While it is true that water is one of the elements that can sustain life here on Earth, it’s not only us human beings who need water to survive. Parasites and bacteria also thrive in water. Some of the most illness-causing microscopic parasites like Cryptosporidium and Giardia love to stay in the dirty water.

Since they are very small and almost cannot be seen by the naked eye, you would have a hard time telling if they are present in the water that you are about to drink. For this reason, it is not safe to drink from just any source of water without determining or confirmation that the water is indeed clean.

Ever since hiking water filters were invented, hikers are wondering if this product can eliminate the microscopic parasites which were mentioned earlier. The answer is that it depends upon the size of the holes of the filter. Giardia and Cryptosporidium are usually 1-15 microns small. In order for them to be filtered out, the size of the filter must be at least 0.2 microns. The smaller the holes of the filter are the better. Water filters must use glass fibers or ceramic technology to be considered as good quality.

Oftentimes, ceramic hiking water filters have a 0.2-micron pore size. On the other hand, filters that use glass fibers have 0.3-micron pores. If you purchase a filter that has dimensions like these, you can be sure that it will be able to remove both protozoa and bacteria in the water.

Don’t forget to assess the dimensions and statistics of the product first before purchasing one. Always remember that the pore size of your water filter must always be 0.2 microns to make sure that the water that it gives you is both parasite and bacteria-free. Having a good filter could be one of the best pieces of camping gear you could own.
