In a gravity system, water flows through the filter from a higher altitude using its own gravity and pressure, thus achieving the best filtration effect

This outdoor filter uses natural coconut activated carbon to reduce bad taste, odor, rust, sediment, heavy metals, spore cysts, and other harmful substances. It has a 98% reduction rate for fluorine and a 98.95% reduction rate for residual chlorine, resulting in better-tasting water after filtration.

They have a lifespan of 3000 gallons. The Fluorine filter can effectively reduce fluoride and arsenic and has a lifespan of 1000 gallons. It can adsorb residual heavy metal ions.

Gravity systems are energy-efficient and cost-effective. They don't use motors, which ensures that the electrical costs are much lower.
