Difference Between PP Melt Blown Filter And PP Cotton Filter
| Feature | PP Cotton Filter Cartridge | PP Melt-Blown Filter Cartridge |
|---|---|---|
| Material | Polypropylene (PP) cotton fibers | Polypropylene (PP) melt-blown fibers |
| Filtration Precision | 5 microns | 1-5 microns (adjustable) |
| Structure | Loose, irregular fiber arrangement | Dense, layered fiber structure |
| Filtration Efficiency | Good for large particles | Better for fine particles |
| Dirt Holding Capacity | Moderate | High |
| Lifespan | 3-6 months (depending on water quality) | 3-6 months (depending on water quality) |
| Applications | Pre-filtration for household water purifiers | Pre-filtration for industrial and household systems |
| Cost | Lower cost | Slightly higher cost |
Summary of core differences:
1. Process and Structure
Meltblown filter element: A multi-layer gradient structure is formed through meltblown technology, which is loose on the outside and tight on the inside, filtering layer by layer.
PP cotton filter cartridge: mostly uniformly wrapped with fibers, relying on overall density filtration.
2. Performance differences
Melt blown filter element: High precision (1-5 microns), strong dirt holding capacity, suitable for fine filtration.
PP cotton filter: Low precision (5-20 microns), suitable for initial interception of large particle impurities.
3. Usage suggestions
If the water quality is poor or high-precision filtration is required (such as for direct drinking machines), priority should be given to using melt blown filter cartridges;
If only basic filtration (such as pre protection) is required, a lower cost PP cotton filter cartridge can be selected.
