Did you know that laundry is the #1 source of microplastic pollution? With every load of laundry, millions of tiny plastic particles come off our synthetic clothes, down the drain, and into our waterways. In this episode, we speak with Max Pennington, Co-Founder and CEO of CLEANR. Max and his partners may have the solution to plastic pollution we've been looking for. His Cleveland-based company recently launched a patented filter that captures up to 90% of all microplastics from your washing machine before they enter the drain. Max developed this breakthrough technology with fellow engineering students Chip Miller and David Dillman within the Sears think[box], an innovation lab at Case Western Reserve University. 

Their VORTX filter design was inspired by the gills of fish, specifically by the way manta rays and basking sharks filter feed. This biomimicry-based design creates a vortex that keeps the filter from clogging while effectively capturing harmful microplastics. These young entrepreneurs recently launched their company CLEANR, with a filter that easily attaches to any washing machine. 

Hear how Max and his partners plan to bring this technology to market. Their CLEANR filter is currently available as an external washing machine attachment for $299. The ultimate goal is to integrate it directly into washing machines, making microplastic filtration as standard as lint traps in dryers. The company is also exploring applications beyond laundry, including whole-home water filtration to protect against microplastics entering our bodies through drinking water. 

Capturing microplastics before they enter our waterways could be a real game-changer, especially if supported by legislators and policymakers. Would they go for it? Max thinks so. Already, five U.S. states have introduced legislation requiring microplastic filters on washing machines, with similar momentum building in Europe. 

With synthetic fibers from our clothing accounting for 35% of all plastic pollution in our water systems, the implications extend far beyond environmental protection. Recent studies have found alarming connections between microplastics in the human body and increased risk of heart disease and other health conditions. These plastic particles have been discovered in human blood, brains, and even the placentas of newborn babies. With an estimated 22 million pounds of microplastic particles entering the Great Lakes annually, the Cleaner team aims to make Cleveland "ground zero in the fight against microplastic pollution," tackling it one laundry load at a time.
