How To Convert Mesh Count to Micron Rating

Wire Mesh | Filtration

In the world of filtration, accuracy is of the utmost importance when attempting to achieve desirable results with wire mesh filters. Having confidence in your results will give you peace of mind and will reward your process in the long run.

Though a small part of your process, this is why being able to convert both the mesh count and the micron rating of your mesh filter accurately is essential. But what exactly do the mesh count and micron rating of woven wire mesh entail, and how do you properly convert the two?

W.S. Tyler has been helping customers weave wire mesh filters into their process for over 150 years and is here to educate you on the specifications you need to understand to succeed.

With that, to better prepare you for what to expect when developing your next wire mesh solutions, this article will encompass:

  • What mesh count is
  • What micron rating is
  • How to convert mesh count to micron rating and vice versa
  • Why it's important to know both the mesh count and micron rating


What Is Mesh Count?

When looking at a mesh filter, the mesh count refers to the number of pore openings in a linear inch. As this is typically how a given piece of mesh is classified, having a filter that is 100 mesh means that the filter should have 100 openings if you measure an inch in any direction.


Naturally, this means the smaller the mesh count, the finer the mesh filter is considered.


What Is Micron Rating?

Micron rating is best defined as the distance between any two wires that make up a mesh filter. This metric is used to determine the amount of open space that is not taken up by the diameter of the wires.


Converting Mesh Count and Micron Rating Accurately and Efficiently

As you venture into the world of woven wire mesh filters, you will find that some wire mesh suppliers use micron rating and mesh count interchangeably. When designing a mesh filter, it is crucial that you can convert these two metrics, as this will allow you to clearly communicate your needs with the manufacturer.

To help, we have created the table below as a guide to convert these metrics quickly:

Why Mesh Count and Micron Rating Are Important

So, we've discussed what mesh count and micron rating are and established how to convert them. But why exactly is knowing these metrics so important?

Well, it all comes down to achieving optimal results.

By knowing the mesh count your process requires, you can feel more confident in the control you have over what does and doesn't pass through your mesh filter. To that end, knowing the micron rating will allow you to control flow rate and throughput, helping you create a more efficient operation.


For a more in-depth breakdown of how mesh count and micron rating compare in regard to wire mesh performance, refer to the article below:



Ensure Optimal Wire Mesh Durability With the Right Alloy

Mesh count and micron rating are integral mesh specifications that control the performance of a mesh filter. Knowing how to identify and convert these specifications will allow you to implement a wire mesh solution that delivers the results you need to achieve peace of mind.

Once you have established the mesh count/micron rating needed to build your wire mesh filter, the next step would be to determine what alloy should be used to weave the mesh. This will ensure your filter will be able to withstand the various elements, such as heat, pressure, and corrosive material(s), your process will subject it to.

W.S. Tyler has come to understand the frustrations of constructing and fine-tuning a filter/screening solution that performs efficiently. This is what drives us to use our decades of experience to help pinpoint a happy medium that best suits you.
