Filtered water taps for cleaner drinking water at the sink
Filtered water taps are kitchen mixer taps with a filtration system built into the tap or connected underneath the sink, delivering filtered drinking water straight from the same spout you use for washing up. They remove the need for a separate filter jug or a second dedicated tap, since many models combine hot, cold and filtered water in one fitting. This makes them a practical option for anyone wanting better-tasting water without adding another hole to the benchtop or another unit to the fridge door.
3-in-1 and 4-in-1 systems explained
A 3-in-1 tap combines filtered, hot and cold water through the one spout, while a 4-in-1 or multi-function tap adds boiling or chilled water as a fourth option. The filtration itself usually happens through a cartridge fitted under the sink, which the tap draws from via an internal or separate lever. Nero Tapware and Oliveri both offer filtered tap systems in this style, ranging from simpler 3-in-1 mixers through to more advanced multi-function units for kitchens that want boiling water on demand as well.
What to check before buying
Filtered water taps need enough space under the sink for the filter cartridge and, in the case of boiling or chilled models, a small tank or heating unit as well. Measure the cabinet space before choosing a system, and check whether the tap uses a standard filter cartridge that is easy to replace locally, since ongoing filter changes are part of owning one of these taps. It is also worth matching the tap's finish, such as chrome, brushed nickel or matte black, to the rest of your kitchen tapware and hardware.
Installation and filter maintenance
Most filtered taps are installed the same way as a standard kitchen mixer, with the filtration unit plumbed in separately underneath. A plumber can usually fit one during a kitchen renovation or as a standalone upgrade to an existing sink. Filter cartridges typically need replacing every six to twelve months depending on water quality and usage, so check the manufacturer's guidance for your specific model once it is installed.
Who filtered water taps suit
These taps suit households that drink a lot of tap water and want to reduce chlorine taste or particulates without buying bottled water or refilling a jug filter. They are also a common addition during a full kitchen renovation, since the plumbing and cabinetry work is already underway. If you are simply after a standard kitchen mixer without built-in filtration, a regular kitchen tap will do the job without the extra cartridge and installation considerations.

Frequently Asked Questions
What is a filtered water tap?
A filtered water tap is a kitchen mixer tap connected to an under-sink filtration cartridge, so filtered drinking water comes out of the same spout as your regular hot and cold water. Many filtered water taps combine three or four functions in one fitting, removing the need for a separate filter jug or dedicated filter tap.
What is the difference between a 3-in-1 and 4-in-1 filtered water tap?
A 3-in-1 filtered water tap delivers hot, cold and filtered water from the one spout. A 4-in-1 adds a fourth function, usually boiling or chilled water, for households that want on-demand hot water for tea and coffee as well as filtered drinking water.
How often do I need to change the filter in a filtered water tap?
Most filter cartridges need replacing every six to twelve months, depending on how much water your household uses and local water quality. Check the specific guidance for your tap model, since replacement intervals vary between systems from Nero Tapware, Oliveri and other brands.
Can a filtered water tap be installed in an existing kitchen?
Yes, in most cases a plumber can fit a filtered water tap and its under-sink filtration unit into an existing kitchen without major renovation work. You will need enough cabinet space under the sink for the filter cartridge and, for boiling or chilled models, a small tank as well.
Do filtered water taps remove chlorine taste from tap water?
Filtered water taps are designed to reduce chlorine taste and common particulates from mains water, giving cleaner-tasting drinking water straight from the tap. The exact filtration performance depends on the cartridge fitted, so check the specifications of the system you choose.
