Growing up in Melbourne we were always told that we had the best drinking water in the world... 

While it's certainly good by global standards, it wasn't until five years ago when I was really sick, that I began to look closely at what's in our drinking water and whether filtering it is a luxury or a necessity.

As I didn't have a water filter, I was purchasing bottled water and questioned whether this was really necessary, so I switched back to tap water and over the next two days deteriorated very rapidly.

I felt really nauseous and switched back to bottled water to see if it would make a difference. I started feeling better straight away, and then looked closely at what is in the water that comes out of the taps in our homes. 

When you consider that water keeps us hydrated, carries nutrients into our cells, helps us eliminate toxins, regulates our body temperature, wakes us up when we are tired, gets rid of headaches; that the water we shower and bathe in gets absorbed into our bloods...
