Removes what other filters miss
Ultra-fine filtration down to 0.0001 µm
Your family's water shouldn't just be filtered — it should be protected.
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.
Removal of
Silt
From natural soil and river sediment.

Rust
From old metal pipes.

Sand
From groundwater and pipe repairs.
200μm

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.
Removal of
VOCs
From industrial pollution, household cleaners, and pipe coatings.

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.

Lead
From old plumbing pipes and fittings.

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.
The way nature intended.

This system has become an indispensable part of my family life. It’s reliable, easy to use, and hyper fresh water.
- RPRahul P.Verified BuyerRated 5 out of 5 stars3 weeks agoBeen using for 9 months
I have been using this countertop filter for 9 months, and here’s my review. The system is easy to use, and the water tastes much better. It removes minerals that cause sediment, which is a common issue in Ballarat.
The only drawback is that the PAC filters don’t last for 12 month, but this may be due to the local water quality where I live. Overall, it has been a great purchase.
- LMLucy M.Verified BuyerRated 5 out of 5 stars4 months agoSave hundreds every year
Our office used to rely on bottled water (12L), which cost us around $1,700 a year. Because the team never cleaned the water cooler properly, we even started noticing algae building up inside it. We decided to switch to the Cascade system and placed it at the reception area. Since then, we’ve saved thousands every year. There’s no stagnant water anymore—water is filtered instantly when needed. It also completely eliminates the hassle of lifting, transporting, and storing heavy bottles, along with the risk of secondary contamination from long-term storage.
I would highly recommend Cascade as a replacement for traditional water dispensers in the workplace.

We bought our machine in late may and just got around to leaving the review. thanks h2o for making the process so seamless.
- DDiVerified BuyerRated 5 out of 5 stars7 months agoEyes were opened
A friend of mine recommended the water testing pen. So I ordered one. What i really liked from the beginning was that the staff send you a little video explaining how to use things. The videos are quite short but they are very practical. My water quality was 72 in North shore Sydney but I haven't been happy for some time. When my cascade arrived, it was very easy to set up. The video explains the whole process. I did the test again and my score was 99. Couldn't believe the improvement. It's amazing to think what we are taking into our bodies. Thanks so much H2O team.
