Not yet rated

Pros

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

Cons

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

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.

  • Dedicated tap for filtered water

Cons

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

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.

Brita claims that the On Tap Advanced Water Filter System reduces 99.99% of bacteria, particles such as microplastics, chemicals and metals in your drinking water.

The system offers multiple settings – filtered water, stream and shower – to suit different water usage needs, and it's easy to switch over to unfiltered water whenever required.

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.

So if you're looking for a convenient and affordable way to get filtered water straight from your tap, there are lots of good reasons to check out the Brita On Tap Advanced Water Filter System.

How to compare water filters

It's a good idea to compare a range of products before you buy. This will ensure that you choose the best water filter for your needs.

Make sure you consider the following factors when comparing your options.

Type of filter

The first thing you need to do is decide on the type of filter you want and the filtration method. To do this, you'll need to consider factors such as bench and cupboard space in your kitchen, what impurities or contaminants you want to remove from your tap water, and your budget.

Size and available space

If you're simply looking to have some chilled, filtered water available throughout the day, a jug filter might be the easiest solution. If you need to filter large amounts of water, you may decide that an under-sink model is the best choice. You'll also need to consider the dimensions of any filter you're considering and the available bench or under-sink space.

Certification

Make sure any water filter you choose meets the relevant Australian standard. AS/NZS4348 covers several common contaminants, while you can find public health standards for a range of other filters from NSF International.

Pore size

This is the size of the holes in a filter that water passes through, measured in microns. However, be sure to check whether the pore size measurement provided is "absolute" or "nominal/mean", as the latter only refers to the filter's average pore size.

Flow rate

Check the filter system's flow rate to get an idea of how much filtered water it can provide in litres per minute.

Cartridge replacement

If the water filter you choose features replaceable cartridges, check how often those cartridges need to be replaced and how much they cost.

Warranty

Check the length of the manufacturer's warranty and exactly what it covers.

Cost

Jug and on-tap water filters are the cheapest options, with entry-level jugs available for around $20. Desktop models generally sit in the $50-$350 price range, while under-sink systems can cost anywhere from $250 to more than $1,000.

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.


Key facts about water filters:

  • If you don't like the taste of the water that comes out of your taps at home, or if you're worried about its quality, a water filter can help.
  • By removing contaminants from your drinking water, a water filtration system can help improve the quality and taste of water.
  • There are several factors to consider when choosing a water filter including the type of filter and the capacity.
  • Prices can range anywhere from $20 for a basic filter jug to several-hundred dollars for an under-sink filter.

What is a water filter?

Water filters remove dirt, sand and other impurities from water. However, the way they work and the impurities they remove can vary depending on the type of filter medium you choose.

For example, many filters use a method known as adsorption. This typically involves the use of an activated carbon filter to remove contaminants that stick to the carbon's pores. According to the CDC in the US, activated carbon filters are effective at removing metals such as lead.

Ion exchange water filters remove minerals from hard water to soften it, while distillers boil water to kill bacteria and eliminate other contaminants.

Then there are reverse-osmosis filters, which pass water through a semipermeable membrane and through filters to remove a wide range of contaminants. However, this process produces a large amount of wastewater.

The right filtration method for you will vary depending on what impurities or contaminants you want to remove from your water.

What types are available?

If you want to start filtering your drinking water, there are a few different filtration options available.

Water filter jugs and counter-top filters

The simplest (and often the cheapest upfront) option is to buy a water filter jug. These don't require any installation – just fill the jug up from the tap and store it in your fridge – and it's easy to change the filter when needed. However, you will need to contend with the ongoing cost of filter replacements.

If you'd like to filter larger quantities of water at a time, you may opt for a counter-top urn. This is another convenient option as it doesn't require any plumbing work, but it will take up precious bench space in your kitchen.

On-tap filters

Your next option is to buy a water filter that can be mounted to your tap. These small and convenient filters filter the water as it runs through your faucet, and they're easy and inexpensive to fit. You can also switch to unfiltered water whenever you want.

However, you'll need to ensure that one of these filters will fit properly on your tap, while you'll also have to put up with a slower flow of water when you choose filtered.

Under-sink filters

The most expensive option is to install an under-sink water filter. This requires plumbing work and will take up cupboard space under your sink, but it's also a long-term solution capable of filtering large quantities of water. If you need to use a lot of filtered water, this is an option well worth considering.

Depending on the model you choose, you may replace your existing tap or require the installation of a separate tap for filtered water. Some models can also produce chilled and sparkling water for drinking.

4 things to consider

There are a few other factors you should consider before buying a water filter:

  1. Do you really need it? Tap water in Australia is generally perfectly safe to drink. For more information on the work that goes into ensuring the quality of drinking water, check out the Australian Drinking Water Guidelines. But if you're on a private water supply, or you're worried about the taste or additives of tap water, you may still decide that a water filter is the right choice for you.
  2. Issues with bottled water. If you're unhappy with the taste or quality of tap water, you might consider drinking bottled water whenever possible. However, not only is this prohibitively expensive, there's also the environmental impact to consider. So if you're looking to improve the quality of the water you drink, it's well worth considering a water filter instead of relying on bottled water.
  3. Plumbing work. If the filter you choose needs to be plumbed in, make sure the work is carried out by a licensed plumber. Otherwise, you not only run the risk of the filter not functioning properly but also voiding your warranty.
  4. Follow the manufacturer's instructions. To ensure that your filter is as effective as possible, follow the manufacturer's instructions closely. This includes replacing filter cartridges when recommended and staying on top of any regular servicing tasks.

If you're ready to start shopping for water filters, here's where to buy water filters online in Australia.
