Is a Tap Water Filter Worth It for Chlorine Taste and Odour?
Quick answer: For most Australian households, a tap water filter is worth it if chlorine taste or odour is your main concern. A quality tap filter attaches directly to your existing tap, is simple to install, and is designed to reduce chlorine and associated taste and odour at the point of use. Compared to a filter jug, it delivers filtered water on demand without refilling; compared to an under-sink system, it costs far less and requires no plumbing changes.
Why Chlorine Taste and Odour Is a Common Complaint in Australian Tap Water
Australian tap water is treated to meet the Australian Drinking Water Guidelines (ADWG), which are set by the National Health and Medical Research Council (NHMRC). Chlorination is the most widely used disinfection method across Australian water utilities, and it plays an important role in keeping reticulated water safe from microbial contamination during distribution.
However, chlorine and its by-products can leave a noticeable taste and odour in tap water, particularly when water has travelled through older pipes or when chlorine levels are higher after treatment events. Many households find this affects the enjoyment of drinking water and cooking. This article explains how tap filters work, how they compare to other options, and what to look for when choosing one.
How Tap Water Filters Work to Reduce Chlorine Taste and Odour
Tap water filters use activated carbon or a combination of filter media to reduce chlorine and associated taste and odour as water passes through the cartridge at the point of use.
Activated carbon adsorption
Activated carbon is the most common filtration medium for chlorine taste and odour reduction. It works through adsorption: chlorine molecules in the water bind to the large internal surface area of the carbon as water flows through. Granular activated carbon (GAC) and carbon block formats are both widely used, with carbon block generally offering a finer filtration path. The effectiveness of activated carbon for chlorine reduction is well established and referenced in standards such as NSF/ANSI 42, which covers aesthetic effects including taste and odour. Note that referencing NSF/ANSI 42 here is general context only; always check the specific product specifications for the filter you are considering.
Sediment pre-filtration
Many tap filters also include a sediment stage designed to reduce particulate matter such as rust and fine particles that can contribute to discolouration and off-tastes. Sediment filtration typically uses a mechanical barrier rated by micron size. Check the product specifications for the micron rating of any filter you consider.
What tap filters are not designed to do
A standard tap filter is not a medical device and is not intended to diagnose, treat, cure, or prevent any disease. It is designed to improve the aesthetic qualities of tap water, specifically taste and odour, depending on your water conditions. It does not replace the disinfection function of your water utility, and it does not address all possible water quality concerns. If you have specific water quality concerns beyond taste and odour, consult your local water authority or a licensed water quality professional.
Tap Filter vs Filter Jug vs Under-Sink: Which Option Is Right for You?
Each filtration format has genuine trade-offs. The right choice depends on your household size, budget, rental situation, and how much filtered water you use each day.
| Feature | Tap Filter | Filter Jug | Under-Sink System |
|---|---|---|---|
| Installation | Attaches to existing tap; no plumbing | No installation needed | Requires plumbing; often professional install |
| Filtered water on demand | Yes, instant flow | No, must pre-fill and wait | Yes, instant flow |
| Suitable for renters | Generally yes | Yes | Often no (permanent modification) |
| Upfront cost | Low to moderate | Low | Moderate to high |
| Ongoing cartridge replacement | Yes, periodic | Yes, frequent | Yes, periodic (less frequent) |
| Counter/bench space used | Minimal (on tap) | Fridge or bench space | Under-sink cabinet space |
| Flow rate | Moderate (check specs) | Slow (gravity) | High |
| Primary use case | Drinking and cooking water at the tap | Drinking water (small volumes) | Whole-kitchen filtered water |
For most Australian renters and homeowners who want filtered drinking and cooking water without plumbing changes, a tap filter offers the best balance of convenience, cost, and performance for chlorine taste and odour reduction.
How to Choose a Tap Water Filter: A Buying Checklist
Use this checklist to narrow down your options before purchasing. No single filter suits every household, so consider each factor against your own situation.
- Check your local water report: Your state or territory water authority publishes annual water quality reports. Knowing your local chlorine levels and any other parameters of interest helps you choose the right filter media. Contact your utility or visit their website for the latest data.
- Confirm tap compatibility: Tap filters attach to the aerator thread of your tap. Check whether your tap has a standard thread size and whether an adaptor is included or available. Some designer or pull-out taps may not be compatible.
- Consider your daily water volume: If your household uses large volumes of filtered water for cooking and drinking, check the filter's rated flow rate and daily capacity in the product specifications.
- Review cartridge life and replacement cost: Cartridge life is typically rated in litres or months. Factor in the ongoing cost of replacement cartridges when comparing options.
- Look for relevant standards as general context: Standards such as NSF/ANSI 42 (aesthetic effects, including taste and odour) are useful reference points. Always verify whether a specific product has been tested or certified to any standard by checking the product specifications directly.
- Rental or ownership situation: If you rent, confirm that attaching a tap filter does not breach your tenancy agreement. Most tap filters are non-permanent and leave no damage.
- Filtration media: Activated carbon block generally offers finer filtration than granular activated carbon for taste and odour. Check the product specifications for the media type used.

Frequently Asked Questions
Is a tap water filter worth it in Australia?
For most Australian households, yes. Australian tap water is safe to drink as supplied by your utility, but chlorine used in disinfection can leave a noticeable taste and odour. A tap filter is designed to reduce chlorine taste and odour at the point of use, is simple to install, and does not require plumbing changes. Whether it is worth it depends on how much the taste and odour of your tap water bothers you and how much filtered water your household uses daily.
Will a tap filter remove all contaminants from my water?
No. A standard tap filter is designed to reduce chlorine and associated taste and odour, depending on your water conditions. It is not designed to address all possible water quality concerns, and it does not replace the disinfection function of your water utility. If you have specific concerns about your water quality beyond taste and odour, contact your local water authority or a licensed water quality professional. Always check the product specifications for what a specific filter is designed to reduce.
How often do I need to replace the filter cartridge?
Cartridge replacement frequency varies by product and depends on your water usage and local water conditions. Most tap filter cartridges are rated by a volume in litres or a time period in months, whichever comes first. Check the product specifications for the cartridge life of the filter you choose, and follow the manufacturer's replacement schedule to maintain performance.
Can I use a tap filter if I rent?
In most cases, yes. Tap filters attach to the aerator thread of your existing tap and do not require permanent modifications to plumbing or fixtures. They can generally be removed without leaving any damage. It is always a good idea to check your tenancy agreement or confirm with your property manager before installing any fitting, even a non-permanent one.
What is the difference between a tap filter and a filter jug?
A tap filter delivers filtered water on demand directly from your tap, with no need to pre-fill or wait. A filter jug uses gravity filtration and must be filled manually and stored in the fridge or on the bench. For households that use filtered water for both drinking and cooking, a tap filter is generally more convenient. Filter jugs suit smaller volumes and lower budgets but can be slow and require frequent refilling.
Does a tap filter affect water pressure or flow rate?
Most tap filters cause a modest reduction in flow rate compared to unfiltered tap flow, because water passes through the filter media. The degree of reduction varies by product. Check the product specifications for the rated flow rate of any filter you are considering, and compare it to your household's needs.
