Best water filter jug: Brita Marella XL


  • Large capacity
  • Easy-to-use flip-top lid


  • Doesn't fit in all fridge doors
  • May be too heavy for some people's liking

Price (RRP): $37

Buy at Amazon
Buy at Brita
Buy at The Good Guys

Why we chose it

If you're searching for a water filter jug that allows you to drink chilled, filtered water whenever you want, the Brita Marella XL is an excellent option. With its 3.5-litre capacity, it's more than large enough to quench the whole family's thirst, plus it's dishwasher safe (except the lid) and has been designed to fit in the fridge door.

The Marella XL has also picked up a host of positive reviews from Australian consumers, including from customers at retailers like Amazon and The Good Guys. As a result, it's our top pick as the best water filter jug.

The Marella XL is BPA-free, measures 26.5 (w) x 14.8 (d) x 27.5 (h) cm, and features Brita's MAXTRA+ filter to reduce chlorine, metals and minerals that cause limescale. Its contoured handle provides grip, while the flip-top lid ensures easy pouring.

It also has an in-built electronic indicator to let you know when it's time to replace the filter – every 150 litres or approximately once a month. When you need to replace the MAXTRA+ filter, a single replacement is priced at $15.50. However, you can buy in bulk and save a little money, with 2-, 3-, 4- and 12-pack options available.

Some reviewers do point out that this jug is too large to fit in their fridge door. If that's the case, we'd recommend checking out the standard version of the Marella, which has a smaller 2.4-litre capacity but has also earned plenty of positive customer reviews.

But if you've got space in your fridge for the Marella XL, it's definitely worth a closer look.

This, combined with the fact that it's available from multiple Australian retailers, makes the Brita Flow Water Filter Cask our pick as the best water filter dispenser for large families.

With its large 8.2-litre total capacity, including 5.2 litres of filtered water, the Flow is designed to fit on your benchtop or on a shelf in your fridge. Just make sure to check the measurements first (30.7W x 22.6H x 21.5D cm) if you plan on putting it in your fridge, as it may not fit in all appliances.

This system uses a MAXTRA+ filter to reduce chemicals, heavy metals and limescale from your water. A built-in electronic indicator lets you know when it's time to replace the filter, while the built-in tap ensures that it's always easy to fill your glass. There's also a sliding lid so that filling up the dispenser with fresh water is a breeze.

Best under-sink / inline water filter: Filtered Water Solutions Twin Under Sink System

  • Dedicated tap for filtered water


  • Not the cheapest
  • Some customers complain about annoying reminders to buy replacement filters

Price (RRP): $549

Why we chose it

If you're in the market for an under-sink water filter, the Filtered Water Solutions Twin Under Sink System has certainly been well received by Aussie consumers. With an average rating of 4.4/5 from over 65 customer ratings on productreview.com.au, it's our top pick as the best under-sink or inline water filter.

This system features the combination of a 1-micron sediment filter and a 0.5-micron carbon filter to help eliminate contaminants, chemicals and other unwanted nasties from your drinking water. In the first stage of the filtering process, the sediment filter removes dirt, dust, rust, algae and other particles.

Water is then passed through the carbon filter cartridge, which is designed to remove chlorine and other chemicals, pesticides, heavy metals and more. This stage of the process also removes unpleasant tastes and odours, resulting in water that's not only meant to be free of contaminants but that also tastes better. This compact filtration unit fits under your kitchen sink, with a special filtered water tap installed above the sink.

If you want to take things a step further, Filtered Water Solutions also offers a three-stage under-sink model that adds a superfine inline filter as the third stage of filtration. The purpose of this activated carbon filter is to absorb impurities and eliminate any chlorine taste from water.

But if you're searching for a practical under-sink system, it's hard to go past the Filtered Water Solutions Twin Under Sink System. It's also worth mentioning that despite the $550 RRP quoted above, this system was on sale for around $250 at the time of writing.

This unit also comes with a handy LCD display that indicates the remaining capacity before you'll need to change the filter. Expect 600 litres (or around four months) of use, while replacement filter cartridges retail for around $36.

How do you clean a water filter jug or bottle?

Cleaning your jug or bottle is simple and easy. The most care and attention should be taken when rinsing and drying it.

The easiest way to clean your water filter jug is to first remove the filter and thoroughly clean the inside with soap and water. Once this is done, it’s best to wipe the jug down and then allow it to air dry. At this stage, if your filter is due for a change, then put a new one in. If not, you can continue with inserting the old filter back into the jug.

How often should you change the filter on your jug or bottle?

This can vary and it depends on the kind of water filter jug you have. With a standard water filter jug, the filter should be replaced every two to three months. Other models on the market are designed to be long lasting, and these filters can be replaced every six months.
