A small tank runs out fast
During peak hours many people draw water continuously; a low-capacity tank can't heat or cool in time, so people have to wait.
Coway CORE CHP-671R
A 21-litre tank — enough water for a busy household or office.
The CORE CHP-671R is a hot, cold and ambient water purifier with a large 21.1L tank and a 5-stage RO system certified by WQA & NSF, with an LED touch display — ideal wherever many people draw water continuously.

Real Everyday Needs
When many people share the water, a small unit can't keep up
Offices, larger families and reception areas need a steady supply of hot and cold water all day — small tanks run out fast, force people to wait, and appliance care is easily forgotten.
Slow hot water, weak cold water
Low-power appliances struggle to hold a steady temperature when demand spikes.
Hard to keep clean and cared for
A shared appliance needs a clear cleaning and filter-replacement schedule with someone in charge.
Worried about source water quality
Inconsistent incoming water calls for an RO system that meets international standards.
