A jug is the first filter most Australians buy, and for one job it is the right choice: it takes the chlorine taste out of tap water for under fifty dollars and no plumbing. Everything else about jugs is a compromise, and it pays to know which ones you are accepting.
What a jug does and does not do
Every jug here uses a granular activated carbon cartridge, some with an ion-exchange resin for limescale and metals. That reduces chlorine, taste, odour and, in Brita’s case, some lead and copper. None of them remove fluoride, dissolved salts or nitrates, and none is a safety filter for tank or untreated water. If that is your problem, a jug is the wrong product.
Capacity is about the filtered half, not the total
A “3.5 litre” jug holds about two litres of filtered water below the cartridge and a litre and a half waiting above it. Filtering takes several minutes, so a jug suits a household that tops it up through the day, not one that wants two litres instantly for a pot of pasta.
Cartridge costs are the real price
The jug is cheap. The cartridges are not. Brita Maxtra Pro cartridges were $15.95 single or $61.49 for six at Bunnings when we checked, so about $10 each in a pack. At a change every four weeks that is roughly $130 a year. Aquaphor’s Maxfor+ cartridges are cheaper and fit most Maxtra-style jugs. If you are going to filter for years, an on-tap unit at $50 with a $40 annual cartridge or an under-sink system will cost less from the second year.
The picks
The Brita Marella XL wins because of the ecosystem: cartridges in every Woolworths, Coles and Bunnings, a reminder on the lid, and three cartridges in the box so you are covered for about three months. The Aquaphor Compact is the pick if fridge space is tight or you want cheaper cartridges. The Cuckoo 3.8 L uses a carbon block rather than loose granules and holds the most, but it will not fit a fridge door and its cartridges are online-only. The Stefani 2 L is the cheapest way to try filtered water at all.

Frequently asked questions
How often should I change a Brita cartridge?
Brita rates Maxtra Pro at about 150 litres or four weeks, whichever comes first. A household drinking two litres a day will hit the litre limit in about ten weeks, so most people are changing on the four-week timer rather than on volume.
Do jug filters remove fluoride or PFAS?
Standard jug cartridges do not remove fluoride. Some newer Brita listings claim PFAS reduction; treat any such claim as unverified unless the product shows NSF/ANSI 53 or P473 certification for it. For fluoride, see our reverse osmosis guide.
Can I use generic cartridges in a Brita jug?
Yes. The Maxtra shape is widely copied, and Aquaphor's Maxfor+ cartridges are one example. Generic cartridges are usually cheaper; the trade-off is that the filtration claims are the generic maker's, not Brita's.
Are water filter jugs worth it?
For chlorine taste and smell, yes, and they are the cheapest way to try filtered water. For anything else, a plumbed or on-tap filter is better value within a year because jug cartridges are the dearest way to buy carbon.
