One thing worth understanding before you compare: a certification number tells you WHAT was tested, and the numbers are not interchangeable.

Our 6 picks for the best water filters in Australia

#1Top pick

BRITA

BRITA Marella XL Water Filter Jug 3.5L

Best for most homes

The honest answer for most homes.

Check price on Amazon AU

Amazon.com.au listing checked on . The details here were read from it on .

Capacity3.5 litres total (2.0 litres filtered)
Included4 MAXTRA PRO cartridges
Certification (stated)NSF certified
TargetsChlorine reduction
MaterialBio-plastic
Dimensions14.8L x 25.8W x 25.8H cm

Pros

  • Four cartridges in the box
  • Aimed squarely at chlorine taste
  • No plumbing, no power, and it moves house with you

Cons

  • A jug is a manual routine — you have to remember to refill it
#2

Waterdrop

Waterdrop C1S Countertop Reverse Osmosis System

Best reverse osmosis

The reverse-osmosis pick. It gives you multi-stage RO without drilling under the sink, and Waterdrop publishes an efficiency figure — but read the certification for what it is: 372 is about the materials, not the output.

Check price on Amazon AU

Amazon.com.au listing checked on . The details here were read from it on .

Filtration6-stage reverse osmosis
Certification (stated)NSF & ANSI 372 (lead-free materials)
Efficiency (stated)3:1 pure to drain ratio
ControlsSmart touch screen
Capacity1.1 gallons
Dimensions39.7L x 27.7W x 42.8H cm

Pros

  • Six-stage RO with no plumbing or installation required
  • Waterdrop states a 3:1 pure-to-drain ratio
  • Auto-rinses the filter on power-up

Cons

  • Large on a benchtop at 42.8cm tall
  • Its NSF/ANSI 372 listing certifies lead-free materials, not contaminant removal
#3

iSpring

iSpring Counter-top Drinking Water Filter

Best simple counter-top

The middle path. If a jug is too slow but reverse osmosis is more than you need, this handles sediment, rust and chlorine taste from a unit that takes almost no bench space.

Check price on Amazon AU

Amazon.com.au listing checked on . The details here were read from it on .

TypeCounter-top, cartridge included
Testing (stated)ANSI, NSF external testing certification
TargetsSand, silt, sediment, rust; chlorine taste and odour
Dimensions12.7D x 12.7W x 35.6H cm

Pros

  • Narrow 12.7cm footprint
  • Targets sediment and rust as well as chlorine taste

Cons

  • Single-stage — it is not doing what the RO units do
  • Connects to the tap, so it is less mobile than a jug
#4

Devanti

Devanti Benchtop Water Filter 14L Gravity Purifier

Best for renters

The renter's answer, and the one to take camping or to a place with unreliable supply. No electricity, and a genuine multi-stage cartridge.

Check price on Amazon AU

Amazon.com.au listing checked on . The details here were read from it on .

Capacity14 litres
TypeGravity — no electricity, no plumbing
FiltrationCeramic, activated carbon and mineral layers
Suits (stated)1-3 people
Dimensions33L x 27W x 59H cm

Pros

  • Needs no power and no plumbing at all — pour water in the top
  • 14 litres is far more standing capacity than a jug

Cons

  • 59cm tall, so it needs clear space under a cupboard
#5

Kuvings

Cara CA3001 Benchtop RO Water Filter with Hot & Cold

Best all-in-one

Buy it if you want filtered water hot and cold on demand. The nine temperature settings are the real feature — it is a kettle, a chiller and an RO filter in one box.

Check price on Amazon AU

Amazon.com.au listing checked on . It had no buy button that day, so it may be unavailable. The details here were read from it on .

FiltrationDual-stage reverse osmosis
Temperatures9 settings, 4°C to 98°C
MonitoringReal-time TDS display
Capacity5.5 litres
Dimensions41L x 23W x 41H cm

Pros

  • Replaces a kettle and a filter in one appliance, from 4°C to 98°C
  • Real-time TDS monitoring shows what the filter is doing
  • Plumbing-free benchtop installation

Cons

  • Cara's '99.9% of contaminants' figure is the manufacturer's own claim
#6

Waterdrop

Waterdrop WD-A2 Countertop Reverse Osmosis System

Waterdrop names PFOA and PFOS in its own specification.

Check price on Amazon AU

Amazon.com.au listing checked on . The details here were read from it on .

Filtration5-stage RO, 0.0001μm membrane

Pros

  • 0.0001μm membrane

How to choose the best water filters in Australia

  1. 1Learn what the certification number means. NSF/ANSI 372 — which the Waterdrop C1S lists — certifies that the materials are lead-free, NOT that the unit removes anything.
  2. 2Match the format to your housing. A jug or gravity filter needs no plumbing and comes with you when you move — the Devanti runs with no electricity at all. Countertop RO units sit on the bench.
  3. 3Count the ongoing cost, not just the purchase. The BRITA Marella XL includes four MAXTRA PRO cartridges in the box.
  4. 4Check the capacity against your household. The Devanti's 14 litres is described by its own listing as suiting 1-3 people; the Cara CA3001 holds 5.5 litres but dispenses hot and cold on demand, which changes how you use it.
  5. 5If you want hot water too, look at the combination units. The Cara CA3001 lists nine temperature settings from 4°C to 98°C, which replaces a kettle and a filter jug in one appliance.

Editor's note

NSF/ANSI 372 — the one the Waterdrop C1S lists — certifies that the materials are lead-free, which says nothing about what the unit removes.

Our take

Start with the BRITA Marella XL unless you have a specific reason not to. Take the Devanti if you rent, the iSpring if you want something small, and the Waterdrop C1S if you genuinely want reverse osmosis.

Frequently asked questions

What do the NSF numbers on a water filter actually mean?

They tell you what was tested, and they are not interchangeable. The BRITA listing says its MAXTRA PRO filter was tested according to NSF/ANSI 53 for reducing PFAS. 372 — listed by the Waterdrop C1S here — certifies that the materials themselves are lead-free, not that the filter removes anything.
