A pure purpose

Water filtration can be a bit of a balancing act: you want to filter water as thoroughly as possible, but you also want it to come out of your tap fairly quickly when you turn it on. Our whole-home systems provide ultra-fine filtration without limiting water pressure, but fluoride, PFAS, sodium, and other dissolved or microscopic impurities can slip through even the finest filters; the water is just moving too fast.

Our new Cirrus system solves this challenge in a new way: it leans all the way into the "thoroughness" side of the spectrum. We use a targeted 5-stage purification process on a single tap to make your drinking water as clean as possible without limiting water pressure in the rest of your home. Reverse osmosis removes those more persistent chemicals, giving you complete confidence in what's coming out of your tap.

Install standalone for dedicated protection
or alongside a whole-home system for
9-stage filtration.

How it works

The Cirrus system uses Reverse Osmosis (RO) technology to strip the tiniest impurities out of your drinking water, pushing it through a semi-permeable membrane that blocks anything larger than a red blood cell. The pores in this membrane are 5,000 times finer than a premium carbon filter, providing unparalleled protection for your home and family whether your water comes from the mains, a bore, or a rainwater tank. This is one of the only ways to effectively block dissolved substances like fluoride and sodium, and it filters harmful PFAS compounds more effectively than any cartridge system.

Coarse
filtration

STAGE 1

Sediment filters trap particles 14x finer than the width of a human hair, covering the initial heavy lifting to protect the more delicate components.

Fine
filtration

STAGE 2

A high-grade activated carbon block catches simple chemicals like chlorine and VOCs, taking them off the RO membrane’s plate.

Reverse
osmosis

STAGE 3.1

Water is pushed through the RO membrane, effectively stripping away anything that isn’t a water molecule: PFAS, fluoride, arsenic, sodium, calcium, chloramines, nitrates, the lot.

Water
storage

STAGE 3.2

Purified water slowly pre-fills the tank under your sink, ready to be used all at once rather than trickling through the purifier every time you turn on a tap.

Mineral
conditioning

STAGE 4

Reverse osmosis strips everything out of your tap water—including the good things. Cirrus uses a magnesium remineraliser to restore trace amounts of healthy minerals.

Carbon
finishing

STAGE 5

One last high-grade carbon block catches anything from the tank or remineraliser that might have slipped back into your water after purification, providing a pure, clean finish.
