Mesh filter is also a kind of woven wire mesh. Different weaving methods—such as plain weave, twill weave, and mat type—create meshes with suitable filtering accuracy.
These meshes effectively separate gas, liquid, and solid impurities. With excellent durability and reusability, they are widely used in water treatment, food processing, chemical production, pharmaceutical manufacturing, and more.
FUDAS has rich experience in mesh filter products.If you are considering using or purchasing related products, please continue reading this blog. I will give you a comprehensive introduction to the selection and application of filter mesh from multiple aspects such as product specifications, applicable scenarios, and post-maintenance.
Affecting Mesh Filter Specifications
Before choosing a filter, we first need to understand what factors affect its performance, scope of application, and price. These core parameters will directly determine whether the filtering effect is up to standard and whether it is suitable for your project.
Mesh Filter Size
“Mesh” is an important indicator of the filter, indicating the number of mesh holes in one inch length. The higher the mesh, the smaller the mesh and the higher the filtering accuracy.
For example, general food-grade filtration typically uses mesh sizes between 80 and 200. Manufacturers use these to filter out particulate impurities and microbial residues.
In other industries—such as chemicals, electronics, and metallurgy—users choose higher or lower mesh ranges based on specific filtration requirements.

Wire Diameter
Wire diameter refers to the thickness of the wires that make up the woven mesh. It affects several key factors, such as mesh strength and rigidity, permeability and flow rate, and pressure resistance.
1.Thicker wires provide greater strength and durability; however, they may reduce the overall flow rate.
2.Thinner wires allow for higher permeability and are better suited for high-precision filtration.
Weaving Types
Different weave types will affect the mesh shape and filtration effect. Common types include:
1.Plain weave: most commonly used, uniform pore size
2.Twill: suitable for high-intensity and high-load filtration
3.More weave types of wire mesh filters
4.Mat type: used for ultra-high-precision filtration, extremely small pore size
Material Selection
Different materials are suitable for different environments:
1.Stainless steel (304, 316, etc.): corrosion-resistant, suitable for food and medicine
2.Brass, copper: electromagnetic compatibility filtration
3.Nickel, titanium alloy: high temperature resistance, acid and alkali resistance
4.Optional special coatings: such as PTFE coating, oil-proof, anti-static and other functional treatments
Size and Customization
Users can cut or customize filters into different shapes—such as discs, cylinders, or frames—to fit specific equipment or application needs.
The mesh count is only the starting point of the filter performance. Factors such as wire diameter, weaving method, material selection and size customization are also critical. At FUDAS, we analyze your usage scenario and recommend the most suitable specification combination, ensuring both filtration performance and cost-effectiveness.
Is there only one style of Mesh Filter?
There are many styles of mesh filter. According to our experience, customers usually bring drawings to find some customized filter meshes. The most common styles are
1.Wire mesh filters:Woven from metal wires; used for liquid, air, and fine particle filtration.
2.Sintered mesh filters:Sintered multi-layer mesh; ideal for high-pressure or backwashable filtration systems.
3.Perforated metal filters:Punched metal sheets; great for coarse or high-flow filtration applications.
Mesh Filter Applicable Scenarios
1.Food processing: used to separate impurities in juice and filter residues in cooking oil to ensure product purity and hygiene.
2.Plastic particles: used in the filtration process of molten plastic to remove impurities and ensure the purity and molding quality of plastic particles.
3.Mechanical parts: used in hydraulic systems and lubrication systems to filter metal chips and tiny impurities to protect the normal operation of precision parts.
4.Automobile filters: used in oil filters, air filters and other parts to remove particulate pollutants in the oil circuit and intake air to extend the life of the engine.
5.Oil and gas: used for particle filtration in downhole tools and pipeline systems to prevent blockage, improve operation efficiency and equipment safety.
6.Pharmaceutical industry: used for filtering liquid medicine, injection or intermediates, remove particles or pollutants, and ensure the purity and safety of medicines.
7.Water filtration: widely used in domestic water and industrial water treatment systems to remove suspended particles such as silt, rust, etc. to ensure water quality meets standards
Mesh Filter Post-care And Maintenance
1.Clean regularly
Develop a cleaning cycle based on the frequency of use and working environment. Use warm water or neutral detergent to rinse the mesh surface to prevent oil and particles from long-term adhesion and clogging of the mesh.If used for filtering oily substances, a special degreasing agent can be used for cleaning.
2.Avoid overloading
The filter has its designed maximum flux and pressure resistance range. Avoid using it under overload to prevent deformation, breakage or reduced filtration efficiency.
3.Check if the structure is deformed or corroded
Every time you clean or replace it, check if the mesh surface is damaged, deformed or corroded. Especially for sintered mesh or edging parts, if there are cracks or separation between layers, they should be replaced in time.
4.Proper storage
Unused filters should be kept dry, avoid heavy pressure, and away from corrosive gases or liquids to prevent oxidation, rust or deformation.
Although the filter has a simple structure, it plays an indispensable role in all walks of life. Whether it is the purity control of food processing or the system protection of industrial equipment, choosing the right filter type and specification is the key to ensuring product quality and stable operation of equipment.
