You bought the glass bottle because it felt cleaner, more pure somehow. No microplastic exposure, no chemical aftertaste, no guilt. Just water in a smooth, heavy vessel.
But here’s the twist: that crystal-clear bottle might be hiding more than just spring water. New research shows that microplastics in bottled water are more common than you think. And glass bottles may be the worst offenders.
Microplastics: A Small Threat with Big Implications
Before we get into the details, it’s worth understanding what microplastics actually are because they’re everywhere. They’re in our food, in the air we breathe, and now even in the wine and water we drink.
Smaller than five millimeters, microplastics are tiny shards of plastic, no bigger than a flea’s whisker or a grain of sand. They slip into our water and food like silent ghosts, too small to see but impossible to ignore.
Microplastics have been linked to:
- Inflammation and immune disruption
- Hormonal imbalance
- Potential organ damage
- Possible accumulation in brain and placenta tissue
You can’t see them, but they might be wreaking havoc inside your body.
A New Study Shatters the Glass Bottle Illusion
Studies have shown the widespread contamination of microplastics from plastic containers, food packaging, and more. But a new French study published in the Journal of Food Composition and Analysis found something surprising.
Glass bottles, long thought to be the gold standard of beverage container purity, had 5 to 50 times more microplastics than plastic or metal containers.
Where’s it coming from?
Not the container itself. Not the water. But the cap.
Painted metal caps, sealed tight and screwed on with factory force, release tiny plastic particles directly into your drink. These particles come from the decorative liners or painted bottle caps that rub off from the friction and fall into your beverage when you open it.
Study Snapshot
- On average, 100 microplastic particles per 33.8 fluid ounces (or one liter) were found.
- Painted metal bottle caps were the primary contaminant source.
- Rinsing or blowing off bottle caps before opening reduced particle count by up to 60%.
- Microplastic levels varied depending on how long bottles were stored and handled.
While microplastics were found in different types of beverages, some drinks had higher levels than others.
So, Which Glass Bottled Drinks Should You Be Wary Of?
If you’re sipping from a glass bottled beverage like beer or soda, you may be getting more than bubbles.
Most Affected:
- Glass bottle iced tea
- Lemonade in glass bottles
- Glass soda bottles
- Beer bottles
- Even glass water bottles showed elevated levels
- Smaller amounts were found in wine from bottle seals
Caps coated with polymer-based paints or linings were the worst culprits. The irony? Glass bottles are often marketed with labels like “pure,” “natural,” or “eco-friendly.” But the reality is they may be contributing more microplastics than plastic bottles.
Skip the Bottle: Choose RO Filtered Water Right from Your Tap
Most municipal water treatment plants weren’t built to catch microplastics. Their filters and processes remove sediment, bacteria, and larger particles. But those tiny plastic fragments? They often pass right through.
Glass bottles of water aren't a guaranteed solution either. To truly protect yourself, you need a filtration system that works on a microscopic level.
If you’re feeling overwhelmed and just want to know how to remove microplastics from water, reverse osmosis (RO) does exactly that. It pushes water through an ultra-fine membrane with pores just 0.0001 microns wide.
How it works:
- Water is pushed through a 0.0001-micron membrane
- Microplastics, PFAS, fluoride, and heavy metals are left behind
- What comes out is crisp, clean, and contaminant-free
Most microplastics are between 1 and 100 microns, so RO doesn’t just reduce them. It removes them entirely, making RO systems one of the most effective water filters for removing microplastics.

Everyday Ways to Reduce Your Microplastic Load
Protecting your family from microplastic contamination doesn’t have to be complicated. In addition to investing in a home RO system, there are a variety of ways to avoid microplastics.
Here are some simple steps you can take:
- Rinse or blow off bottle caps before opening (can reduce plastic flakes by up to 60%)
- Use filtered water (especially RO) for drinking, cooking, and baby formula
- Switch to stainless steel or glass storage containers
- Avoid ultra-processed foods, which often contain plastic particles from machinery
- Avoid plastic packaging as microplastics can leach from plastic materials during storage and handling.
Small changes add up. Every swap you make helps lower your exposure and protect your family’s health long-term.
The Bottom Line: Clean Water Starts at Home
In a world where even clean water carries invisible risks, your best defense isn’t guessing, it’s filtering.
The Aquasure Premier Elite Series RO System makes that easy. No guesswork. No gimmicks. Just clean, microplastic-free water at the turn of a tap.
