Tap UF Under Sink UF Water Purifier
Your water is already low in dissolved solids: it’s the bacteria, cysts, chlorine and sediment that don’t belong. Boon Tap UF is the under sink water purifier that removes them through a 0.01-micron UltraFiltration™ membrane, keeps the natural minerals your water already carries, and wastes not a single drop, hidden beneath your counter.

An under sink water purifier for kitchens designed with intention.
Chlorine, bacteria, cysts, microplastics: none of them belong in a home you’ve designed this carefully. Boon Tap UF delivers purified, naturally mineral-rich water from a stainless steel tap, thickened and milled to a finish that earns its place on the counter.
A swivel that covers every angle of your sink. Fill a pot on the left, a bottle on the right, without repositioning.
One clean toggle to start and stop water. No twisting, no fumbling. Designed for one-handed use.
A colour-coded LED alert bar and a digit display show live TDS and other alerts at a glance. No app needed: just look.
A heavy, stable base that keeps the tap planted. No wobble, no drift: just precision where it sits.
Three finishes. One that goes with your kitchen.
The same solid stainless steel tap, milled once and finished three ways: Matte Black, Gunmetal Grey, and Steel Silver. Matched to matte black hardware, brushed appliances, or classic steel sinks, so the tap reads like it was specified with the kitchen, not added after.
Trusted by the world’s leading organisations

Compact enough to disappear. Smart enough to speak up.

What’s in your water
shouldn’t be a mystery.
Municipal and treated water across India can still carry chlorine, bacteria, cysts, sediment and turbidity: invisible, but present in every glass. UltraFiltration™ was engineered by Boon Labs to catch them at a 0.01-micron hollow-fibre membrane while letting the natural minerals your water already carries pass straight through, with zero water sent to the drain. The same filtration platform trusted by 400+ hotels, now under your kitchen sink.

Designed around your kitchen. Mount it on the wall, or tuck it below the sink.
A sleek glass-front unit that earns its place wherever it sits. Every kitchen is built differently, so Boon Tap installs three ways: each one clean, each one out of sight to anyone who isn’t looking.
Under the counter
Unit and tank sit together inside a standard sink cabinet. Nothing on the wall, nothing visible. The cleanest install.
Wall-mounted, tank below
The purification unit mounts to the wall. The tank sits beneath. Works when cabinet depth is limited but wall space is open.
Wall-mounted, tank on top
Both unit and tank mount to the wall, stacked. Frees the cabinet entirely, ideal when under-sink space is spoken for.
