Generally speaking, a water filter is designed to remove waterborne protozoa and bacteria, but not viruses. A water purifier is designed to combat all three classes of microbes, including viruses\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli style=\"font-weight: 400;\" aria-level=\"2\"\u003e\u003cspan style=\"font-weight: 400;\"\u003eBecause North American backcountries are regarded as low-risk for viruses, filters typically offer a sufficient water treatment method. In places heavily trafficked by humans or where sanitation systems are poor, the risk for viruses increases. In these areas, such as in developing countries, a purifier is recommended\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli style=\"font-weight: 400;\" aria-level=\"2\"\u003e\u003cspan style=\"font-weight: 400;\"\u003eAdditionally, filters physically remove matter and microbes from the water. In contrast, a \"purifier\" can employ a variety of methods to do so, from physically removing the contaminants to disinfecting the water of them, through UV or chemical treatments\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli style=\"font-weight: 400;\" aria-level=\"2\"\u003e\u003cspan style=\"font-weight: 400;\"\u003eWhy the two treatment device options? The reason is, viruses are just too small for filters to catch. Far smaller than protozoa or bacteria, viruses slip through the technologies used in backpacking filters. Traditionally, UV light, chemical treatments, or boiling were required to deactivate viruses by scrambling their DNA or killing them. Today, new advancements in physical purifiers provide a convenient option to physically remove viruses quickly and easily\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli style=\"font-weight: 400;\" aria-level=\"2\"\u003e\u003cspan style=\"font-weight: 400;\"\u003eThe flow rates of physical purifiers are generally slower than that of filters, because the internal media that removes contaminants has to be small enough to capture tiny viruses.
