Comprehensive impurity filtration: The finemeshed filter captures impurities such as lint and fine fibers shed from clothes, preventing them from flowing into the drainage pipe and causing blockages. Protect drainage components: It blocks hard objects like coins and buttons from entering the drainage pump, reducing damage to internal parts of the pump body and extending the pump's lifespan. Smooth water flow passage: The filtration structure is designed to provide low resistance to water flow, enabling continuous and stable drainage without affecting the washing machine's normal drainage efficiency. Convenient cleaning and maintenance: The filter can be easily disassembled without tools; simply rotate or pull to remove it for regular impurity cleaning. Practical use scenarios: Household laundry with pockets that may contain coins or buttons, helping prevent pump damage and blockages. Washing bulky or lintprone fabrics (eg. fleece, towels) to keep lint from entering the drain. Routine maintenance to maintain smooth drainage and protect the washing machine's drainage pump.
