Filtration
Filtration
Activated Carbon – Reduces chlorine, PFAS, and common chemical residues that affect taste and odor.
KDF – Helps reduce heavy metals and residual chlorine while supporting long-term system performance.
PP Membrane – Captures fine particles and protects the filtration system over time.
Mineralization – Natural mineral stones are used to refine taste after filtration. No distilled feel. Just water that tastes right.
What Our Customers Say
Mari
After 7 years of living in Lisbon where water quality is below average, it’s safe to say this filter has finally changed that! We can now give our baby water from the tap and what a relief it is to be able to skip the water bottles.
Easy to install, delicious water taste and the customer service we received was outstanding!
Andrea Roth
I was looking for a water filter that doesn't require changing of the existing faucets and that would not only filter the water but remineralise it as well. By chance I found PJURE and was immediately hooked as it met my needs and only requires to renew the filter once a year. Extra bonus - beautiful and durable design and installation without any need for drilling holes. The water tastes better than with my previous filter system and the water flow is the same as before using the filter, not the slow flowing drizzle that I once had with another under the sink filter system.
Filipa Sanches Carrilho
Very good material! The water has a much better taste, and it is really easy to install. The customer service team is also very friendly and helpful. We are super happy with this subscription.
Advanced 3 + 1 Filtration Technolody
Column
Certified to NSF/ANSI 53, and 42 standards for the reduction of PFAS (PFOA/PFOS), chlorine, and the smallest class of particles (≥0.5 micron).

Independently tested to NSF/ANSI 53, and 401 standards, to reduce lead, pharmaceuticals, VOCs, and other emerging contaminants.
How Pjure filters your tap water. Layer by layer
PP membrane
Our PP membrane captures fine sediment and protects water clarity.
It blocks microplastics, rust, and particles ≥5 μm before they reach the main filter stages.
By removing large contaminants early, it improves flow, extends filter life, and keeps the water crisp and clean.
Activated carbon block
A high-density activated carbon block removes chlorine, PFAS, chemical residues and improves taste & odor.
This stage targets the most common household contaminants and ensures fresh, clean-tasting drinking water.
Its ultra-absorptive structure traps harmful organic compounds before they pass through.
KDF (Copper–Zinc Alloy)
KDF provides powerful redox protection against heavy metals like lead, controls bacterial growth and reduces pesticides.
It also delivers enhanced chlorine reduction, strengthening the performance of the activated carbon stage.
This layer ensures safer, more stable water quality over time.
Calcite & Maifanite Mineralization
This stage uses natural calcite and maifanite to reintroduce essential minerals like calcium and magnesium for cleaner, smoother-tasting water. Calcite helps bring slightly acidic water back toward a neutral balance, while maifanite releases trace elements that enhance taste and support everyday hydration.

What does it remove and add back?
What does it remove and add back?
Removes
- Bacteria, parasites & cysts
- Chlorine, chloroform & VOCs
- Lead & heavy metals
- PFAS & microplastics (down to ~1 μm)
- Pharmaceutical & hormone residues
- Sediment, turbidity & bad taste/odor
Adds back:
- Essential minerals (Ca, Mg, K) for smooth, natural taste
- Natural electrolyte balance for hydration
- Supports body function & immunity
By removing acid-forming contaminants and restoring essential minerals, PJURE produces naturally pH-balanced water — around 7.5.
What is the water pressure and flow rate?
What is the water pressure and flow rate?
The flow rate is about 3.8 liters per minute, tested under 4.1 bar, which is typical water pressure in most European homes.
To put it simply, your existing water pressure stays the same with a steady water stream. No pressure drop, no weak trickle.
Your tap will work just like before, only better! Now with clean, mineral-rich water coming out.
Whats the difference between Pjure and Reverse Osmosis?
Whats the difference between Pjure and Reverse Osmosis?
Reverse Osmosis (RO) pushes water through an ultra-fine membrane using high pressure. It removes almost everything — including contaminants and the natural minerals (like calcium and magnesium) that the body actually needs. The result is extremely pure water, but often too pure: it can become slightly acidic (pH below 7) and less hydrating.
PJURE, on the other hand, uses a 4-layer filtration system:
- 3 layers to purify (removing bacteria, heavy metals, VOCs, chlorine, etc.)
- 1 final layer to add minerals back in – helping the water reach a natural, slightly alkaline pH of ~7.5, which supports taste, hydration and overall wellbeing.
Unlike RO, PJURE doesn’t require electricity or a bulky pressure tank, making it compact and easy to install under any sink — in just 10 minutes.
Do I need a plumber?
Do I need a plumber?
No – it’s a simple 10-minute DIY installation!
You might need an adjustable wrench to loosen and tighten the cold water outlet connection.
The filter housing itself can easily be installed by hand using the included wrench.

