Structural and Material Features
Core Components: Typically consists of a plastic housing, a removable filter screen, and a sealing mechanism; some inlet-mounted models feature a standard 1/2-inch (4-fen) threaded connection compatible with most household washing machine plumbing.
Common Materials: Filter screens often utilize food-grade PP or 304/316L stainless steel, while some lint-catching models use thickened nylon mesh with a resilient support frame, capable of withstanding 90°C hot water and prolonged exposure to standard detergents.
Manufacturing Details: Metal screens are produced via punching or weaving processes, ensuring uniform, burr-free apertures; nylon mesh edges are typically laser-cut or reinforced with high-strength stitching to prevent unraveling or snagging during use.
Filtration Performance Features
Graded Filtration Design: Most high-quality models feature a dual-layer structure; the outer layer with larger mesh pre-screens coarse debris (coins, buttons), while the inner layer of fine mesh (80–120 mesh) captures tiny lint and pet hair. Some inlet-mounted models offer 40-micron precision filtration to trap sediment, rust, and aquatic larvae.
Low-Resistance Flow: The mesh aperture ratio is optimized to ensure effective filtration without significantly impeding water flow, thereby avoiding issues such as slow drainage or excessive pressure drops during water intake.
Special Function Upgrades: Some high-end models incorporate an antibacterial silver-ion coating to inhibit bacterial growth on the filter and reduce odors inside the washing machine drum.
