Waters Co vs Earth’s Water: Which Australian Benchtop Filter Is Actually Better? (2026)
2026 — Tested & Compared
Waters Co wins on fluoride removal and warranty. Earth’s Water wins on capacity and entry price. Neither is a clear knockout — your household size decides it.
Both are genuine Australian gravity filters that remove fluoride, chlorine, and heavy metals without electricity or plumbing. The difference comes down to three things: Waters Co’s 99% fluoride removal rate and lifetime warranty vs Earth’s Water’s larger 9L reservoir and lower subscription entry price. If fluoride is your primary concern, Waters Co. If you run a large household and want the lowest upfront cost, Earth’s Water.

Waters Co BIO 500 MAX 7L — Full Review
✓ Pros
- 99% fluoride removal — patented nano carbon compound, independently tested
- Lifetime warranty — only gravity filter brand in Australia offering this
- 99%+ forever chemicals — independent lab result published by brand
- 13 stages of filtration — sterilising, filtering, and mineralising in one pass
- 6,000L filter life — 18 months between replacements for most households
- One-time price — no subscription lock-in, transparent cost
- 60+ trace minerals — alkaline pH 7.6–8.5 with bio-organic mineral profile
✗ Cons
- $649 upfront — higher entry cost than EW’s subscription starting price
- 7L vs 9L — smaller reservoir loses to Earth’s Water for large households
- Filtration speed — gravity-fed, not instant — takes time to fill
- Glass reservoir — breakable if dropped, not ideal for homes with children
What the 13 Stages Actually Do
Waters Co’s multi-stage approach covers more than most gravity filters. The first stages handle coarse sediment and rust (common in older Australian plumbing). The middle stages target chlorine, chemicals, and heavy metals via ceramic and carbon filtration. The critical stage for most Australian buyers is the patented nano carbon compound specifically designed for fluoride reduction — Waters Co claims up to 99% removal, with independent testing confirming the figure. The final stages add back alkaline minerals and far-infrared ceramic activation, producing water with a pH between 7.6 and 8.5.
For comparison, most standard Brita-style pitchers use 1–2 filtration stages and do not address fluoride at all. The BIO 500 MAX is a fundamentally different product category.
Fluoride Removal — Why the 1% Gap Between WC and EW Matters
Both brands claim high fluoride removal rates (Waters Co 99%, Earth’s Water 98%). In practice, 1% is unlikely to be meaningful at the tap-water concentrations found in Australian cities (typically 0.6–1.0mg/L). The more important distinction is that Waters Co publishes independent third-party test results to support their fluoride claim. Verify what testing methodology supports the figure before treating either claim as absolute — independently verified numbers are always more reliable than brand-stated specifications.
Earth’s Water 9L Glass Natural Bamboo — Full Review
✓ Pros
- 9L reservoir — 29% more capacity than Waters Co, better for families of 4+
- Lower entry price — $431 subscription vs $649 one-time
- Borosilicate glass + bamboo — high-end aesthetic, LFGB certified materials
- Free shipping — no minimum order threshold
- BPA-free construction — 100% confirmed across all components
- 98% contaminant removal — covers chlorine, heavy metals, and fluoride
✗ Cons
- Subscription-only pricing — no simple one-time purchase option visible on site
- Less filtration transparency — COREtech™ stages not individually disclosed
- No lifetime warranty — warranty terms not prominently stated vs WC
- Glass is breakable — same risk as Waters Co’s blue glass reservoir
- pH range not published — no documented alkaline output range
The Subscription Model — Cheaper Entry, Higher Long-Term Cost?
Earth’s Water sells the 9L Glass Benchtop via subscription: $431 for a 3-month plan (includes the unit + one filter), $456 for 6 months, or $499 for 12 months. The compare-at price — what you’d pay at full RRP without a plan — is approximately $575 for the unit alone.
This structure means the entry price is lower than Waters Co, but ongoing filter replacement costs need to be factored in separately. For Waters Co, filter replacements are purchased independently (budget approximately $60–90/yr at a 6,000L filter life). For Earth’s Water, filters are bundled into the subscription, so you’re essentially prepaying for future replacements.
Capacity — Why the 9L Matters for Families
The 2L difference between 7L (Waters Co) and 9L (Earth’s Water) matters most for households of 4+ people. A family drinking the recommended 2L/person/day will drain a 7L reservoir in under a day. A 9L reservoir buys an extra 12–18 hours between refills. For couples or singles, the 7L Waters Co is more than sufficient.
