| Porous Powder Sintered Filter | Sintered Mesh Filter | |
| Material & Structure | The pore structure is irregular and complex Formed by high-temperature sintering of metal powder |
Has a regular layered structure Formed by sintering multiple layers of metal wire mesh |
| Precision | Up to 0.1μm High-precision filtration |
1-100μm Coarse or medium filtration |
| Porosity | controlled by the powder particle size, and is crisscrossed |
Determined by the mesh size and the number of layers of the wire mesh, and is uniformly distributed |
| Breathability | High flow resistance, but strong dirt-holding capacity, suitable for long-term continuous filtration |
Low flow resistance, high air permeability and high flow rate |
| Strength | High compressive strength, but more brittle, not easily deformed |
Low compressive strength, but good toughness, can be folded or welded |
| Filtering Mechanism | Mainly deep filtration, allowing impurities to penetrate deep into micropores |
Mainly surface filtration impurities are easily cleaned |
| Application | High-precision filtration (e.g., pharmaceuticals, catalyst recovery) and high-temperature gas treatment |
Liquid/gas filtration for high-temperature, high-pressure, or corrosive environments |
