0.22 micron
A micron size of 0.1 to 0.5 is considered the most effective for a water filter as it can remove smaller particles and contaminants from the water.
1 micron = 0,000039 inches = 0,001 mm 0,22 micron filter means that it is a filter which will filter particles above (0,22 x 0,001 mm) 0,22 µm (micrometer) in size. Filter paper (or paper filter) is the type of filter used.
The pore size of a filter allows it to prevent the movement of certain particles depending on the size of those particles. The smaller the size of the pores, the smaller the set of particles which can pass the filter. A filter with 0.2 pore size can prevent most forms of bacteria and some very large viruses from passing through the filter since bacteria tend to range from about 0.1 micrometers to 600 micrometers. Many viruses are less than 0.1 micrometers, however, so a 0.2 micron filter is not nearly as effective for viruses.
