Why is drinking filtered water important?
Buy a water filter!
Why? I hear you asking.
Tap water quality is sub standard and riddled with unwanted chemicals, bacteria, pathogens & heavy metals.
Fluoride especially messes with your thyroid and thats not something that anyone wants.So, its is a worth while investment to purchase a good quality water filter. It's way cheaper than buying bottled water too.
The top of the range would be a reverse osmosis filter with a good quality model setting you back around $650 AUD. An entry level water filter will be enough to get your started. RRP is around $150AUD and it will filter out all the unwanted extras except fluoride.
