Our Technology

How Our Jug Filters Work

Our filtering jug cartridges take a three-step approach to filtering impurities and hardness from your water:

  1. As the water pours into the cartridge, it first encounters a filtering material that removes suspended particles including sand and rust.

  2. Next the water encounters our ion-exchange resin along with high-quality activated charcoal with silver. This part of the cartridge greatly reduces chlorine, dissolved iron, hardness, organic compounds, and improves the taste, clarity, and odour.

  3. And the third level contains our unique patented "Catalon" filtering material that further reduces heavy metals, along with bacteria and viruses (this is particularly rare among water filtering jugs).
Typical cartridge life span: 350 litres
Typical filtering speed: Up to 0.5 litres per minute
Supports water up to: 40°C


Typical Removal Effectiveness During Life of Cartridge




How the Typhoon Cartridge Works

The water filtering process uses three technologies to remove impurities and hardness from your water:

Step 1 - Mechanical Cleaning

What this means is suspended particles are removed from the water.  Depending how clean or not, how old or new, the pipes coming into your home are, is what impacts what ends up in your water.

Perhaps on the journey into your home, the water travels down a rusty pipe.  Could some of that rust make its way into your water?

Now, however high quality the water infrastructure in your area, it's difficult to know exactly what sort of plumbing the water is travelling through.

However let's be clear - we're certainly not trying to scare you!  We don't believe in scaremongering.  But it is a fact of life that some pipes get old, and so impurities sometimes sneak into water.

So that's why we're proud to offer the Typhoon.  In fact, we believe it should be part of every single home, since we feel strongly that truly clean and healthy water is everyone's right.  The Typhoon system will work for you automatically helping to keep the water in your home healthy and fresh, and will solve a lot of the problems you may be experiencing regarding limescale.

So this mechanical cleaning part of the process removes such solid impurities as rust, even down to five microns (more accurately referred to as micrometers).  5 μm if we're going to get technical!

And if you consider a typical hair is 50 microns, this part of the filtering process removes solid impurities from the water many times smaller than the width of a human hair.  And that's just step one!...

Step Two - Ion-Exchange Cleaning

Now, "ion exchange" is certainly a rather technical term.  And we're confident the vast majority of customers (and future customers) that visit this site aren't scientists.  So rather than bamboozle you with scientific-sounding words that serve no purpose but make us sound clever, let's keep it simple...

This part of the process uses our powerful "Aragon 3" filtering material.  This material is specially formulated and works to allow water to pass through it, but captures the vast majority of impurities during that process.

Perhaps think of it as an incredibly complicated maze.  The water just passes right through, but the chlorine, the iron, the heavy metals, bacteria and viruses... they all reach dead ends, and get stuck in the maze for good.  So clean, healthy water gets past this step, what isn't clean and healthy water, doesn't.

Plus, through extensive testing we discovered this part of the filtering process removed the vast majority of hardness from the water.  In fact, what this approach does is turn "bad calcium" that produces limescale build up, into "good calcium" called Aragonite (hence the Aragon 3 name).

Aragonite is easily absorbed into the body, and doesn't create limescale buildup in pipes and appliances.  So you get the benefits of calcium in your water, without the typical many (and often expensive) drawbacks of hard water.

Step Three - Sorption Cleaning

Yes, we know this is another phrase that isn't particularly helpful or easy to understand.  But in a nutshell - this part of the filtering process uses a combination of activated charcoal along with silver to further remove impurities and hardness from the water that flows through your filter.

And it's true, that many water filters offered by our competitors use activated charcoal too.  There's a reason for that - it works!  In fact, charcoal has been used for filtering impurities for many centuries.

Of course, this part of the filtering process is just one of three.  Taken altogether, these three technologies dramatically improve the quality of your water.  And our patented, exclusive, powerful filtering material Aragon 3 (step two of this process - detailed above) is unique to our filters, and we believe cleans your water more effectively than the majority (if not all) competitor solutions on the market - while - also filtering quickly.

Since we've been developing water filtration technologies since 1986, and since we now have millions of happy customers worldwide, cleaning water quickly and effectively is something we're very good at - even - if we do say so ourselves!


What's Removed From Your Water (And What Stays In)

So what does our three-step approach remove from your tap water?  Well:

Particles measuring ˃ 0.1 μm 100 %

Heavy and radioactive metals
(lead, cadmium, copper, strontium-90, cesium)

Up to 95%


Up to 100%


Up to 92%


Up to 95%


Up to 97%

Petroleum products

Up to 90%

Bacteria and viruses

Up to 100%


And remember:

  • Much, if not all of the hardness is removed from the water.

  • Plus, unlike some filtering systems that remove too much (the good along with the bad), we ensure beneficial minerals are part of your water.  This gives your water a better taste, and helps keep it healthy.


Filtering Effectiveness Over Time

Contaminant Start of Cartridge Life Middle of Cartridge Life End of Cartridge Life
Insoluble particles - rust, sand, silt particles coarser than 1 μm 100% 100% 100%
Iron 99% 99% 97%
Heavy and radioactive metals 100% 100% 98%
Available chlorine 100% 100% 99%
Organic compounds, carcinogens, pesticides 99% 99% 97%
Hepatitis A virus and Escherichia coli 100% 100% 100%



Independently Tested

Perhaps you're asking yourself:

  • "Will this filter really clean my water?"

  • "Is it better than what the competitors offer?"

  • Or perhaps more specifically, "Is this product actually any good?" :)

Well, we certainly understand your concerns, and we don't want you to just take our word without any proof!...

Millions of Customers Worldwide

Our filtering technology is now used by over 20 million customers worldwide, with most of these customers in Asia and Europe, although we're now also distributing our products to the English-speaking world...

We estimate that well over 100 million litres of water every single day is filtered using our products.

Plus, the technologies we've developed have been independently confirmed by more than 20 patents and have been recognized by leading scientific organisations including:

NSF International

Our products match or exceed the requirements set down by NSF, the public health and safety organisation.

The Wellthy Corporation (part of Mitsubishi Chemical)

Since our products are sold in Japan, the technology has been tested to verify they match Japan's strict water purification requirements.

Institut Pasteur

In 2014 the French-based Institut Pasteur, a non-profit foundation founded in 1888 by the famous chemist Louis Pasteur, independently confirmed Geyser filters removed the following to 99.9999%: poliovirus, rotavirus, legionella and salmonella.
