In nine out of ten cases, that cloudy RO water is just tiny air bubbles. Think of it like opening a shaken soda—but way healthier. Your system repressurizes water through the membrane, and sometimes the dissolved gases (oxygen and nitrogen) get excited and form a brief, fizzy cloud.
Let that glass sit for a minute, and you'll watch the cloud magically disappear from bottom to top. It's like a mini science show on your countertop. No chemicals, no contamination—just microscopic bubbles partying and then leaving. How's that for a free show?
When Temperature Plays Tricks
Here's another plot twist: cold water holds more dissolved air than warm water. So if your RO system is feeding into a refrigerator line, you're practically inviting a bubble rave. Take a glass from the fridge, and the sudden temperature change makes those bubbles visible.
You can test this yourself! Fill a cloudy glass and set it on the counter. Hum a little tune while you wait. Within three minutes, it's crystal clear. This is not a defect—it's a feature of physics having a good time.
