Need help choosing your water filter package?

Answer a few quick questions and we will point you to the closest package and install timeframe.

Step 1 of 5

Are you replacing the same system or doing a brand new install?

Choose the closest match so we can guide you to the right package pathway.

How will the system be mounted?

This helps us guide you to the closest package pathway.

Is exposed pipework available from the main inlet to the dwelling?

Exposed pipework usually means a simpler install pathway. Hidden pipework usually pushes the job into a broader package.

Does this install require power?

Powered systems usually require the Platinum pathway where available.

How quickly do you want it installed?

Choose the timeframe that best suits you.

STEP 1. - Select Preferred Installation Day Anyday (Our installation day/time choice within 20 business days) ASAP - Within 5 Business Days

STEP 2. - Select Installation Area Brisbane, Logan, Ipswich, Redlands (Mainland Only) Gold Coast, Scenic Rim, Moreton, Lockyer Valley

Where a customer has a stone benchtop, it cannot be drilled for the installation of a separate filter tap. Drilling into engineered or natural stone surfaces can release fine crystalline silica dust, which poses a significant health risk (silicosis) to installers and anyone nearby, and may also cause cracking or damage to the bench. In these cases, we can provide the option of a 3-way mixer tap that combines hot, cold, and filtered water in one unit, or, if preferred, the filter can be connected to the existing kitchen mixer to filter all cold water — however, this is not recommended as it will also filter dishwashing and cooking water, leading to faster filter clogging and more frequent replacements. A wider selection of suitable 3-way mixer taps can be viewed here: https://www.jrgasandwater.com.au/collections/3-way-kitchen-mixer-tap-hot-cold-filtered.

Conductivity	316 uS/cm	477 uS/cm	Optimal	< 400 uS/cm (Best for mineral balance)	✅

Parameter	Why It’s Unnecessary or Harmful	Ideal Target
Fluoride (F⁻)	Added for dental health, but prolonged fluoride exposure has been linked to lower IQ in areas with high fluoridation, as suggested by multiple studies (e.g., 2019 U.S. and Canadian research). Excessive fluoride may also contribute to thyroid dysfunction and bone weakening.	0 mg/L
Chloride (Cl⁻)	Often present due to chlorine disinfection or natural sources. High levels can cause a salty taste and corrosion in plumbing.	< 50 mg/L
Copper (Cu)	Comes from corroding pipes rather than natural water sources. High levels cause a metallic taste and potential health effects.	< 0.5 mg/L
Manganese (Mn)	Naturally occurring but contributes to staining, metallic taste, and potential neurological effects at high levels.	< 0.05 mg/L
Iron (Fe)	Can come from plumbing or groundwater. Causes staining, bad taste, and appliance buildup.	< 0.1 mg/L
Nitrate (NO₃⁻)	Usually from agricultural runoff. Long-term exposure is linked to potential health risks, including "blue baby syndrome" in infants.	< 1 mg/L
Sulphate (SO₄²⁻)	Naturally occurring but excessive amounts can have a laxative effect and cause water to taste bitter.	< 50 mg/L
Total Dissolved Solids (TDS)	Measures the overall mineral content. Too high can cause taste issues and appliance scaling.	50 - 150 mg/L
Turbidity (Cloudiness)	Should be as close to 0 as possible for clean, pure water.	< 0.5 NTU
Silica (SiO₂)	Naturally occurring, but excessive levels can lead to scale buildup on appliances.	< 10 mg/L

Parameter	Why It’s Okay	Ideal Range
pH	Best when neutral for taste and plumbing safety.	7.0 - 7.5
Alkalinity	Helps stabilize pH and prevent pipe corrosion.	60 - 80 mg/L
Hardness (Calcium & Magnesium)	Essential minerals for health, but excessive hardness causes scaling.	60 - 120 mg/L
Sodium (Na)	Naturally occurring but should be kept low for health and taste.	< 50 mg/L

Parameter	Recorded Reading	Safe Range	Ideal Range	Recommended?
pH	6.34	5.5 - 8.5	6.5 - 7.5 (Neutral for best taste & safety)	❌ (Slightly acidic)
Turbidity (Cloudiness)	0.02 NTU	0 - 5 NTU	< 0.5 NTU (Clear water)	✅
Total Dissolved Solids (TDS)	11.63 mg/L	0 - 600 mg/L	10 - 50 mg/L (Balanced minerals, no scaling)	✅
Total Hardness	8 mg/L	0 - 200 mg/L	< 50 mg/L (Soft water, prevents scaling)	✅
Iron (Fe)	0.03 mg/L	0 - 0.3 mg/L	< 0.1 mg/L (No staining or metallic taste)	✅
Manganese (Mn)	0.009 mg/L	0 - 0.5 mg/L	< 0.05 mg/L (Prevents staining & neurological effects)	✅
Sodium (Na)	1 mg/L	0 - 180 mg/L	< 10 mg/L (Avoids salty taste)	✅
Chloride (Cl⁻)	1 mg/L	0 - 250 mg/L	< 10 mg/L (Prevents corrosion)	✅
Sulphate (SO₄²⁻)	0 mg/L	0 - 250 mg/L	< 10 mg/L (Avoids taste & digestive issues)	✅
Alkalinity	13 mg/L	Moderate	20 - 50 mg/L (Balanced pH stability)	❌ (A bit low)
Nitrate (NO₃⁻)	0.72 mg/L	0 - 11.3 mg/L	< 1 mg/L (Prevents health risks)	✅
Copper (Cu)	2.24 mg/L	0 - 2 mg/L (Exceeds limit)	< 0.5 mg/L (Prevents metallic taste & toxicity)	❌ (Too high, likely from pipes)
Silica (SiO₂)	0.1 mg/L	0 - 80 mg/L	< 10 mg/L (Avoids deposits on fixtures)	✅
Fluoride (F⁻)	0.59 mg/L	0 - 1.5 mg/L	0 mg/L (Not needed; linked to lower IQ & thyroid issues)	❌ (Should be removed)
Conductivity	18.17 uS/cm	Optimal	10 - 100 uS/cm (Indicates low impurities)	✅

Contaminant	Why It’s Unnecessary or Harmful?	Ideal Level
Fluoride (F⁻)	Not naturally present in rainwater. Studies (Harvard, U.S. EPA) link prolonged fluoride exposure to lower IQ, thyroid dysfunction, and skeletal issues.	0 mg/L
Copper (Cu)	Exceeds safe limit. Likely from corroding pipes or roofing. High levels can cause metallic taste and health risks.	< 0.5 mg/L
pH (Acidic Water)	Slightly too low. Acidic water can cause pipe corrosion and leach metals like copper into the water.	6.5 - 7.5
Alkalinity	Low alkalinity can make water unstable and prone to pH fluctuations.	20 - 50 mg/L
