Based on Hynam's water profile
Reverse Osmosis (RO) System Top pick
Your water hardness is 355 mg/L (very hard). An RO system removes 90–99% of dissolved minerals, effectively eliminating limescale and improving taste. Additionally, your fluoride at 1.1 mg/L is elevated — RO also removes 85–95% of fluoride.
Salt-Free Scale Reducer
At 355 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.
Fluoride Filter (Jug or Under-Sink)
With fluoride at 1.1 mg/L, a certified ion-exchange jug or activated alumina filter targets fluoride specifically (up to 99%).
Activated Carbon Filter
Your chlorine level is 0.9 mg/L. A carbon filter effectively removes chlorine taste and odour, and is one of the most affordable options.
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.

Why this filter for Hynam?
Based on the latest water quality data for Hynam, we've analysed the key parameters that affect filter choice. Your water hardness is 355 mg/L — classified as "very hard." This level causes significant limescale buildup in kettles, hot water systems, and pipes. Fluoride is 1.1 mg/L, which is above the 1.0 mg/L threshold where some people prefer removal. Standard carbon filters don't remove fluoride — you need reverse osmosis or activated alumina. Chlorine is 0.9 mg/L. While safe, this can cause taste and odour issues. Carbon filtration is very effective at removing chlorine. That's why we recommend a reverse osmosis (ro) system as the best primary filter for Hynam.
Utility reports average the grid — not your home
Hynam'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.