Customers praised this stainless steel filter for "easy installation" and significantly improved water taste. Many noted better-tasting coffee and pasta. The sturdy build quality and compact design were highlights. Some customers reported reduced water pressure and minimal filtration difference, with one noting difficulty replacing cartridges.
I absolutely love my new PJURE Filter! I’ve been looking for so long for an easy solution that doesn’t take up space on the countertop or require filter changes every month. This one is perfect! It was super easy to install, and since we’re renting, it’s a huge plus that we can easily bring it with us when we move. We could taste the difference immediately. I will recommend this to all my friends!
Super easy to install and the difference was immediate. The filtered water tastes amazing!
I very happy about the water and the installation was super easy
Cumple perfectamente con todo lo que ofrecen!!!
Excellent filter, easy to install!
Beside getting rid of all the nasties in the water, I was pleasantly surprised by how much difference the filter made to the taste of our water, it is amazing! Coffee tastes better- we can even taste the difference in how the pasta taste.
I’ve been using the PJURE Stainless Steel Water Filter for a few weeks and it noticeably reduces the chemical smell and taste of tap water, making it cleaner and more pleasant to drink. The water pressure is reduced but still acceptable—no major issues for everyday use. The build quality is very nice: the stainless‑steel housing feels sturdy and premium, and installation was straightforward.
My TDS meter showed no change, so don’t expect the mineral composition of the water to be altered; this is more about taste and odor than removing minerals. Also, no lab test was done, so I can’t verify any claims about heavy‑metal or microplastic removal—only the taste, smell, and feel at the tap.
Easy setup, compact storage, good water.
Perfect.
Thank you, Greg!

My only recommendation - make the installation manual and video really idiot proof. I'm a technical dummy and made a few mistakes while installing the filter like not noticing that there is a difference between the inlet and outlet hose. Better marking would help avoid that moment of panic...
Thank you for taking your time writing such a detailed review, Andrea. We are stoked you are happy with the product! Thanks for choosing PJURE and we will look at the improvements you suggest! I can assure you we are working with better content as we speak. Thanks again - Lars
Quality of steel is good but comes to water I didn’t feel much difference after few iterations felt as same as before.
Thank you for your review!
If the chlorine levels are already low in your tap water, the taste difference might be more subtle.
But there are a lot of other nasties you are no avoiding - so you can be assured the water in your tap is cleaner than before. Let me know if you have any questions and we are here to help!
Não consegui desapertar o filtro com a chave para substituir o cartucho do filtro no futuro. É preciso fazer muita força?
Obrigado pelo seu comentário 😊
Na primeira vez, o filtro pode estar bastante apertado — isso é normal, pois vem bem fechado de fábrica para garantir a vedação durante o transporte. Não tenha receio de aplicar um pouco mais de força para desapertar.
Quando voltar a fechar após a substituição do cartucho, não é necessário apertar tanto — apenas até ficar bem selado.
Caso precise de ajuda ou queira alguma orientação durante a troca, estamos sempre disponíveis para ajudar.
Tudo com anunciado, excelente!
Well-built, complete kit, easy to install even for first-timers
Excellant
Its quite early to say. But the water tastes good with nothing unusual;)
It is a great water filter, easy installatiob and the water tastes amazing!
There is just one Thing not so clean from the manual. Where do the lock clips, shown in the fig. Components included, have to placed?
Once again thanks for the good Support and the Fast delivery!
Easy mounting and great quality product.
I did so much research before I randomly stumbled over this, and I am so glad I did as I was close to buying a (very ugly) and expensive reverse osmosis system, to later learn it takes away all the minerals. This not only makes the water taste great, but with all the documentation they provide I feel very safe! And it was easy to install for real, even for me (and im not handy at all haha)
After 7 years of living in Lisbon where water quality is below average, it’s safe to say this filter has finally changed that! We can now give our baby water from the tap and what a relief it is to be able to skip the water bottles.
Easy to install, delicious water taste and the customer service we received was outstanding!
High-quality stainless steel filter that really makes difference.
Impressed with the quality and performance. Totally worth it!
Great quality filter — works perfectly!
