November 15, 2025– OASIS, a leading provider of high-performance filtration screens and tubing for oil, gas, and well applications, is emphasizing the importance of accurate particle size measurement in the design and manufacturing of filtration systems. Understanding the relationship between mesh and microns is critical to ensuring optimal performance in demanding environments.
According to industry guidelines, the conversion between mesh and microns can be approximated using the formula:
Microns = 15,000 ÷ Mesh.
For example, a 200-mesh screen corresponds to 75 microns. Conversely, Mesh = 15,000 ÷ Microns.

Mesh count, also known as the number of openings, refers to the number of holes per square inch.
Key Considerations for Accurate Filtration DesignOASIS highlights several factors essential for precision in filtration:
Definition Clarity: Mesh refers to the number of openings per linear inch, while microns measure actual particle size.
Formula Applicability: The standard conversion formula is an approximation. Variations may occur across different industries and standards.
Measurement Accuracy: Screening methods for mesh and advanced tools like laser analyzers for microns require strict operational controls to ensure reliability.
Industry-Specific Standards: Sectors such as oil and gas often have unique requirements, necessitating tailored approaches to filtration design.
“In oil and gas filtration, even minor deviations in screen specifications can impact efficiency and longevity,” said a senior engineer at OASIS. “That’s why we combine standardized formulas with real-world validation to deliver screens and tubular filters that meet exact client and operational needs.”
OASIS specializes in custom-designed filtration screens and well casings that withstand harsh conditions, ensuring reliability and reducing downtime in oil, gas, and water well operations.
