How much will I actually save switching from bottled water to a filter in a Brisbane apartment?

Filter payback depends entirely on your current bottled water spend and filter cost. Use the calculator above to see your exact 5-year savings and payback timeline. Most households will break even within months, then save progressively as cartridge costs stay flat while bottled water spend compounds.

What's the TDS reduction I can expect from a 5-stage RO filter?

Jayce's meter-tested data (Palm Beach QLD): mains water 69 ppm TDS, post-EcoHero 5-stage RO 3 ppm—a 95.7% reduction. Results vary by local water source. Check your council's water quality report for your starting TDS, then compare to your filter's spec sheet.

Is bottled water in Australia actually cleaner than filtered tap water?

No. Both must meet ADWG (Australian Drinking Water Guidelines). RO filters exceed these limits—Jayce's test showed 3 ppm TDS versus ADWG's acceptable range. Bottled water costs more, requires transport, and carries plastic leaching risk for no quality gain.

How often do I need to replace filter cartridges and what does it cost?

Typical 5-stage RO: pre-filters need periodic replacement based on usage and local water quality; RO membrane lifespan depends on your water TDS and daily usage—check your filter's spec sheet for your model's replacement schedule. Compare annual cartridge costs to your current bottled water spend using the calculator.

Will a water filter remove fluoride if my council adds it?

RO filters remove fluoride effectively—check your filter's spec sheet or NSF certification for exact removal rate (ADWG guideline: 1.0 mg/L). Activated carbon alone won't work; you need RO or distillation. NSW, QLD, SA, and WA councils fluoridize—verify your region's level.

What's the environmental cost of a water filter vs. bottled water over time?

Bottled water generates significant plastic waste annually—filter cartridge waste is substantially lower by volume. Filter system uses minimal electricity. Cartridge recycling varies by council; check local FOGO or recycling guidelines for your area's disposal options.

Can I use a standard water filter on bore water or tank water in a regional property?

Depends on your water's TDS and contamination profile. Bore water often has higher TDS—test first with a TDS meter. RO handles most issues, but tank water with sediment needs pre-filtration. Get a water test from your local council or private lab before choosing a filter type.

Is it worth upgrading to a 6-stage or 7-stage RO filter instead of a 5-stage?

Five-stage RO is sufficient for most homes. Extra stages add remineralisation or UV (higher cost) without significant contaminant gain unless your water test shows specific contaminants. Jayce's test showed 3 ppm TDS from 5-stage. Upgrade only if lab results justify it or you want remineralised water for taste.

Cost per litre (bottled) ~$2.40

Filter costs based on April 2026 Australian retail pricing. Annual filter costs are estimates — actual costs vary by usage volume and water quality. Bottled water cost per litre assumes ~3.5L/day household consumption across all uses (drinking + cooking). Break-even calculations assume full replacement of bottled water purchasing.

Not sure which filter removes what?

Different technologies remove different contaminants. Reverse osmosis (RO) removes virtually everything including fluoride, PFAS and arsenic. Carbon block removes chlorine and chloramine but not fluoride. Gravity filters depend on the canister type.
