Microplastics are tiny plastic particles that are smaller than 5 mc. They come from household items such as synthetic clothing, furniture and packaging. Every year, about 16% of the plastic produced in the world consists of textile fibers. In recent decades, production has grown by 6% and now equates to 60 million tons per year. Synthetic clothing is responsible for endless amounts of microfibers, which can even be found in drinking water.¹

Microplastics washed off from synthetic clothes contribute up to 35% of the plastic particles polluting our oceans. When we do laundry, an average of nine million microfibers end up in wastewater treatment plants that cannot filter them.² These unfiltered microfibers add to the plastic waste in the oceans.

Microplastics have been filling the oceans for years, but they also can be found indoors, especially within the dust on floors. Research shows that individuals may ingest microplastics at the rate of 11 particles per hour, and this occurs more through household dust and textiles than through consuming seafood, such as mussels. Researchers have found that the microplastics in wild mussels were low compared to those found in household dust.³

Until recently, research was focused on microfiber pollution through laundry washing. A recent study, however, shows how simply wearing synthetic clothes can pollute the environment. As many microplastic fibers are released into the air whenever we wear synthetic clothing as when we do laundry.⁴

To help reduce the amount of microplastics indoors:

• Choose products with less plastic packaging.

• Wear natural fabrics, such as cotton and wool, instead of synthetics, which are derived from petroleum-based chemicals.

• Wash synthetic clothing on a gentle cycle to decrease shedding.

• Use a HEPA air filtration system because it is effective at capturing microparticles.
