Product review (5 stars): Aluminum Mesh Wash Machine Lint Traps to attach to end of drain hose.
Best investment, especially for homes that have septic tanks to prevent lint from clogging up the system.  It is unbelievable how much lint is trapped by these clever aluminum traps.  Once the traps are dried they can be turned inside out and the lint removed and the traps can be reused several times.  Better to put lint in landfill then in an expensive septic system.