Head-to-Head: The Definitive Comparison
Buy Waters Co BIO 500 MAX if…
- Fluoride removal is your primary concern
- You want a lifetime warranty and no subscription
- You’re a couple or live alone (7L is plenty)
- You want transparent, independently tested specs
- Long-term cost matters (cheaper over 2+ years)
Buy Earth’s Water 9L if…
- You have a larger household (4+ people, need 9L)
- Lower upfront entry price is the priority
- You prefer the bamboo + borosilicate glass aesthetic
- Free shipping on every order matters
- You prefer filters bundled into the plan
The Bottom Line
Waters Co is the better choice for most Australian buyers who care about filtration quality and long-term value. The combination of 99% fluoride removal backed by independent testing, a lifetime warranty, and a lower total cost of ownership over 2+ years makes it the more defensible purchase. The 7L reservoir is sufficient for households up to 3 people.
Earth’s Water makes a compelling case for larger families. The 9L borosilicate glass design is genuinely premium, the subscription entry price is lower, and the aesthetics rival anything else in the gravity filter category. If you have 4+ people in the household and need the extra capacity, or if the $431 entry point fits your budget better than $649, Earth’s Water is the right choice.
Both brands are legitimate, both ship promptly across Australia, and both deliver meaningfully cleaner water than unfiltered tap. The difference is in the margins: warranty depth, filtration transparency, and daily capacity. Waters Co edges ahead on the first two; Earth’s Water wins on the third.
Frequently Asked Questions
Is Waters Co or Earth’s Water better for fluoride removal?
Waters Co claims 99% fluoride removal vs Earth’s Water’s 98%. Both use specialised filter media targeting fluoride — Waters Co’s patented nano carbon compound is the specific mechanism they cite. In absolute terms, 1% difference is negligible at Australian tap water fluoride concentrations (0.6–1.0 mg/L). The more meaningful difference is that Waters Co publishes independent third-party test data. If fluoride removal is your primary concern, both perform well, but Waters Co provides more evidentiary support for their claim.
Which has a bigger water reservoir — Waters Co or Earth’s Water?
Earth’s Water 9L Glass Benchtop holds 9 litres vs Waters Co BIO 500 MAX’s 7 litres. For a household of 1–3 people, the 7L is typically sufficient. For families of 4+ drinking 2L/person/day, the 9L reduces refill frequency and is the more practical choice.
Do either of these filters remove PFAS or forever chemicals?
Waters Co specifically claims 99%+ removal of forever chemicals (PFAS) and references independent testing to support this. Earth’s Water claims contaminant removal but does not publish specific PFAS removal data on their product page. If PFAS/forever chemicals are a priority, Waters Co provides stronger documented evidence.
Does Waters Co or Earth’s Water require electricity or plumbing?
Neither requires electricity or plumbing. Both are gravity-fed benchtop filters — you fill the upper reservoir with tap water, gravity pulls it through the filter media, and filtered water collects in the lower reservoir. This makes both suitable for renters and apartments where under-sink installation isn’t an option.
What is the filter replacement cost for each brand?
Waters Co: filter sets are purchased separately (expect $60–90 AUD per set, with a 6,000L or 18-month rating, so roughly one replacement per year for most households). Earth’s Water: filter replacements are bundled into subscription plans. The 3-month subscription at $431 includes the unit and one filter; renewal plans vary by frequency. Waters Co’s standalone filter cost is typically lower per year if you buy the unit outright.
Which brand has a better warranty?
Waters Co offers a lifetime warranty on their benchtop filters — the only gravity filter brand in Australia to do so. Earth’s Water does not prominently state warranty terms on their product pages. This is a meaningful differentiator if long-term product reliability matters to you.
Is Earth’s Water available without a subscription?
Earth’s Water primarily structures the 9L Glass Benchtop as a subscription product (3-month, 6-month, or 12-month plans). The subscription pricing ranges from $431–$499 and includes the unit plus filter replacements on a set schedule. The compare-at price — the non-discounted RRP — is approximately $575 for the standalone unit. Check their website directly for the most current pricing options.
Which gravity filter is better for an Australian apartment?
Both work equally well for apartments since neither requires plumbing or electricity. The Waters Co BIO 500 MAX has a slightly smaller footprint due to the 7L capacity, which may suit smaller benchtops better. Earth’s Water’s 9L is taller and takes more counter space. For compact kitchens, Waters Co is the more space-efficient option.
