Microplastics are everywhere—on our beaches, in our food, and increasingly, in our drinking water. While we often think of plastic pollution as an environmental issue, it’s now a concern that’s hitting much closer to home: our taps.
What Are Microplastics?
Microplastics are plastic particles less than 5 millimeters in size. They come from larger plastic waste that breaks down over time, as well as everyday sources like synthetic fabrics, personal care products, and industrial runoff.
How Do Microplastics Get Into City Water?
There are several ways these tiny particles make their way into municipal water supplies:
-
Runoff from landfills and street waste
-
Fibers shed from the laundry
-
Industrial waste
-
Incomplete filtration at wastewater treatment plants
Are Microplastics Harmful?
Research is still ongoing, but early studies raise concerns. Microplastics may carry chemicals and harmful bacteria, and there’s evidence that they can pass through the body’s defenses and into the bloodstream.
While the long-term health impact isn't fully known, many experts recommend reducing exposure, especially regarding drinking water.
How Can You Remove Microplastics from Your Tap Water?
The good news: some filters can help. According to recent findings, the most effective filters for reducing microplastics include:
-
Activated Carbon filters (especially multi-stage systems)
These filters can significantly reduce not just microplastics, but also other contaminants commonly found in city water.
