Water sustains life - but it is not only human life, the necessary water. And 'home to many forms of bacteria and many parasites.
Giardia and Cryptosporidium are two common parasites that cause diseases in humans. Their most common way of transmission to humans occurs through contaminated water. When they are microscopic, there is no simple way to determine if the water is safe. Water from a source not verified should be considered dangerous for drinking water.
Traditional portable waterThe purification was contaminated with the use of chemicals added to the tablets or suspected sources of water contained reached. Cryptosporidium, however, protected by an outer shell that is resistant to chemical disinfection. Filters modern excursions successful claim to protect against this type of parasitic infection, but do they work?
The answer comes to one point - one of the dimensions. Working for a filter with mechanical means, must pore that is large enough, can haveThe molecules of water through small but enough to stop microscopic parasites.
Cryptosporidium and Giardia are protozoa known as the family. Their size can vary from 1 to about 15 micrometers range. To be safe outside of these pathogens, the pores of the filter must be less than 1 micrometer. To ensure removal of bacteria and must be the size of 0.2 microns.
Excursions quality filters using multi-level filters use the technology in ceramic or glass fiber (or both). Ceramic filters area pore size of 0.2 micron glass filter and have a large filter surface repeatedly to 0.3 micron pores.
Each filter of this size not only filter protozoa, even bacteria.
