Hidden Exhaust Vents, Efficient Gravity Filling, Fast Funnel

Hidden multi-vents, no bubbles, no splashing
All exhaust vents are hidden inside the funnel, keeping the exterior smooth and clean, with no exposed holes, making it both attractive and tidy. There are sufficient exhaust vents, and the ratio of the exhaust cross-sectional area to the water inlet cross-sectional area is close to the optimal standard, allowing air in the bottle to escape smoothly. The filling process will not involve intermittent bubbling, and the water flow will always be in a full-pipe state, ensuring stability and no splashing.

Reject swirl gimmicks, direct flow is the real speed boost
Don't fall for those "viral fast funnels" that make water swirl; while the water may appear to flow smoothly, gravity is actually wasted on rotation, and the true forward momentum is diminished. This funnel allows water to flow straight down, dedicating all potential energy to forward movement. Coupled with ample venting, the flow rate is genuinely fast.

Slender and tall conical shape, more water head for powerful filling
With its slender and tall conical design, the internal water level can be higher with the same top opening size, exerting greater downward pressure. During filling, the gravitational potential energy is stronger, and the water flow has ample momentum, leading to shorter filling times for the same volume of liquid.

Precisely sized for common bottles
The outer diameter of the bottom opening is 21mm, fitting common cola bottles, mineral water bottles, beverage bottles, household glass oil dispensers, and more. It remains stable without wobbling or falling, meeting daily needs.
