The Filtrol 160 from WexCo Environmental is the first washing machine lint trap capable of capturing microscopic fibers and keeping them out of the septic systems. It also filters out hair, microplastics, pet hair, concrete particles, metal shavings, and sand, all of which, like fabric fibers, can accumulate in a septic drainfield, drastically reducing its ability to help filter the wastewater that is deposited in the septic tank. 888-983-2447; www.septicsafe.com.
