Safe, clean drinking water is a priority when heading off on any hiking or camping trip. Water is a common source of illness as it is an environment favored by by bacteria and parasites. To stay well, the hiker has the choice of carrying their water in or making water found along the way safe. As each liter of water weights one kilogram, carrying a suitable amount is often not an option. This is where water microfiltration is very useful.If you wish to learn more about this, visit best backpacking water filter .
A water microfilter works like any other filter. It prevents the passage of certain materials while allowing the passing of others. The difference with microfilters is the size of the pores. Bacteria, protozoa and parasites are small. Very small. To prevent all of these pathogens from getting through the holes in the device, the pores, need to be only slightly large than water molecules.
The type of microfilters used for hiking have pores between 0.3 and 0.2 microns. A micron is one millionth of a meter so these are small holes indeed. Most devices have multiple stages the water passes through before the process is complete.
Modern filters can be ceramic or made of glass fiber. Ceramic ones often have smaller pores and can filter very fine particles. Glass fiber, although having larger pores, has a very large surface area that has a high capacity to absorb sediment and pathogens.
The other common component is activated carbon. This removes tastes and odors as well as chlorine and pesticides. It ensures the water you drink tastes as it should.
