Water Filtration FAQ

Why Do I Need A Water Filter For My Coffee Machine? 

Many are not aware of the importance of water filtration to prevent breakdowns and optimise coffee taste. The heating and cooling process in each coffee machine attracts scale from the water, and this tends to accumulate in the boiler, on pipes, in the group head and on internal components. This, if not removed, leads to blockages and leakages. and eventually can lead to a technician's 'death sentence' when scale is evident everywhere and isn't worth while removing.

How to avoid that?

There are 3 things you need to know about water quality:

  • Sediment reduction - removing small particles like rust, dirt, sand and micro organism is essential to protect internals, especially the boiler that can develop a 'sludge' and attract scale development
  • Chemical reduction - especially chlorine, which greatly affects the taste
  • Total hardness (TH reduction) refers to magnesium and calcium. These can affect water temperature, pressure, steam performance and taste. Using good water filtration means avoiding deterioration and reducing service cost throughout the life of the machine

Most filters achieve the reduction of the first 2 but a softening agents that effectively reduce down to 90% scale in the water are not common, but is mostly needed to protect your machine.   

How To Choose A Filter For My Home Coffee Machine?

You already have a built in filter in your fridge or under the sink and you want to keep it?

Add the IN1218-2K filter inline after your existing system (and before your tap) to reduce TH. It reduces up to 90% scale while keeping the right PH level for Espresso

You do not plan to plumb- in your machine nor the water filtration system?

An effective bench top filter is our Aqua Pro for $112.50 (or $95 if purchased with a machine). It sits next to your sink and connects easily to the end of most kitchen taps. You can choose between filter water and tap water easily. This filter offers a combination sediment, chemical and softening capacity. 

You want to plumb-in your machine and also keep a dedicated tap for softened water?

We recommend the Brita C150 Kit. You only need 1/2 inch male tap and you can connect this kit yourself. It comes with filter, hose, counter top tap and 350kpa restricted valve. The filter is a 3 stage Brita filter for effective sediment, chemical and TH reduction. 

It is also available without the tap, please ask.

Please note the filters above are recommended for a home environment with TH of max 160ppm and under 300ppm TDS (total dissolvable solids). Any reading higher than that, please contact us to discuss a different filter.

Water Filtratrion FAQ

1. How do I find my water's TH and TDS?

To know your TH & TDS you can search online in your local water authority web site or call them. You can also get TH stripes here or arrange with us for your water sample to be sent out for testing.

2. My water isn't that hard, do I still need a filter to soften the water?

As its the frequent cooling and heating process that attracts scale, domestic machines are more prone to scale, even if used with soft water. Hence why a good combination softening system can keep scale level to minimum

3. We use rainwater, do I still need a filter?

Rainwater are indeed soft, but if unfiltered for sediments (dust, soil) and micro organism, it can be harmful to your coffee machines. Most rainwater systems do come with a mechanical filter at point of entry which should solve this issue, check you have one. Another well known occurrence with rainwater is the occasional lack of sensor signal to indicate low water level in the tank as the water low in electrolytes that are present in normal tap water. Mixing normal tap water with your rainwater can improve conductivity.
