How to Choose the Right Water Filter Tap for Your Kitchen

If you are installing an under-sink or reverse osmosis system, choosing the dedicated tap that goes with it is a small but genuinely practical decision.

Style and Finish

Filtered water taps come in finishes to match most kitchen tapware, from chrome through to brushed nickel and matte black, so this is largely a matter of matching your existing fittings.

Single Temperature vs Multi-Function Taps

Basic filtered taps deliver only filtered cold water, while integrated 3-way mixer taps combine filtered water with your existing hot and cold mains supply from a single fitting, saving a second tap hole.

Mounting Considerations

Check how many pre-drilled holes your sink or benchtop has available, since this affects whether a separate filtered tap or an integrated mixer tap is the more practical choice.

Flow and Practicality

A slightly taller gooseneck-style spout can make filling jugs and pots easier than a low-profile tap, which is worth considering based on how your household actually uses the kitchen sink.

The Engineering Behind How to Choose the Right Water Filter Tap for Your Kitchen

Understanding how to choose the right water filter tap for your kitchen comes down to a handful of measurable engineering factors: micron rating (the physical pore size of the filter media, typically between 0.5 and 20 microns for residential systems), flow rate (litres per minute the system can sustain without a noticeable pressure drop), and media type (sediment, carbon block, catalytic carbon, KDF, or membrane). Each of these interacts with your home’s plumbing, incoming water pressure, and household demand to determine real-world performance.

Reputable manufacturers publish independent test data for these specifications rather than relying on generic marketing claims. When comparing systems, look for components that are WaterMark certified for plumbing compliance in Australia and, where a specific contaminant reduction claim is made (such as chlorine taste and odour, cysts, or PFAS), verify it against the NSF/ANSI standard the claim is tested to.

Verified Standards & Further Reading

For homeowners who want to verify the certification claims made in this article, we encourage you to check the primary sources directly rather than taking any supplier’s word for it (including ours):

• Search any plumbing product’s WaterMark certification status directly on the Australian Building Codes Board’s official WaterMark product database.
• Verify NSF/ANSI certified water treatment products and the specific standard they are tested against via the official NSF certified product listings.
• Read the current Australian Drinking Water Guidelines published by the National Health and Medical Research Council for the official national standards on drinking water quality.

All AquaCo filtration systems supplied and installed by Vic Water Filters carry WaterMark Licence No. 23448 and are independently tested to the relevant NSF/ANSI standards for their stated contaminant reduction claims, including PFAS/PFOA and PFOS reduction where specified on the individual product datasheet.
