Watch
See Boon Tap in action.
Design & Engineering
The details you notice, and the ones you don't.
LED alerts display
A colour-coded alert bar and digit display on the purification unit, so one look under the sink tells you the system's status. No app needed.
Flexible installation
The purification unit fits under the counter or on the wall, whichever suits your kitchen.
Finish and colour
Choose the tap finish that fits your kitchen — three options, each one changing the look above the counter.
Glass front, thin profile
A slim, glass-fronted unit that tucks in without a second thought.
The Tap
An under sink water purifier for kitchens designed with intention.
Chlorine, dissolved solids, microplastics: none of them belong in a home you've designed this carefully. Boon Tap delivers purified, mineral-enhanced water from a stainless steel tap, thickened and milled to a finish that earns its place on the counter.
01
360° Full Rotation
A swivel that covers every angle of your sink. Fill a pot on the left, a bottle on the right, without repositioning.
02
One-Touch Toggle
One clean toggle to start and stop water. No twisting, no fumbling. Designed for one-handed use.
03
Solid Steel Body
SS 304 throughout, thickened and milled so the weight is in the metal itself — no plating to wear through.
04
Weighted Metal Base
A heavy, stable base that keeps the tap planted. No wobble, no drift: just precision where it sits.
The Unit
Slim body, glass face — built to be seen, not squeezed in.
A sleek glass-front unit that tucks away under your kitchen sink, or mounts to the wall when space is tight. Either way, it always keeps you informed.
01
Installation
Fits inside a standard sink cabinet or wall-mounts when cabinet space is limited.
02
Digit Display
Live TDS and other alerts, on the unit itself.
03
LED Alert Bar
Colour-coded bar signals when something needs attention.
04
Finish
Glass front panel.
05
Full Picture
Everything else lives in WaterAI™, live on your phone.
Finishes
Three finishes. One that goes with your kitchen.
The same solid stainless steel tap, milled once and finished three ways. 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.
Soul Silver
Limited EditionBright, classic steel. Matched to steel sinks and the hardware most Indian kitchens already run.
Matte Black
Limited EditionFor kitchens specified in black hardware. The tap disappears into the scheme instead of interrupting it.
Gunmetal Grey
The default. A deep, warm grey that sits easily against brushed appliances and stone counters.
Researched by Boon Labs
Removes what shouldn't be there. Keeps what should.
Municipal and borewell water across India carries chlorine, heavy metals, pesticide traces, and TDS up to 2000 PPM. UltraOsmosis™ removes what doesn't belong and returns what does — the same platform trusted by 400+ hotels, now under your kitchen sink.

UV ProGlow Filter™
Supporting protection and a final polish before the tap.
2 Year Warranty — best in segment.
The pre-filter holds more before it chokes
- Boon Tap
- Grooved surface holds dirt deep in the channels — flow stays open.
- Ordinary RO
- Smooth skin — dirt crusts on the surface and chokes flow early.
More membrane in the same shell
- Boon Tap
- Tightly wound membrane — more active surface in the same shell.
- Ordinary RO
- Loose winding — open gaps, less membrane on every litre.
Minerals from rock, not a factory pellet
- Boon Tap
- Mineral stones from natural deposits — slow, rock-like release.
- Ordinary RO
- Identical factory pellets — a fixed synthetic mix.
UV that reaches every drop
- Boon Tap
- Mirrored chamber — UV reflects wall-to-wall through every drop.
- In-tank UV
- One bare lamp in a tank — no reflection, light fades fast.
Key Benefits
Everything you want. Nothing extra.
Designed to bring purification, enhancement and intelligence into your kitchen without taking over the space.
Hidden system
All the performance, tucked neatly under your sink.
Beautiful tap
The only part you see is the part you want to.
Personal water
Mineral Enhancers and Water Profiles help shape water around your day.
Live intelligence
WaterAI™ keeps the important details visible.
Water Profiles
100% RO first. Minerals added after — never mixed in.
Every drop is fully RO-filtered first, then dosed with minerals through the WaterAI™ app: full enhancement when you move, a tuned pour for your morning coffee, or the balanced default in between.
Profile · 01
Active Mode
Full mineral enhancement for the moments that demand more.
Profile · 02
Daily Mode
Fully filtered, then dosed with balanced minerals. The default that fits most moments, from morning glass to fridge jug.
Profile · 03
Brew Mode
Mineral profile tuned for tea and coffee taste and clarity. Lower mineral load for cleaner extraction and truer flavour.

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.
Config · 01
Under the counter
Unit and tank sit together inside a standard sink cabinet. Nothing on the wall, nothing visible. The cleanest install.
Config · 02
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.
Config · 03
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.
