Top 8 Benchtop Water Purifiers Reviewed
1
watersco
bio 1000 black 10 litre
15-stage filtration • Hand-blown glass • 99.9% fluoride removal • Up to 4-year filter life
value for money score
4.9/5
our top pick: bio 1000 black 10 litre
The WatersCo BIO 1000 is the culmination of over 40 years of research into water filtration by some of the world's leading scientists. Waters Co was first to market with natural gravity-fed systems creating alkaline mineral water back in 1984 and has continued to lead the market in research and development, setting the benchmark for all other brands to follow.
Featuring an unmatched 15 stages of sterilising, filtration and activation, the BIO 1000 functions as a premium benchtop water dispenser, turning ordinary tap water into great-tasting, alkalised, energised mineral water — no bottles or plumbing required. The hand-blown silica glass reservoir means no plastic ever contacts your filtered water — a critical consideration given growing concerns about microplastics.
What sets it apart: The patented nano carbon compound achieves 99.9% fluoride removal and 99% forever chemicals (PFAS/PFOA) elimination — the highest verified rates we tested. With filter life up to 12,000 litres (approximately 4 years for average households), it delivers the lowest cost per litre of any premium filter at roughly 3 cents.

watersco
bio 500 5.25 litre
13-stage filtration • Hand-blown glass • Compact design • 99.9% fluoride removal
value for money score
4.9/5
bio 500 5.25 litre
The BIO 500 is the compact version of the BIO 1000, offering the same world-class filtration technology in a smaller 5.25-litre form factor. It's ideal for couples, singles, or households with limited bench space who still want premium water quality.
Featuring 13 stages of sterilising, filtration and activation, it delivers identical 99.9% fluoride removal and 99% forever chemicals elimination. The hand-blown glass reservoir maintains the same zero-plastic-contact philosophy, and the filter set lasts up to 12,000 litres (approximately 3 years for smaller households).
Best for: Smaller households, apartments, or anyone wanting the same premium filtration in a space-saving design.
Pros
Same 99.9% fluoride removal as BIO 1000
Up to 3-year filter lifespan (12,000 litres)
Hand-blown glass reservoir — no plastic contact
13-stage filtration with alkalisation
Lifetime warranty on structure and parts

zazen
zazen alkaline water system 12l
Multi-stage system • Alkalising • Glass bottom + plastic top
value for money score
3.9/5
zazen alkaline water system 12l
The Zazen water filter is a popular Australian brand offering a comprehensive multi-stage alkalising and mineralising system. With a 12-litre capacity (4L + 8L configuration), it's designed for larger households wanting remineralised, alkaline water.
However, the fluoride removal is only partial at approximately 90% — notably lower than WatersCo's 99.9%. The system also uses a plastic top section (BPA-free), meaning some plastic contact with water occurs during filtration.
The complex consumable system with multiple replaceable components (filters need replacing every 4–6 months, plus ceramic and other parts on variable schedules) drives annual maintenance costs to approximately $200–$350 — more than double WatersCo's estimated running cost.
Despite higher annual maintenance costs, Zazen offers genuinely comprehensive multi-stage technology with alkalising and mineralising benefits — representing better value than competitors charging similar prices for basic filtration.
Pros
Comprehensive multi-stage system
Remineralisation and alkalising options
Large 12L capacity
2-year warranty (varies)
90-day money-back option
Cons
Only ~90% fluoride removal (partial — no dedicated fluoride stage)
Top section is plastic (BPA-free, but still plastic contact)
Complex consumables with many replaceable parts to track
High annual maintenance cost: $200–$350/year
Filters need replacing every 4–6 months

alps
alps water filter 12l
Ceramic/stoneware • Large capacity • Budget-friendly entry
value for money score
3.5/5
alps water filter 12l
The Alps water filter offers decent capacity at a lower price point, making it attractive for budget-conscious buyers. The ceramic and stoneware construction provides reasonable build quality.
However, its fluoride removal capability is not explicitly stated — a significant concern for health-conscious buyers specifically seeking verified fluoride reduction. Without clear lab testing data confirming fluoride, heavy metal, and forever chemical removal rates, it's difficult to recommend over alternatives with proven, published performance.
The ceramic dome and cartridge require replacement every 6–9 months, with annual maintenance costs around $200–$250.
Pros
Large 12L capacity
Solid multi-stage design
Lower upfront price ($425)
Ceramic/stoneware construction
Cons
Fluoride removal capability not explicitly confirmed — likely limited
No dedicated fluoride stage
Regular 6–9 month replacements increase running cost
12-month warranty only (vessel)
Some plastic components
Annual maintenance ~$200–$250

