Understanding Product Net Weight & Durability.

While often overlooked, weight is a reliable proxy for build quality, pump robustness, and tank thickness.

1Heavy-Duty Components

Heavier units typically indicate larger, more powerful booster pumps and thicker food-grade plastic casings.

A full water tank adds roughly 1kg per liter. A 10L unit can weigh over 20kg when full. Mounting brackets must be high-tensile steel.

Desktop models need sufficient weight to remain stable on countertops without vibrating during the RO pump cycle.
