NanoFlow™ 5-stage filtration technology
NanoFlow™ 5-stage filtration technology
Delivering ultimate purity.
Our NanoFlow filtration effectively removes of 99% of over 1,000 contaminants—including PFAS, fluoride, lead, arsenic, chlorine, and microplastics—powered by 0.0001-micron reverse osmosis (RO) filtration.
Unlike traditional RO systems, our NanoFlow technology uses no chemical additives, no scale inhibitors, and no softening agents—just pure physical filtration. UV-LED sterilization helps maintain internal cleanliness and safety.
If you are searching for the gold-standard in water filtration, you have found the right place.

The taste of spring water
Taste is one of the main reasons many of our customers choose to invest in a H2O product.
The benefit of Cascade is that reintroduces beneficial minerals (calcium, magnesium, potassium, sodium, zinc) and raises water to a mildly alkaline pH—enhancing taste.
Some people describe the remineralisation as making the water taste "fuller", akin to spring water.

Stage 1 — Folded PP cotton pre-filtration
PAC composite
(folding PP cotton + high-density sintered carbon block)
(5μm)
The first stage of the PAC filter uses folding PP cotton, which offers far more surface area than standard flat PP cotton found in most filters. More folds = larger contact area + higher dirt-holding capacity.This means it captures more rust, silt, and fine particles, thus lasting longer and less clogging—giving your system a stronger and cleaner start.

Stage 2 — High-density sintered carbon block
PAC Composite
(Folding PP Cotton + high-density sintered carbon block)
This stage uses a high-density sintered carbon block to deliver cleaner and more consistent pre-filtration.
Its compressed, uniform structure captures finer chemical residue more effectively than loose carbon granules.
The result is better chlorine reduction, fewer VOCs, and a smoother, fresher taste — ensuring the RO membrane receives cleaner water for deeper purification.

Stage 3 — NanoFlow™ Reverse Osmosis
RO Filter (Reverse Osmosis)
(0.0001μm)
NanoFlow™ uses an upgraded 0.0001-micron membrane that removes up to 99.9% of dissolved impurities, delivering cleaner, safer water in every drop. It provides a faster flow and more stable purification — without relying on chemical scale inhibitors like many traditional RO systems. An automatic self-cleaning flush rinses the membrane regularly, maintaining peak performance and reducing build-up. The result is purer water, a longer-lasting membrane, and a more natural, healthy, and eco-friendly filtration process.

Stage 4 — Remineralise + Natural Alkaline pH 7+
AM filter (alkaline remineralisation)
Infused with naturally sourced minerals, this stage restores water to its true, original form—free from modern pollutants and enriched only with what nature intended.
Calcium, magnesium, potassium, sodium, and zinc dissolve gently to create a soft, crisp taste with a naturally weak-alkaline pH of 7.5+, closely matching the body’s own balance.Smooth, refreshing, and mountain-spring pure—it’s water as it was meant to be.

Stage 5 — UV sterilisation
UV chamber (99.9% sterilisation)
The UV chamber keeps purified water at its freshest — clean, bright, and crystal-clear. By neutralising bacteria and protecting the sealed tank from re-contamination, the purity you get at the RO stage is the purity you taste. Smooth, safe, and mountain-spring fresh—water held at its very best.
Five stages. One perfect taste
— clean, bright, and refreshingly pure,
just as water was before human pollution.

Absolutely love the Cascade! We’ve been using it for 3 weeks and the taste of the water is incredible. My kids now drink more water, and I feel better knowing it's alkaline and pure. Easy to use and looks great on our benchtop. A fantastic investment for our family.

So my first machine had an issue but then my second machine arrived with no problems at all. It took about 1 week to get everything sorted.

We used to boil tap water and let it cool for baby formula Now we just press a button and it’s done. So convenient
