Microplastics in Water
What You Need to Know and How to Avoid Them
Let’s talk about something that might just ruin your next sip of water—microplastics. These tiny, invisible invaders are lurking in our drinking water, bottled water, and even the air. And while they may be small, the potential consequences for our health and the environment are anything but.
So what exactly are microplastics? How do they get into our water? And most importantly, what can we do about it? Let’s break it down and, more importantly, find some real solutions so you don’t have to second-guess every glass of water you drink.
What Are Microplastics and Why Should You Care?
Microplastics are tiny plastic particles—usually under 5mm in size—that come from the breakdown of larger plastic items, synthetic fibers from clothing, industrial waste, and even personal care products like exfoliating scrubs. These microscopic bits make their way into our rivers, lakes, and oceans, ultimately ending up in our drinking water. Studies have found microplastics in tap water, bottled water, and even deep-sea environments where humans have never set foot.
While research is still ongoing, there are real concerns about the impact of consuming microplastics. Scientists believe they may disrupt hormones, cause inflammation, and expose us to toxic chemicals that leach from plastics. Some studies suggest they could even contribute to long-term health issues, though more research is needed.
How Do Microplastics End Up in Your Water?
You might be thinking, I drink tap water from a clean source, so I’m fine, right? Unfortunately, not so much. Microplastics infiltrate water supplies in a few key ways:
Breakdown of Plastics – Plastics don’t just disappear; they slowly degrade into smaller and smaller particles that end up in groundwater, rivers, and lakes.
Bottled Water Contamination – Bottled water has been found to contain more microplastics than tap water, likely due to the plastic packaging itself shedding particles.
Synthetic Clothing – Every time you wash synthetic fabrics like polyester or nylon, microfibers are released into wastewater, which then enters waterways.
Industrial Pollution – Factories and industries using plastic materials often release microplastics into water systems.
Atmospheric Fallout – Believe it or not, microplastics are in the air and can settle into open water sources or even directly into your glass if left uncovered.
How to Filter Out Microplastics from Your Drinking Water
Now for the good news: there are ways to reduce your exposure. While microplastics are tiny and tricky to remove, certain filtration systems have proven effective. Here are the best ways to filter them out of your drinking water:
1. Reverse Osmosis (RO) Systems
Reverse osmosis is one of the most effective filtration methods for removing contaminants, including microplastics. It uses a semi-permeable membrane to filter out particles as small as 0.0001 microns. Given that microplastics range in size from 1 micron down to nanometers, an RO system can significantly reduce their presence in drinking water.
Why I recommend it:
✔️ Removes nearly all contaminants, including bacteria and heavy metals.
✔️ Works well for both tap water and well water.
✔️ Provides incredibly clean-tasting water.
Downside:
❌ Can be expensive to install.
❌ Wastes some water in the process.
2. Activated Carbon Filters
Activated carbon filters, like those in many pitcher filters or under-sink systems, can trap some microplastics, especially those on the larger end of the scale. These filters work by adsorption, capturing particles and chemicals in their porous structure.
Why I recommend it:
✔️ Affordable and easy to install.
✔️ Reduces other contaminants like chlorine and pesticides.
✔️ Available in various formats (pitchers, faucet attachments, under-sink systems).
Downside:
❌ Not as effective for the smallest microplastics.
❌ Requires frequent filter changes to maintain efficiency.
3. New Microplastic-Specific Filters
There are now specialized water filters designed specifically to remove microplastics. These filters use advanced nanotechnology, electrostatic charges, and specially designed membranes to trap even the tiniest plastic particles. Some brands have developed filters that claim to remove up to 99% of microplastics from drinking water, making them a cutting-edge solution for those serious about reducing their exposure.
Why I recommend it:
✔️ Specifically designed to target microplastics, making them highly effective.
✔️ Available in countertop and under-sink models.
✔️ Some models integrate with existing filtration systems for extra protection.
Downside:
❌ Can be costly compared to standard filters.
❌ Some brands are still refining their technology, so research is necessary before buying.
4. Distillation
Distillation involves boiling water, collecting the steam, and condensing it back into liquid form, leaving contaminants behind. Since microplastics don’t evaporate, they’re left in the boiling chamber, making distilled water one of the cleanest options available.
Why I recommend it:
✔️ Removes microplastics, bacteria, heavy metals, and more.
✔️ Provides ultra-pure water.
Downside:
❌ Slow process.
❌ Requires a lot of energy to operate.
❌ Some minerals in water are also removed, which could affect taste.
Microplastics in water are an unsettling reality, but there’s plenty we can do to limit our exposure. Investing in a solid filtration system, making mindful choices about plastic use, and supporting policies that reduce plastic pollution can all make a difference.
Water should be refreshing and hydrating—not a source of invisible plastic particles. By taking action now, we can protect our health and ensure cleaner, safer water for the future.
