe, purified drinking water whenever you find a water source
- Removes debris from the water it is filtered
- Portable and simple to use and maintain
There are also other types of portable water filter like the MSR Miniworks and the Katadyn Combi that contain ceramic filters. Keep in mind, that ceramic water filters, while designed for outdoor backpacking, hiking and military use, still need to be handled carefully. If dropped or damaged, the filter can get very small hairline cracks in it that will allow larger molecules to get through the filter and make it not safe to use.
What a Portable Ceramic Water Filter Can't Do:
- Remove viruses from water sources such as Hepatitis A and Rota virus
- Remove chemicals all chemicals from the water
- Remove salt from the water
Take the first step towards preparing to be more self-reliant and add water filters to your storage! Whether it be for your next hiking trip or for a disaster, you can never be too careful when it comes to drinking safe, filtered water.
