UltraOsmosis™ Filtration
Boon
Tap Under Sink Water Purifier
You chose every tile, every fixture, every finish. But the water your family drinks eight times a day? Boon Tap is the under sink water purifier that closes that gap —commercial-grade RO purification, mineral enhancement, and live water intelligence, hidden beneath your counter.
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.
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 ring on the tap signals water quality and system health 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.
Trusted by 400+ hotels and leading organisations worldwide
See Boon Tap in action.
An under sink water purifier compact enough to disappear. Smart enough to speak up.
The purification unit tucks away under your kitchen sink —or mounts to the wall when space is tight. Either way, it always keeps you informed.

What’s in your water
shouldn’t be a mystery.
Municipal water carries chlorine, heavy metals, pesticide traces, and TDS levels up to 2000 PPM —invisible, but present in every glass. UltraOsmosis™ was engineered by Boon Labs to remove what doesn’t belong and return what does. The same filtration platform trusted by 400+ hotels, now inside an under sink water purifier designed for your home.

The only under sink water purifier with Water Profiles.
Choose your Water Profile from the WaterAI™ app. Full minerals when you move. A tuned profile for your morning coffee. The default that fits everything in between. Your water adapts as your day does.
Active
Full mineral enhancement for the moments that demand more. All three enhancers, fully engaged.
Daily
Half mineral, half pure RO. The default that fits most moments, from morning glass to fridge jug.
Brew
Mineral profile tuned for tea and coffee taste and clarity. Lower mineral load for cleaner extraction and truer flavour.
Modes that look after your water when you’re not home.
Set once from the WaterAI™ app. Boon Tap handles the rest.
The default. Boon Tap flushes when it needs to, quietly, from the moment it is installed. Nothing to set, nothing to remember.
Every two to three hours. Because when there is a bottle on the counter and a small person in the room, reassurance is the product.
Every twelve hours, while you travel. The tap keeps itself honest so the first glass home tastes like the last glass before you left.
Performance you can see.

Designed around your kitchen. Not the other way around.
Every kitchen is built differently. 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.
