Details
- How is a Filter Different From a Purifier?
- The main difference lies in the level of protection they provide. 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
- Because 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
- Additionally, 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
- Why 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
- The 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. This slows the rate at which water passes through the media, decreasing overall flow rate
- Standards and Certifications
- NSF P248 Testing Standard
- The most rigorous scientific certification for proving a treatment device safely removes claimed contaminants from challenging wilderness water sources. Guardian devices are the market’s only purifiers to pass the military standard P248 testing for virus removal
