Now here is where it gets funny. The distilled water inside the jug is pristine. It’s been through a rigorous chemical boot camp. But the plastic jug itself is the wild card.
Imagine you’ve just finished a 5K run, and you’re covered in sweat. You are, biologically, very pure. But then someone hands you a T-shirt made of sandpaper. You’re still pure, but the shirt is shedding fibers all over you. That’s your water bottle.
Plastic jugs, especially if they’ve been sitting in a hot warehouse or baking in your car, can leach tiny plastic particles into the water over time. It’s not the distillation process failing; it’s the storage process being a slacker.
The Real Villain: Time and Sun
Your distilled water is a saint until it gets locked in a plastic prison for six months. The sun’s UV rays and heat are like kryptonite for plastic. They break down the polymer chains, and those little microscopic bits take a swim.
So, does store-bought distilled water have microplastics? Probably a little, but more from the packaging than from the water itself. It’s like buying organic vegetables wrapped in a plastic bag—you’re getting some unintended extras.
But here’s the kicker: compared to tap water or bottled spring water? Distilled is still the cleanest option by a landslide. Tap water can have a whole zoo of contaminants, including microplastics from pipes and treatment plants.
