ItвЂ™s important to note that particulates in the water can impede the effectiveness of UV light and, to a lesser degree, chemicals. However, using a purifying agent like chemical tablets or UV light alone wonвЂ™t remove particles like dirt. Chemical tablets make a great back-up purifier to any microfilter, rendering the water safe to drink by eliminating any potential viruses. If you own a microfilter, you can combat viruses by adding a purifying agent to the water after youвЂ™ve sufficiently filtered it of protozoa, bacteria and any particulates like dirt. You might also choose a purifier in your local backcountry zones if you notice that people arenвЂ™t practicing good hygiene near water sources like popular lakes.Д¬ommon waterborne viruses found in water sources include Norovirus and Hepatitis A. If youвЂ™re traveling to less-developed countries, where water treatment and sanitation infrastructures are poor, a water purifier is the safer option. When should I use a backpacking water purifier? Learn about these testing standards here. EPAвЂ™s Guide Standard and Protocol for Testing Microbiological Purifiers (for removal of bacteria and protozoa). Backcountry-grade microfilters are designed to remove contaminants down to 0.2 microns and should meet NSF protocol p231 and/or the U.S. Some filters in outdoor shops are designed to remove only unpleasant tastes from tap water. It is important to ensure that your microfilter is built to handle backcountry-type water. Therefore, where fewer humans exist, we assume the risk of viruses is also lower. That means viruses that are harmful to humans are transferred primarily by the fecal matter of other humans. Viruses, by contrast, are generally species-specific. These microorganisms can be transferred to you through human or animal fecal matter in the water. In these pristine landscapes, where human traffic is relatively low, the main threats are considered to be protozoa (like Cryptosporidium and Giardia), and bacteria (like E. and Canada, a filter is typically considered sufficient protection. If youвЂ™re traveling in the backcountries of the U.S. While purifiers offer greater defense than microfilters, they may be considered a bit overkill for some types of trips. When should I use a backpacking water filter? Municipal systems readily tackle waterborne pathogens in their treatment methods.) (Please note, the COVID-19 virus has not been detected in drinking water supplies, according to the World Health Organization. While physical purifiers and other purifying agents are great when you need them, a purifier isnвЂ™t always considered necessary on every trip. Now, however, advancements in physical purifiers (as opposed to chemical purifiers) mean you have a convenient way to physically remove viruses along with bacteria and protozoa, all in one easy step. Until recently, UV light, chemical treatments or boiling your water were required to deactivate viruses by scrambling their DNA. Because of this, theyвЂ™re too small for backpacking filters to catch they simply slip through the filter media that filters use. On the microscopic scale, viruses are far smaller than protozoa and bacteria. Traditionally, tackling viruses has been tough for water treatment devices. A water purifier is designed to remove protozoa, bacteria and viruses, offering a higher level of defense. Generally speaking, a water filter is designed to remove waterborne protozoa and bacteria, but not viruses. Put simply, the main difference between a backpacking water filter and a water purifier lies in the level of protection these two treatment devices provide against the harmful microorganisms that may be lurking in backcountry water sources. WhatвЂ™s the difference between a backpacking water filter and water purifier?
