Understanding Water Filtration: What is a Micron?

When it comes to water filtration, a micron is a term that is frequently used to describe the size of particles that a filter can remove.

A micron (also known as a micrometer) is a unit of measurement that is equal to one millionth of a meter or 0.000039 inches.

To put that into perspective, a human hair is typically around 50-100 microns in diameter.

Micron Rating of Water Filter

In the context of water filtration, the size of the particles that a filter can remove is directly related to its micron rating. A micron rating is a measurement of the smallest particle size that a filter can effectively remove.

For instance, a water filter with a micron rating of 1 can remove particles as small as 1 micron in size, while a filter with a rating of 5 can only remove particles that are 5 microns or larger.

It’s important to note that the effectiveness of a water filter is not solely determined by its micron rating. Other factors, such as the type of filter media used and the flow rate of the water, can also impact how well a filter performs.

However, micron rating is still an important consideration when selecting a water filter.

Common Contaminants in Water & Their Sizes in Micron

To better understand the importance of micron size in water filtration, let’s consider some common contaminants that are often found in drinking water.