big berkey
big berkey 8.5l
Stainless steel • Long-lasting elements • Fluoride requires PF-2 add-on
value for money score
3.5/5
big berkey
Big Berkey is renowned globally for durability and extremely long-lasting filter elements. The stainless steel construction is premium, and the Black Berkey elements can filter thousands of litres (approximately 11,356L each) — delivering very low per-litre costs over the filter's lifetime.
However, fluoride removal requires purchasing the separate PF-2 add-on — adding significant extra cost and complexity to the system. For Australian buyers specifically wanting fluoride removal included out-of-the-box, this is a notable drawback.
The gravity-fed design also results in a slower fill rate, which can frustrate busy households accustomed to faster filtration.
Pros
Extremely durable stainless steel construction
Very low cost per litre over time
Black elements last thousands of litres
Premium finish
5-year warranty on stainless parts
Cons
Fluoride removal requires separate PF-2 add-on purchase (extra cost)
High upfront investment
Gravity-fed system has slower fill rate
Element warranty varies

kyn & folk
dove 10l ceramic filter
Handcrafted ceramic • UltraCeram fluoride option • Artisan design
value for money score
3.5/5
kyn & folk dove 10l
Kyn & Folk offers a handcrafted ceramic benchtop water filter with excellent fluoride removal when paired with the UltraCeram candle option. (approximately 99%+). The high-fire ceramic stoneware construction and artisan aesthetic is genuinely impressive.
However, the limited warranty (manufacturing defects only), slower ceramic flow rate, and variable replacement candle costs reduce its practical appeal for everyday family use. Ceramic candles typically last 6–12 months depending on usage and water quality.
At ~$550 with uncertain long-term support, WatersCo's lifetime warranty and proven 40-year track record offer significantly more security for your investment.
Pros
Beautiful handcrafted ceramic stoneware design
Excellent fluoride removal with UltraCeram option (~99%+)
High-quality artisan construction
10L capacity
Cons
Limited warranty (manufacturing defects only)
Slower flow rate typical of ceramic filters
Replacement candles can be pricey
Variable maintenance costs
Fluoride removal requires specific UltraCeram candle selection

earths water
9l glass benchtop filter
Borosilicate glass + bamboo • Elegant design • Alkaline filtration
value for money score
2.5/5
earths water 9l glass
Earths Water offers one of the most visually striking designs on the market with borosilicate glass and bamboo accents. However, the premium price tag ($599–$799) is difficult to justify given the extremely basic filtration technology and the shortest filter lifespan of any system we tested.
At approximately 350 litres per cartridge (~3 months), you'll replace filters around 4 times per year. This is the most frequent replacement schedule in our entire comparison — creating ongoing hassle and cost that quickly adds up. For the premium price point, we expected significantly more advanced technology and longer filter life.
Pros
Large 9L glass tank
Elegant borosilicate glass + bamboo design
Good fluoride reduction (~98%)
Alkaline water output
Cons
Extremely high purchase price for basic filtration technology
Shortest filter life of all tested (~350L / ~3 months)
Most frequent replacement schedule in comparison
Basic filtration despite premium pricing
12-month warranty only (vessel)
Poor value for money compared to alternatives

stefani
stefani 10l glazed ceramic
Budget entry-level • Basic filtration • Available at Bunnings
value for money score
2.5/5
stefani 10l glazed ceramic
The Stefani is a basic ceramic benchtop water filter available for just $99. If you simply want basic sediment and chlorine filtration at the absolute lowest possible upfront cost, it does that job.
However, Stefani does NOT remove fluoride — a critical consideration for most Australian health-conscious buyers seeking comprehensive water purification. It offers basic filtration only, minimal warranty/support, and the glazed ceramic construction is functional but basic.
The cheap replacement cartridges (~$50/year) keep ongoing costs low, but you get what you pay for in terms of filtration performance. The cartridge lasts approximately 6 months (350–600 litres).
Pros
Very low upfront cost ($99)
Cheap replacement cartridges (~$50/year)
Readily available at Bunnings
Simple operation
Cons
DOES NOT remove fluoride
Basic filtration only
Minimal warranty/support
Cartridge only lasts ~6 months (350–600L)
No multi-stage filtration
Does not alkalise or mineralise water

