How a Tiny Seal Makes a Big Difference in Your Water Filter
Ever wonder why some water filter pitchers work smoother than others? The secret lies in a smartly engineered floatable body with a friction-controlled seal.
The Role of the Seal in Water Filtration
Inside the pitcher’s sleeve, the floatable body holds the filter in place. But what keeps it from wobbling or getting stuck? A protruding seal around the floatable body interacts with the sleeve’s sidewall in two key ways:
1. Higher Friction When Rising: As water fills the pitcher, the floatable body moves up, and the seal presses firmly against the sidewall, preventing sudden jumps.
2. Lower Friction When Lowering: When pouring water, the seal’s grip loosens just enough to let the filter descend smoothly.
Why Traditional Pitchers Burp (And This One Doesn’t)
Older designs allow air to get trapped, forcing it to escape with a loud "burp." But with this auto-retracting floatable body, water flows seamlessly, and air escapes gradually—no noise, no mess.
Key Takeaways
🔹 Controlled friction ensures stability.
🔹 No disruptive air bubbles mean consistent water flow.
🔹 Better user experience with silent, smooth operation
This small but crucial engineering detail makes a huge difference in everyday use!
