Washing machine filter prevents microfibers from going down the drain

Protecting Georgian Bay’s Water

In Georgian Bay Forever's Divert and Capture project, we are installing 100 washing machine filters (Model: 160 Filtrol from Wexco) in Parry Sound households. We are partnering with Lisa Erdle, a student from the Rochman Laboratory at the University of Toronto. She will be sampling water from the effluent of the Parry Sound wastewater treatment plant, and measuring the impact these filters are having on the reduction of microfibers that flow into Georgian Bay.
A little background...

According to Capturing microfibers – marketed technologies reduce microfiber emissions from washing machines 1 ( McIlwraith at. al), the Lint LUV-R (a filter similar to the FIltrol 160) captured 87% of micofibers in the wash by count.

Microfibers come off your clothes during laundering, and since most of your clothes are likely made from synthetic materials many of them are plastic. These tiny strands of plastic (less than 5 mm) can be as high as 700,000 per wash load depending on the amount and the synthetic materials in the wash (Napper and Thompson) 2.

In the Capturing microfibers 1(McIIwraith et.al) published research paper, 90,700 to 138,000 fibers are estimates based on washing one synthetic blanket. Some further 'downstream estimates' show some potentially very alarming consequences.

    "Most of these fibers will travel with wastewater to a WWTP to be treated. Studies suggest that 83–99.9% of microplastics are captured in the sludge of a WWTP (Carr et al., 2016; Dris et al., 2015; Talvitie et al., 2017), with the remaining emitted to the aquatic environment via final effluent. If 99% of the 23 to 36 trillion microfibers are captured in the sludge, then up to 234 to 356 billion could be released directly into lakes and rivers annually based on our data and calculations. If the sludge is land applied, some of the remaining ~23–35.5 trillion could also be released into the environment."3

We all need to do things differently to protect our freshwater - from changing our fashion choices away from synthetic materials and clothes that have a short-life span, to decreasing our frequency of clothing purchase, to reducing the number of washing loads we do, to installing filters on our washing machines.

Microplastics from a blanket

Georgian Bay Forever (GBF), thanks to our funders and partners, aims to build on the microfibers research and test a filter solution in the field - with real households - in a Parry Sound Field Study we are calling Divert and Capture. When complete, in about 2.5 years, these results will be shared with stakeholders, manufacturers , and the public to influence change in our habits that are currently leading to the build-up of plastic in our freshwater.

  • Read more about microplastics and this project at this link, "Microplastics Impacts" .

    • What can you do:

    1. Buy a filter for your washing machine. There are different filters on the market. It's also important for septics.
    Read why at this link.
    U of T Rochman lab tested 2 outside washing machine filters. The Lint Luv'r and the Wexco FIltrol 160, and found they were 87 to 89% effective at capturing fibers. Both are available in Canada if you search online (if you buy outside of Canada, you will be subject to fees if you import them). Last time we looked they cost anywhere from $180 to around $220 BEFORE installment and shipping. For the Divert and Capture project, GBF is installing the Filtrol 160 from Wexco into Parry Sound residences for our filter study.

    2. Until better solutions and more research is completed on microfibre and microplastics impacts - general tips include avoiding over consumption of clothing and particularly synthetic clothing, decrease your laundering, and minimize one-use plastic like bags and coffee cups and lids.

    3. Undertake clean-ups of your favourite shorelines in Georgian Bay and dispose of the litter in the appropriate manner. You're helping water quality for the plants and animals in the Bay and restoring shoreline beauty.
