SHOWERHEAD DIFFUSION

A standard downstem pushes air through a single open stem into your water. A showerhead splits that into six points of contact for more surface area, finer bubbles, and smoother hits. Same water, different experience.

WIDER SLITS. FASTER CLEARS.

Traditional showerhead slits are narrow. They diffuse well but may increase drag. The Hi-Flo's slits are more than twice the width, so air moves through with less effort. Faster clears, easier draws, and slits wide enough that they don't clog in the event of material fall through.
