Inline Fridge Filter vs Under-Sink Filter — Which Do You Need?
Many Sydney households that have a fridge water dispenser ask whether they need an inline fridge filter, an under-sink filter, or both. The answer depends on how you use water in your home:
If your primary concern is the quality of water from your fridge — chilled water, ice — then an inline fridge filter addresses that directly. It targets the water supply to the fridge and filters it before it reaches the dispenser or ice maker.
However, it doesn't filter the water from your kitchen tap — the water you use for cooking, making tea and coffee, or filling a glass directly. For a complete solution, most Jean-Paul customers who have a fridge dispenser choose to install both an inline fridge filter and an under-sink filter in the same visit. This covers fridge water, drinking water and cooking water from a single installation booking.
For the most comprehensive solution, an under-sink reverse osmosis system can be plumbed to supply both the kitchen tap filter point and the fridge water line simultaneously — so a single RO system filters both your tap water and your fridge dispenser. Jean-Paul will advise on the right configuration for your kitchen at the time of booking.
Inline Fridge Filter Maintenance
Inline fridge filter cartridges should be replaced every 6 to 12 months depending on your water usage and Sydney's incoming water quality. Cartridge replacement is a simple DIY process — the cartridge housing is accessible and replacement requires no tools or plumber. Jean-Paul demonstrates the process and provides a recommended replacement schedule at installation.
