Our cartridges are designed for easy DIY replacement and you can change them yourself with our simple 4 minute instruction video.
The system has 5 filters in total. All filters except the RO Membrane need renewing once a year. These 4 filters are the ones that make up our Standard Service Kit.
The RO Membrane has a longer lifespan and is only replaced once every three years.
These time frames can vary depending on your water quality and usage, and if you live in a hard water area you may need to replace them sooner.
We also send you a reminder when your cartridges are due.
The installation process is simple and flexible to suit your needs:
- Use any licensed plumber: Contact your go-to plumber, or reach out to us and we can help connect you with an independent licensed plumber.
- Prefer to do it yourself? The system includes a clear installation manual, and we offer phone support to guide you through it.
Note: To comply with state plumbing codes, it is recommended to use a plumber.

PH+ ALKALINE MINERALISER
THE MINERALISING ELEMENTS
-
Magnesium
This naturally alkaline mineral is crucial for over 300 biochemical reactions in the body. It aids in the activation of nerves and muscles, contributes to the proper development of bones, and is crucial for DNA synthesis and energy metabolism.
-
Calcium
Vital for maintaining strong bones and teeth, calcium is a key player in your body's overall health. It also plays an essential role in blood clotting, muscle function, and nerve signal transmission.
-
Far-Infrared Ceramic Beads
Far infrared energy is extensively used in the Far East because of its therapeutic properties. The far infrared ceramic media emits far infrared rays (FIR) which reduce the clusters in the water molecules – increasing the bio-available response and oxygen absorption in the body.
-
100% Coconut Carbon
Enjoy the purity of water filtered through 100% coconut carbon, which excels at removing impurities and odors. This eco-friendly material ensures your water tastes fresh and clean with every sip.




FAQs
Our Alkaline+ Purifier uses reverse osmosis filtration, which means it removes up to 99.9% of all contaminants including:
- Sediments like dirt, dust & rust
- Chlorine, Chloramines & THMs
- Fluoride
- Heavy metals including copper, lead, aluminium, arsenic, cadmium & mercury
- Pesticides & herbicides

Reverse osmosis Filtration: Using the most comprehensive filtration technology in the industry our Alkaline+ Purifier removes up to 99.9% of all Total Dissolved Solids (Contaminants).
Remineralisation: Remineralisation is an essential feature when looking for a water filter. Once the water has been through the super fine reverse osmosis filtration, it requires replenishment of minerals. Our Alkaline+ Purifier uses a Mineralising Cartridge made up of 100% natural and raw minerals including magnesium, calcium and many other trace minerals to mineralise and organically raise the ph of the water.
Far-infrared Ceramic Beads: Our Alkaline Mineralising Cartridge even goes a step further to include Far-infrared ceramic beads. These beads emit far infrared rays (FIR) which reduce the clusters in the water molecules – increasing the bio-available response and oxygen absorption in the body. Far-infrared energy is extensively used in the Far East due to its therapeutic properties.
Slim Design & Easy Maintenance: The Alkaline+ Purifier's slim design takes up less than half the space of traditional reverse osmosis systems. It's easy quick-change disposable cartridges means there is no chance for bacteria build up and changing your cartridges is a breeze!
Yes, absolutely! In fact, of all the filtration methods, reverse osmosis is the only method that effectively removes fluoride from your tap water. This is due to the filter's very small membrane size of 0.0001um providing a strong barrier against fluoride.
With the Alkaline+ Purifier, there is no need to boil water for baby formula! This is because our reverse osmosis system removes far more contaminants than boiling does.
Our cartridges are designed for easy, DIY replacement so you can do it yourself with our easy 4-minute instruction video included with your Service Kit.
Four of the cartridges (Sediment Filter, 2x Carbon Filters & PH+ Alkaline Mineraliser) require renewing annually and the RO Membrane cartridge requires renewing once every 3 years but these time frames can vary depending on your water usage and quality.
If your city has hard water, your cartridges may require renewing more frequently. We send you a free reminder when your cartridges are due for replacement.
Our system is designed for straightforward installation under your sink with clear instructions provided. Some customers find they can install the Alkaline+ Purifier themselves and we're here to provide support.
To comply with state plumbing codes, it is recommended to use a plumber.
We can help connect you with an independent licensed plumber for installation or contact your go-to plumber for installation.
Our system replicates nature's way of mineralising water. In nature, water flows over rocks absorbing alkaline minerals and raising the pH. Similarly, after the reverse osmosis filtration removes all contaminants and minerals, the water flows through our PH+ Alkaline Mineralising Cartridge which contains raw, natural minerals, including, magnesium, calcium and other trace minerals. These naturally alkaline minerals are absorbed into the water which organically raises the pH to a high alkaline level.
Yes, you can still install the Alkaline+ Purifier even if you're renting! It is designed for easy installation, ensuring that the integrity and functionality of the existing plumbing are not compromised. Plus, it's easily removable for when you relocate.
Pair it with a 3-way tap that replaces your existing kitchen tap, offering hot & cold tap water, and filtered alkaline water from a single faucet. This renter-friendly solution eliminates the need to drill an extra hole for a filter faucet.
Need help chatting to your landlord about it? Send us an email at info@kapha.com.au with your name, rental address and a photo of under your sink and we'll provide you with a custom Request Letter that you can send to your agent/landlord for approval.
