Do Water Filters Remove Microplastics from Drinking Water?

Every time you take a sip of water, you could be ingesting tiny pieces of plastic. These ‘microplastics’, which come from synthetic fabrics, industrial waste, and everyday plastic products, have been detected in tap water, bottled water, and even the air we breathe. While the long-term health effects are still being studied, many people are asking: do any water filters remove microplastics​?

Let’s explore the facts.

What Are Microplastics and Why Are They in Our Water?

Microplastics are tiny plastic particles less than 5 millimetres in size. They come from different sources, including:

• The breakdown of larger plastic waste: Plastics don’t biodegrade; they break into smaller and smaller fragments over time.

• Synthetic clothing: Every time you wash clothes made of polyester or nylon, microfibres are released into the water system.

• Personal care products: Some exfoliating scrubs, toothpaste, and cosmetics contain microbeads, which are rinsed down the drain.

• Industrial processes: Factories release plastic particles into the air and water during manufacturing.

But how do these plastics end up in your tap water? Researchers have found that microplastics enter drinking water supplies through contaminated rivers, lakes, and reservoirs. Water treatment plants aren’t always equipped to filter out these tiny particles, meaning they can pass through into your household tap.

Recent research highlights just how widespread the problem is. A study by Orb Media found that 83% of global tap water samples contained microplastics, with contamination rates as high as 94% in the United States. Another study detected microplastics in bottled water at twice the concentration found in tap water. This means that whether you drink tap or bottled water, you could be ingesting tiny plastic particles every day.

The Risks of Consuming Microplastics

If microplastics are so common, does that mean they’re safe? Not necessarily. Scientists are still studying their long-term effects, but early findings raise concerns.

• Microplastics may disrupt hormones: Some plastics contain endocrine-disrupting chemicals like BPA and phthalates, which can interfere with the body's hormone system.

• They can absorb toxins: Microplastics act like sponges, attracting heavy metals, pesticides, and harmful chemicals, which can then enter the body when consumed.

• They may accumulate in the body: While larger microplastics may pass through digestion, smaller nanoparticles could penetrate organ tissues, potentially leading to inflammation or other health effects.

In 2022, researchers found microplastics in human blood for the first time, suggesting they may circulate throughout the body. Other studies have detected plastic particles in lung tissue and even placentas, raising concerns about potential long-term health risks.

How Water Filters Can Remove Microplastics

The good news? The right water filtration system can significantly improve the purity of your drinking water. But how do water filters remove microplastics​?

Water filters use different technologies to remove contaminants based on size, charge, and chemical properties. Because microplastics vary in size, multiple filtration methods can be effective:

• Reverse Osmosis (RO) Filters: These systems use a semi-permeable membrane that blocks particles as small as 0.0001 microns, making them one of the most effective solutions for removing microplastics.

• Activated Carbon Filters: While primarily designed to remove chlorine, taste, and odours, high-quality carbon filters can also trap some microplastics, especially larger particles.

• UV Filtration: Ultraviolet purification is great for killing bacteria and viruses, but it does not physically remove microplastics. However, when combined with RO or carbon filtration, it improves overall water purity.

If you're looking for a reliable way to remove microplastics, AquaSafe offers several high-performance options:

• Reverse Osmosis Filters: The gold standard for eliminating microplastics, heavy metals, and other contaminants.

• Whole House Filters: Ensures clean water from every tap, not just your kitchen sink.

• Undersink Filters: A convenient option for targeted filtration without the need for bulky equipment.

The Best Water Filters for Removing Microplastics

So, which water filtration system is best for tackling microplastics? Here’s how different methods stack up.

Frequently Asked Questions About Microplastics and Filtration

Can standard home water filters remove microplastics?

Most basic filters, like pitcher filters, are not designed to catch microplastics. High-quality reverse osmosis and advanced carbon filters are the best choices.

Which type of water filter removes the most microplastics?

Reverse osmosis is the most effective, removing over 99% of microplastics due to its ultra-fine filtration membrane.

Do bottled water brands contain microplastics?

Yes! Studies have found microplastics in many bottled water brands, sometimes at higher levels than in tap water.

Are microplastics in water harmful to human health?

While research is ongoing, microplastics may pose risks due to their ability to carry toxins and disrupt hormones.

Take the Next Step Towards Microplastic-Free Water

Microplastics in drinking water are a growing concern, but you don’t have to be exposed to them. Investing in a high-quality water filtration system means you and your family can enjoy cleaner, safer water.
