Water Filter Micron Rating

A micron is a unit of measurement describing the pore size of a micron water filter.

Water filter micron rating.

This is an incredibly small measurement which is hard to visualize but it is vital to know the micron rating at the microscopic level filters operate. Although a water filter with a smaller number micron level will catch more contaminants it will also clog faster and easier. For example first filter the water through a 20 micron sediment prefilter then a 5 micron and finally through a 1 micron or a sub. Micron size for water filters.

Know what needs to come out. Sediment filters remove different contaminants depending on their micron rating. Knowing what is in your water is the first step in determining what micron rating the water filter has to be. It is important to note how critical it is to remove all contaminants ask yourself would a nominal micron rated filter do or is an absolute one required.

Micron levels are used to determine the size of particles that a particular filter can remove. Since treated water is free of these types of organisms a 1 micron filter is not necessary. A micron is the same as a millionth of a meter or 1 1000 of a milimeter. Another thing to note is that when you install a water filter with a lower micron rating you also lower your flowrate.

In a well water situation it is common to see two or three sediment prefilters in the water flow starting with the higher micron rating to remove the larger particulate followed by lower micron rating filters.