Frequently Asked Questions
What is the best benchtop water filter in Australia?
The "best" option depends on what you value most — fluoride removal, filter longevity, build quality, or budget. In our comparison of top water filter bench top systems in Australia, WatersCo offered the strongest balance of contaminant removal (99.9% fluoride), filter lifespan (up to 4 years), and long-term value, while several other brands performed well in more specific areas such as price or design.
Do all benchtop water filters remove fluoride?
No. Some popular filters like Stefani (available at Bunnings for $99) do not remove fluoride at all. Others like Zazen offer only partial removal (~90%). WatersCo achieves 99.9% fluoride removal using their patented nano carbon compound — the highest verified rate we tested. Big Berkey requires a separate PF-2 add-on purchase for fluoride capability, adding extra cost and complexity.
How does a benchtop filter compare to a reverse osmosis water filter benchtop system?
Unlike a reverse osmosis water filter benchtop system that strips ALL minerals (including beneficial ones) and requires electricity, WatersCo's gravity-fed multi-stage filtration removes contaminants while preserving and adding beneficial minerals. RO systems also waste significant water and have higher maintenance costs.
What's the difference between a benchtop filter and a whole home water filtration system?
A whole home water filtration system filters all water entering your house (showers, laundry, etc.) and requires professional plumbing installation. Benchtop filters like WatersCo focus on drinking water only, require no installation, and offer more advanced multi-stage purification at a lower cost.
How long do benchtop water filter cartridges last?
This varies significantly by brand. WatersCo filters last up to 4 years (12,000 litres), making them the longest-lasting in our test. In comparison: Earths Water requires replacement every ~3 months, Zazen every 4–6 months, Alps every 6–9 months, Kyn & Folk every 6–12 months, and Stefani every ~6 months. Longer filter life means lower annual maintenance costs and significantly less hassle over time.
What's the difference between WatersCo and Zazen?
Both offer multi-stage filtration with alkalising benefits, but there are key differences. WatersCo provides higher fluoride removal (99.9% vs ~90%), significantly longer filter life (3–4 years vs 4–6 months), lower annual maintenance cost ($90–150 vs $200–350), a lifetime warranty (vs 2 years), and an all-glass reservoir where no plastic contacts the filtered water (vs Zazen's plastic top section). WatersCo also has a longer track record with 40+ years in Australia.
Is the Stefani filter from Bunnings any good?
Stefani is the most affordable option at $99 with cheap ongoing maintenance (~$50/year). However, it does NOT remove fluoride and offers only basic sediment and chlorine filtration with a glazed ceramic design. If fluoride removal is important to you — as it is for most health-conscious Australian families — Stefani won't meet your needs. It's suitable only for those wanting the absolute cheapest entry point who aren't concerned about fluoride or advanced contaminant removal.
Are glass reservoir filters better than plastic?
Glass reservoirs ensure no plastic ever contacts your filtered water, eliminating concerns about microplastics or chemical leaching over time. WatersCo uses hand-blown silica glass with BPA/BPB/BPS-free housing — no plastic touches the filtered water at any stage. Some competitors like Zazen use a plastic top section (BPA-free but still plastic contact), while Big Berkey uses stainless steel and Kyn & Folk/Stefani use ceramic. For those prioritising purity, glass is generally the preferred choice.
What warranty should I expect from a quality water filter?
Warranties vary significantly. WatersCo offers a lifetime warranty on structure and parts — the only brand in our test to do so. Big Berkey offers 5 years on stainless parts. Zazen offers 2 years. Earths Water and Alps offer only 12 months on the vessel. Kyn & Folk covers manufacturing defects only. Stefani has minimal/unspecified warranty. A longer warranty generally indicates manufacturer confidence in build quality and longevity.
How do I choose between the top water filter brands?
Consider these key factors: (1) Contaminant removal — What do you want removed? If fluoride is a priority, verify the removal percentage is 99%+. (2) Filter lifespan — How often do you want to replace filters? Longer = less hassle and often lower annual cost. (3) Materials — What contacts your water? Glass is preferred over plastic for purity. (4) Warranty — Lifetime warranty indicates manufacturer confidence. (5) Total cost of ownership — Calculate costs over 3–5 years, not just upfront price. Based on these criteria, WatersCo ranked #1 in our testing.
