Stage 1 — Folded PP cotton pre-filtration
PCB Composite — Front section
(Folded PP cotton + high-density sintered carbon block)
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
PCB Composite — Front section
(Folded PP cotton + high-density sintered carbon block)
Water continues through the front PCB section, now entering the high-density sintered carbon block.
This compact, uniform carbon structure removes chlorine and chemical residues more effectively than loose carbon granules.It also reduces VOCs and improves taste — while protecting the RO membrane, ensuring higher performance and longer lifespan.

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 — Post carbon + Remineralise (Option 1)
PCB Composite + AM — Rear section
(Remineralisation + coconut shell post carbon)
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 4 — Post Coconut Shell Carbon (Option 2)
PCB Composite — Rear section
coconut shell post carbon
The post-carbon stage uses high-density coconut-shell activated carbon, valued for its superior microporous structure compared to coal-based carbon.
More micropores = stronger adsorption and cleaner final taste.It effectively removes residual chlorine, VOCs, and any remaining odors, ensuring the final output tastes fresh, crisp, and naturally smooth — the perfect finishing touch before the water reaches your glass.
Four stages. One perfect taste
— clean, bright, and refreshingly pure,
just as water was before human pollution.

- ECEmily C.Verified BuyerRated 5 out of 5 stars7 months agoFresh water, great for skin!
I’ve been using the BlueSpring kitchen station at home, and I love it. Not only for cooking and drinking, but also for washing my face—and I’ve noticed how gentle and refreshing it feels compared to tap water. The installation was super easy, and it fits my faucet perfectly without any hassle. It has a strong flow, and the water comes out clean and clear. It gives me peace of mind knowing I’m using pure water on my skin. Definitely a great choice for anyone with sensitive skin.
- JWJames W.Verified BuyerRated 5 out of 5 stars8 months agoEasy installation
We don’t have much space under our kitchen sink, but installation was straightforward after watching an online video. It took less than an hour using just a wrench and drill.
It is helpful given the older pipes in our area, and a great alternative to buying and carrying bottled water. The potential savings on filter replacements are a big plus, and it comes with a long warranty. Highly recommended.
- SFScott F.Verified BuyerRated 5 out of 5 stars8 months agoupgrade from my old Zip
I only recently realised that Zip is more of a dispenser, while BlueSpring is an actual purifier. I ended up upgrading from my old Zip to a BlueSpring, and the difference is pretty noticeable. Once you taste the water, you realise the filtration is on a whole different level. My old Zip system took up almost the entire cabinet, while the BlueSpring only uses one shelf. I now have a lot more storage space, which is a really nice bonus.
- KSKate S.Verified BuyerRated 5 out of 5 stars9 months agoFast Installation
I live in a rural area of Victoria. I couldn’t find a local plumber or handyman to install it. I contacted H2O support, and their installer visited us on the third day, even after driving 250 km. They were incredibly helpful.
- GCGeorge C.Verified BuyerRated 5 out of 5 stars9 months agoI am impressed
I'll be honest, I thought we had really clean water here in Melbourne. I always thought that's what clean water tasted like and I've been fine with it. My wife said she could taste something in the water and I always thought she was a little crazy for it. Well, I was wrong... there is a different. Once this was installed (took about half a day since I had to extend and wire in an outlet under the counter and prep the countertop for the new faucet), I was really amazed that there was a difference... wow... just wow. I am convinced that this not only can work, and work well, but that my water that I THOUGHT was already perfect, wasn't. Super easy to use... installation takes a bit of work and may need a professional for many, but it's impressive.
