Overweight Drain Screens -> Prevent Flooding: Many drain filters overflow with water (e.g. when emptying a cleaning bucket or shower) and free the drain. The result is constipation. Our drain strainers are not! The drain filter is very heavy, preventing water from penetrating. Innovative Two-Stage Pore Pattern: The advanced two-stage pore pattern allows for more efficient filtration performance (even for small dirt particles) at higher flow rates. This effectively protects your drains from clogs and odors and prevents water from accumulating. See for yourself! No scratches, no rust, no cracks: The drain filter is made of high-quality stainless steel, so it is rust-proof and even dishwasher safe. It is precisely stamped and ground so there are no sharp edges or burrs. This protects tooth enamel and prevents cuts when brushing. One size 7.5 x 7.5 cm - 20 g
