Do you purify your water?

Why did I choose to get a water filter for our family?
I chose to get a water filter for our home about 7 years ago primarily so that I knew the water we were consuming and using was SAFE. 

There were also other contributing factors such as our daughter's eczema, my husband and our daughter's asthma, our gut health (microbiome) and taste.

Up until that point, as I had with cleaning products and food, I assumed that the industry and government regulations would be ensuring that our water quality was safe, I discovered their version of safe and mine were very different.

Your tap water will likely have chlorine, sediment, bugs, fluoride, and rust.  It can also contain heavy metals, pesticides and chemical stabilisers all of which can increase your chemical load and affect your health.  The standard of what levels are safe is controversial and before it gets to your home you have no control over any of it.

Let's talk about Chlorine:  There are pros and cons with using chlorine for water disinfection, currently, the data says that the pros outweigh the cons. 

The pros are that it kills dangerous bacteria such as salmonella and E. coli, and many viruses which prevent you from getting very sick and even dying. 

The cons are that it also binds to organic matter in the water and makes trihalomethanes (THMs) which are known carcinogens.  According to the U.S. Council of Environmental Quality "cancer risk among people drinking chlorinated water is 93% higher than among those whose water does not contain chlorine."

Studies in animals, and also correlation data in human populations have shown there are definite links between chlorination and increased cardiovascular disorders and heart disease. 

Chlorine also kills good bacteria, which greatly affects the diversity and health of your good bugs in your body (microbiome – more on that another day), which affects your immune system and the supply of many of your bodies nutritional requirements.

Even in small doses, chlorine is known to dry out skin, cause allergic reactions and cause respiratory symptoms (i.e. asthma).   The inhalation and absorption of chlorine via showering and steam are thought to contribute up to 2/3 of your total exposure.

Chlorine is a pesticide, and the current scientific position on it is that "the dose makes the poison".  Let alone all the known heavy metals, chemical contaminants and other intentionally added substances such fluoride (more on that another day too).  For me, and my family, we'd rather not drink or cover our bodies in anything that could be considered a poison. 

So how do you decide which filter to get? 
I spent hours trawling the internet and then I spoke to a couple of experts to decide what sort of filter I needed.   
Your source of water and your budget will affect which filter you choose. 

In an ideal world, you would install a whole house filter to remove the chlorine, metals and sediment etc.  As well as a bench or under bench filter to remove the fluoride, plus any heavy metals and contaminants from your own water pipes.  If you are unable to get a whole house filter, then at a minimum install one for your drinking water and installing a shower head filter will also make a big difference.

The basic guidelines are

Good choice:  Kitchen Filter (bench or under bench) and a showerhead filter

Better choice:  Whole house filter

Best choice:  Whole house filter and Kitchen filter (bench or under bench) 

We chose to get the whole house filter as we couldn't afford both at the time, we have since moved and are on tank supply, so we use our whole house filter with UV treatment and different cartridges to filter out sediment, heavy metals and e.coli etc and as it is rain collection there is no added chlorine, fluoride and other such things.

I researched the different companies and their pricing and found that NZ Filter Warehouse was offering the same products (some were actually better) at much better prices.  After a phone consultation with Peter, I was confident I had chosen the right filter for the job and had it installed.

What were the results?
The difference in taste was immediately obvious, also I was surprised how different the water felt and smelt in the shower – it felt "soft".  Our daughter's skin wasn't as dry and her eczema decreased.  Most importantly I had the confidence that we were no longer exposing our bodies to unnecessary chemicals that could be harmful to us.  I had made our water at home SAFE.

If you would like to do the same, visit  to check out their whole house, under bench and bench top filters, they have the best quality filters at wholesale prices.
