Fresh Filtered Water on Tap

Different Ways to Filter Water

So you’ve heard filtered water is great for you and your family but there are a few terms and methods out there that can be a bit confusing when you’re looking for a healthy drinking water solution. Or thinking of buying a water filter. So let’s take a look at a few..

First up, What’s the difference between Water Purification and Water Filtration?

Water purification is a commonly misunderstood term.

It means to remove what is unwanted or unhealthy from the water, sometimes it’s referred to as disinfecting the water. It’s basically treating the water to remove bacteria and potential viruses and making it safe to drink. It’s the process used to produce tap water or potable water and it’s at this point where chemicals such as chlorine and fluoride are added.

The fluoride is great for your teeth but the chlorine? Although it does a great job in disinfecting the water, we don’t need to drink it!

Water purification is a term used a lot, especially in the United States but just to confuse you more…‘pure’ water is actually water with everything stripped out of it, even the good minerals like magnesium and calcium. And your body needs these to function properly.

What is Water Filtration?

Water filtration is a method used to remove and reduce impurities in the water.

A good water filter acts like a sieve to remove unwanted particles from the water but leaves all the important salts and minerals in. The filtration method is also sometimes called the adsorption method. And this is where a substance is used, typically carbon to make the contaminants in the water adhere to the pores within the carbon.

So a good water filter system takes out all the bad stuff like chlorine, dirt, dust, rust, and cysts such as Giardia and Cryptosporidium but keeps in all those important salts and minerals to keep us healthy.

So what are some of the most common water filtration methods?

Water Filter Jug

A water filter jug on a kitchen bench is water filtration in one of its simplest forms.

It’s a great start and it removes a lot of the bad stuff but it doesn’t filter out cysts like Giardia and Cryptosporidium.

And it’s small. So you are forever filling up that jug and probably only using it for drinking. What about washing your veggies or cooking with filtered water?


Or using filtered water to make your coffee and tea taste better? Even using it for the ice in your cocktails or expensive Scotch whisky? That one little jug will be working very hard and it isn’t long before you’re changing the filter again and again or worse still…forgetting to change the filter and you’re back to drinking plain old tap water again!

Reverse Osmosis Water Filter

At the other end of the scale there’s the reverse osmosis water filter. There’s a lot out there about reverse osmosis water at the moment. But what is reverse osmosis and do you actually need it?

In short, reverse osmosis is a water filtration technology that uses a semi-permeable membrane to remove ions, molecules and larger particles from drinking water. This is achieved by passing water at high pressure through a thin membrane. However, this is only one stage of a four-stage process. Where the water passes through a sediment filter first, then a carbon filter, then the reverse osmosis membrane and finally a filter to remove the odour and taste.

Sounds good in theory but in reality a reverse osmosis water filter takes out a lot of the good stuff too, like the healthy minerals and salts, and the fluoride that keeps your teeth strong. That’s because most mineral particles are larger than water particles, so it’s like drinking distilled water. Plus by removing all the minerals it actually leaves the water tasteless. Some people then re-mineralise the water to make it tastier and for the health benefits. Therefore making it a more complicated and time consuming method of water filtration.

A reverse osmosis filtration system wastes a lot of water too. Depending on the system you choose, you’ll need approximately 4 to 7 litres of water to produce 1 litre of drinking water!

This method isn’t great for the environment either as there’s also a lot of energy used in the process. The other downside is that these reverse osmosis systems can take up a lot of space and are expensive to buy and maintain. Four stages means four filters to change, which can be very costly.

However, this type of water filter process can be good in some circumstances. For example, people with specific health issues or on kidney dialysis. And in parts of Australia with high TDS levels. TDS are the dissolved minerals salts and metals found in the water, in these areas this system is used to help reduce these levels. But for most metropolitan areas of Australia and for most people, this lengthy and expensive process really isn’t necessary.

So What other types of Water Filters are there?

There are plenty of household water filter systems that have been around for a while. So other systems you may have heard of are – counter top units, on tap systems and under sink water filters. Under sink water filters have come a long way since the older style bowl filters which were often difficult to clean and fiddly to maintain.

What is an Inline Water Filter?

These days water filter systems are designed for maximum quality, economy and ease of use.

A popular choice is an inline water filter system. These are as simple as one cartridge that you can attach yourself. With an inline water filter system you have access to fresh, filtered water on tap. It’s attached under your kitchen sink and filters all the water coming through your original tap.

So there’s no need for a separate tap. The filter removes all the nasties but leaves in all the important minerals and salts so you can enjoy all the health benefits of filtered water. Plus it leaves in the fluoride to keep your teeth healthy.

Unlike reverse osmosis water filtration systems, an inline water filter is cost effective and easy to install – you don’t even need a plumber and the cartridge won’t need to be changed for 12 months. Then when it’s time to change it, it’s a simple five minute process – as easy as changing a light globe.

With filtered water on tap, there’s no more re-filling your water filter jug several times a day and you can use it for drinking, cooking, even filling your iron and best of all it tastes great!
