The best Waters Co water filters are the AceBio+ 1.0 Litre Jug (A$229) for small households wanting an easy countertop upgrade, the BIO 500 Bench Top Filter (A$729) for daily drinking water at the kitchen sink, and the BIO 1000 (available in Black or Grey, A$999) for larger families who want maximum fluoride reduction in a single tank. All three run on gravity-fed filtration technology the brand has developed since 1984, with independent lab testing behind every system. Below, the four models are compared by price, capacity, and who each one suits.
1
AceBio+ 1.0 Litre Alkaline Mineral Water Filter Jug
A$229A$259waterscoaustralia.com.auPros:
Makes tap water taste noticeably cleaner within the first fill
Cuts down on single-use plastic bottle waste at home
Fits easily in a standard fridge door shelf
Reduces fluoride, PFAS, and microplastics without any plumbing work
This jug runs 10 stages of sterilizing, filtration, and activation packed into a compact 1-litre reservoir. It targets fluoride, PFAS, parasites, and microplastics while adding minerals back into the water, a step most basic carbon jugs skip entirely. It suits renters, small apartments, or anyone testing filtered water for the first time before committing to a larger system. Reviewers on the brand's own site rate it 4.9 out of 5 across more than 680 reviews, with many noting the filter lasts close to two years. Those needing more than a litre at a time may find themselves refilling often during busy weeks.
Highlights:
- 10-stage filtration and mineralisation process
- 1.0 litre capacity, countertop or fridge-ready
- Filter cartridge rated for extended multi-month use
- Reduces residual chlorine, heavy metals, and bacteria
- Part of Waters Co's gravity-fed system lineage dating to 1984

BIO 500 5.25 Litre Bench Top Water Filter
A$729A$849waterscoaustralia.com.auPros:
Removes up to 99% of fluoride from everyday tap water
Balances water pH instead of just stripping contaminants
Covers daily drinking and cooking needs for small to medium households
Lowers plastic bottle reliance with a refillable benchtop tank
The black edition of the Bio 400 model, this benchtop unit uses activated charcoal and KDF media to manage both chlorine and heavy metal reduction while keeping the water's mineral balance intact. Its 5.25 litre capacity rated for roughly 12,000 litres or 48 months of use makes it a realistic fit for two to four people drinking and cooking with filtered water daily. One water-quality reviewer called it a system that "really does remove fluoride," pointing specifically to the 99% figure. It sits on the counter rather than under the sink, so kitchens with limited bench space should measure first.
Highlights:
- 5.25 litre glass reservoir, black edition of the Bio 400
- Activated Charcoal and KDF filtration media
- Rated lifespan up to 12,000 litres or 48 months
- Removes up to 99% of fluoride
- Gravity-fed, no plumbing or electricity required

BIO 1000 Black 10 Litre Bench Top Water Filter
A$999A$1,249waterscoaustralia.com.auPros:
Supplies filtered drinking water for larger households without refilling often
Strips fluoride and heavy metals down to trace levels
Adds back over 60 trace minerals for better-tasting water
Reduces reliance on bottled water deliveries at home
Fifteen stages of filtration run through this unit's 10-litre hand-blown glass reservoir, a jump up from the 5.25-litre Bio 500 for households that go through water faster. It is built for families of four or more, shared offices, or anyone replacing a bottled water delivery service outright. One reviewer described it as feeling "like the Rolls Royce of water filters," though the same review noted the tap outlet could be wider for faster pouring. Waters Co markets this as part of its newer benchtop range offering 99.9% fluoride reduction. The higher upfront cost and larger footprint mean it suits kitchens with more counter space to spare.
Highlights:
- 10 litre hand-blown glass reservoir
- 15 stages of filtration and mineral activation
- Removes up to 99.9% of fluoride and heavy metals
- Adds 60+ trace minerals back into filtered water
- Replacement filter set available separately for ongoing maintenance

BIO 1000 Grey 10 Litre Bench Top Water Filter
A$999A$1,249waterscoaustralia.com.auPros:
Matches the Black edition's fluoride and heavy metal reduction
Blends into lighter kitchen colour schemes
Handles high daily water use without frequent refilling
Cuts the ongoing cost of bottled water to roughly $0.45 a day
Identical in performance to its black counterpart, this version swaps the finish to grey glass for kitchens that lean toward lighter tones. It carries the same 15-stage filtration and 99.9% fluoride and heavy metal reduction, making the choice between the two editions purely aesthetic. Large households, shared living spaces, or small offices get the most value from its 10-litre capacity, which the brand estimates can bring filtered water costs down to around $0.45 per day compared to bottled alternatives. Feedback mirrors the Black edition closely, with a 4.9 out of 5 rating across more than 200 reviews. Buyers who prefer a smaller footprint should look at the Bio 500 instead.
Highlights:
- 10 litre reservoir in grey glass finish
- 15-stage filtration matching the Black edition
- Reduces fluoride and heavy metals by up to 99.9%
- Estimated running cost around $0.45 per day
- Lifetime warranty on filter systems, per brand policy
Final Thoughts
Choosing between these four comes down to household size and budget rather than filtration quality, since all four share the same gravity-fed, mineral-restoring approach Waters Co has refined since 1984. The AceBio+ suits anyone testing filtered water for the first time at under A$230, while the BIO 500 and BIO 1000 scale up for households that go through more water daily. Shoppers torn between Black and Grey BIO 1000 editions can decide on finish alone, since performance is identical. Starting with the AceBio+ or BIO 500 is a reasonable way to gauge the value before investing in the larger 10-litre system.
