The tiny pollutants in our clothes are forcing us to look harder for, and think more carefully about, the ways humans have shaped the environment

Opening my washing machine at the end of a cycle is not something that generally fills me with excitement. But today it did, because doing so – I thought – would finally allow me to see and touch something I’ve been reporting on for years: synthetic microfiber pollution from apparel.
Instead, it illuminated something I already knew: my dog sheds a lot.
Multiple studies have shown synthetic fibers to make up the lion’s share of microplastics found in oceans, rivers and lakes, and clothes made from synthetics (polyester, nylon, and so on) are widely implicated as the source of that pollution. Microfibers, as the name implies, are tiny, so they can easily move through sewage treatment plants. Unlike natural fibers, such as cotton or wool, synthetic fibers do not biodegrade, and tend to bind with molecules of harmful chemical pollutants found in wastewater, such as pesticides or flame retardants. Studies have shown health problems among plankton and other small organisms that eat microfibers, which then make their way up the food chain. Researchers have found high numbers of fibers inside fish and shellfish sold at markets.
But I had recently received the Guppy Friend, a fiber-catching laundry bag made of a very fine nylon mesh developed by Alexander Nolte and Oliver Spies, surfing buddies and co-owners of Langbrett, a German retailer that sells outdoor apparel. The bag is designed to reduce the amount of fiber shed by garments in the wash and catch those that are shed. So, I was excited because this bag is supposed to make this invisible pollution visible.
I was relieved that my 15-year-old fleece jacket and month-old nylon leggings did not fill the bag with a mass of lint. But when I also discovered that only a teeny bit of fiber (and a lot of dog hair, each strand likely bigger than the microfibers found in waterways) in the bag after washing a bright blue Snuggie (hey, it was a gift), I became dubious about how effectively this device captures fibers.
