What’s the Best Way to Fix Bad-Tasting Tap Water?

The fastest, most reliable way to fix bad-tasting tap water is a point-of-use activated-carbon filter fitted to your tap. Carbon filtration removes the chlorine, sediment and organic compounds that cause most “off” tastes and smells in seconds, as the water flows — without bottles, boiling or a plumber. Boiling, chilling and filter jugs can help a little, but they don’t tackle the main culprit (chlorine taste) as quickly or as cheaply over time.

Why does my tap water taste bad?

If your tap water tastes or smells off, it’s almost always one of these causes:

• Chlorine (“pool” taste or smell): Australian utilities add chlorine or chloramine to keep water safe from bacteria. It leaves a taste and odour many people dislike by the time it reaches your glass.
• Sediment, rust and “white flakes”: Older pipes and hot-water systems shed tiny particles that make water taste metallic or look cloudy.
• Trace metals: Copper or lead can leach from older household plumbing, giving a bitter or metallic edge.
• Staleness: Water that’s been sitting in the pipes overnight can taste flat.

What’s the best way to fix the taste? (Methods ranked)

1. Activated-carbon tap filter — best overall. Filters chlorine, sediment, microplastics and many contaminants on demand. Low cost per litre, no plastic waste, installs in minutes.
2. Filter jug — okay for small volumes. Helps with chlorine taste but is slow, needs refilling and takes fridge space.
3. Chilling in the fridge — a quick band-aid. Cold water masks chlorine taste but removes nothing.
4. Boiling — not for taste. Kills microbes but won’t remove chlorine taste once cooled.
5. Bottled water — expensive and wasteful. Clean taste but 40c–$1+ per litre and plastic waste.

How to fix bad-tasting tap water in 3 steps

1. Identify the cause — chlorine smell, cloudiness or a metallic taste each point to a different issue.
2. Fit an activated-carbon filter to your tap — one step handles chlorine, sediment, microplastics and more.
3. Replace the cartridge on schedule — roughly every six months, so the carbon keeps working.

Where a tap filter fits in

Filtering is optional rather than essential for safety on Australian mains water. If you do want to cut chlorine taste, sediment and microplastics, a point-of-use activated-carbon filter is one simple, low-cost option. PureFlow is one such tap-mounted filter, but the right choice depends on your water and your household — it is worth comparing the options and deciding what suits you.

Frequently asked questions

Why does my tap water suddenly taste different?
A sudden change usually follows mains work in your area (extra chlorine or stirred-up sediment) or a hot-water-system issue. A carbon filter smooths out these day-to-day changes.

Does boiling water remove the chlorine taste?
Boiling can drive off some chlorine, but it’s slow and won’t help with sediment, metals or microplastics. A carbon filter is faster and more complete.

Is bad-tasting water unsafe?
Not usually — Australian mains water is treated to meet the Australian Drinking Water Guidelines. Bad taste is mostly aesthetic. Read our water guide →
