When it comes to choosing the best under-sink drinking water filter system for your home, there are a few things you need to consider.
How To Choose The Best Under Sink Drinking Water Filter System For Your Home
The most important factor is undoubtedly the quality of the water in your area.
If you have particularly hard water or if there are contaminants in your water supply, you’ll need a filter that can handle those specific issues.
Another thing to consider is how often you’ll need to change the filters.
Some filters need to be changed every few months, while others can last for up to a year or more. It’s also important to choose a filter that’s easy to install and doesn’t require too much maintenance.

Whilst we know the benefits and convenience of having high quality filtered drinking water on tap, regular maintenance and filter replacements are required to the quality of your filtered water remains high. So, how long do water filters really last? Below, find out how to keep your water filtration system running optimally, including the factors that determine how long do water filters last.
For over 30 years Billi has been supplying Australian households with high-quality water filtration systems. We pride ourselves on being at the forefront of water filtration technology with a range of innovative systems that are designed and made right here, in Australia. So you can continue to enjoy high-quality drinking water, here are the main factors that determine how long a water filter cartridge lasts
How To Look After Your Water Filtration System
When it comes to how long should a water filter last, we recommend that your cartridge is replaced every 12 months, however, some areas require a higher level of water filtration which means you may need to replace the filter more often – same if you have a high water usage.
The reason you need to replace filters is that they accumulate organic matter during the filtration process that builds up over time (which can lead to biofilm development). Each filter also has a litre capacity and once this is reached the filter needs to be replaced (or if the filter has been in place for 12 months – whichever comes first). All replacement filters for our water filtration systems have a 30,000-litre capacity (chlorine reduction).
Here is what water filter cartridges filter out of your water and why it is important to ensure your filter is working as it should:
- Chemicals (e.g. chlorine)
- Minerals
- Parasitic cysts including cryptosporidium and giardia
Home Water Filter Replacement
Billi’s house filter replacement service is available for any Billi Home system.
Our premium filters apply activated carbon fibre with minimal bonding as well as technologies like BWT’s Fibron X® media which has a superior contaminant reduction performance and capacity. The structure helps remove more than conventional carbon filters – which are made of granules and often held together with a resin – decreasing the surface area and therefore the quality of filtration.
Our premium house filter replacement cartridge service includes filters which have been certified to reduce:
- Particles in the water, and
- Chemicals (reducing chlorine and organic chemicals).
All while allowing minerals to flow through the appliance without scale or build-up. Also, our 0.2 Micron filters can reduce:
- parasitic cysts giardia
- cryptosporidium and;
- heavy metals.

With a graded density profile this technology ensures maximum performance and capacity so you can enjoy the very best drinking water quality.

When it comes to mixing tasty but easy non-alcoholic drinks to make at home, the secret often lies in the quality of the water used. In this guide, we’ll explore how Billi’s innovative water filtration systems transform ordinary tap water into a standout ingredient for your non-alcoholic summer party drinks.
The Role of Filtered Water in Non-Alcoholic Beverages

Creating your own healthier versions of soft drinks is easier than you might think, just add a splash of your favourite syrups – think elderflower, mint, or even spicy ginger– to give a tantalising twist to your sparkling water. It’s a perfect blend of fizz and flavour, minus the artificial additives and high sugar content of commercial soft drinks.
Easy Non-Alcoholic Drink Recipes with Billi Water
Sparkling Summer Berry Punch
- Ingredients: Fresh berries, lemon juice, honey, sparkling Billi water
- Method: Muddle the berries and mix them with lemon juice and honey. Top with sparkling water from your Billi system for a fizzy, refreshing punch.
Tropical Paradise Mocktail
- Ingredients: Pineapple juice, coconut water, lime, Billi chilled water
- Method: Combine pineapple juice, coconut water, and a squeeze of lime. Add ice and chilled water from your Billi system for a tropical twist.
Classic Homemade Lemonade
- Ingredients: Lemons, sugar, Billi filtered water
- Method: Mix freshly squeezed lemon juice with sugar. Add cold, filtered water from your Billi tap to balance the tangy lemon with a sweet, smooth finish.
Multi-stage Filtration for Better Taste
Despite Australia’s high standards of tap water quality, local factors like infrastructure changes, pollutant runoff, and household plumbing can affect the water’s chemical composition and contaminant levels. We understand the importance of cleanliness and great taste in every drop of water. That’s why we’ve collaborated with BWT, Europe’s largest water treatment products company, to bring you the best in water filtration technology.
Our premium filters are equipped with BWT’s innovative Fibron X® technology, which features a graded density profile for maximum performance and capacity. This advanced multi-stage filtration ensures that you receive water of the highest quality, consistent in its taste and perfect for dialling in your homemade drink recipes.

Easy Maintenance for Consistent Quality
Maintaining the quality of your Billi water system is straightforward and painless.
