Based on Coolbinia's water profile
Reverse Osmosis (RO) System Top pick
Your water hardness is 204 mg/L (very hard). An RO system removes 90–99% of dissolved minerals, effectively eliminating limescale and improving taste.
Salt-Free Scale Reducer
At 204 mg/L, a whole-house salt-free conditioner or electronic descaler can reduce limescale buildup on pipes and appliances — it limits scale, but doesn't remove hardness minerals from the water.
Gravity Water Filter
A gravity filter is a versatile, budget-friendly option that requires no plumbing. Good for general filtration of chlorine, sediment, and common contaminants.
Activated Carbon Filter
A carbon filter removes chlorine taste and odour, the most common water quality complaints. An affordable option for everyday drinking water improvement.

This level causes significant limescale buildup in kettles, hot water systems, and pipes. Fluoride is 0.84 mg/L, within normal range. Total dissolved solids (TDS) are 576 mg/L — moderate levels.

Utility reports average the grid — not your home
Coolbinia's water meets ADWG standards at the source, but old pipes, roof tanks, and ageing plumbing can add lead, copper or bacteria before the water reaches your tap. These won't show up in your utility report.
Check your own tap before buying a filter or assuming the suburb average matches your home.
