Best Water Filters for Purified Drinking Water in Australia

Choosing the best water filter for purified drinking water in Australia depends on your water source, taste preferences, budget, maintenance expectations and the contaminants you want to reduce.

For many homes on treated town water, the main goal is better-tasting drinking water with less chlorine taste and odour. For homes using rainwater tanks or bore water, the right system may need sediment filtration, UV treatment, reverse osmosis or other specialist filtration based on water testing.

The best water filter is not always the most expensive system. It is the filter that matches your water quality, your household’s daily usage and the level of filtration you actually need.

Installed Today lets customers compare water filters, drinking water filtration systems, kitchen water filter systems, reverse osmosis systems, UV water filter systems, whole home water filtration, shower water filters, water filter cartridges and service kits, water quality test kits and 3-way kitchen mixer taps online.

Quick answer: what is the best water filter for purified drinking water?

For most Australian homes, the best drinking water filter depends on the water problem.

If you mainly want better-tasting drinking water, start with a drinking water or kitchen filter. If you want more advanced filtration for dissolved solids, compare reverse osmosis. If your water source is tank or bore water, test first.

What does “purified drinking water” actually mean?

“Purified drinking water” is often used to describe water that has been filtered to reduce unwanted taste, odour, particles or selected contaminants.

However, not every filter purifies water in the same way. A carbon filter, reverse osmosis system and UV system all work differently.

A drinking water filter may help reduce:

• Chlorine taste

• Chlorine smell

• Sediment

• Rust particles

• Dirt and grit

• Some odours

• Some selected chemicals

• Some dissolved solids where reverse osmosis is used

• Microbiological risk where UV is correctly used with proper pre-filtration

The exact result depends on the system, cartridges, membrane, UV lamp, water pressure, water source and maintenance.

Why Australian homes use drinking water filters

Many Australian households choose water filtration because tap water can have taste, smell or quality issues even when it looks clear.

Common reasons include:

• Chlorine taste

• Chlorine smell

• Metallic taste

• Sediment in tap water

• Cloudiness

• Tank water concerns

• Bore water concerns

• Hard water scale

• Better coffee and tea flavour

• Less reliance on bottled water

• Filtered water for cooking

• Better water for family drink bottles

For town water homes, the main reason is often taste and odour. For tank and bore water homes, filtration should be based on water testing.

Best water filter for chlorine taste and smell

If your tap water tastes or smells like chlorine, a carbon drinking water filter is usually the first option to compare.

Carbon filtration is commonly used to improve:

• Drinking water taste

• Chlorine smell

• Coffee flavour

• Tea flavour

• Ice taste

• Cooking water

• General kitchen water quality

For this type of need, compare drinking water filtration systems or kitchen water filter systems.

A carbon filter is often simpler than reverse osmosis when the main issue is chlorine taste and odour.

Best water filter for kitchen drinking water

If you want filtered water at the kitchen sink, a kitchen water filter system is usually the most practical choice.

Kitchen water filters may suit:

• Families filling drink bottles

• Coffee and tea drinkers

• Homes reducing bottled water use

• Cooking and food preparation

• Everyday drinking water

• Rental properties

• Airbnb and short-stay homes

• Kitchen renovations

A kitchen system is usually installed under the sink and connected to a dedicated filtered tap or compatible mixer setup.

Best water filter for finer drinking water filtration

Reverse osmosis is often compared when customers want finer drinking water filtration.

A reverse osmosis system uses a semipermeable membrane to reduce dissolved solids and selected contaminants. It is usually installed under the kitchen sink with a dedicated filtered drinking water tap.

Reverse osmosis may suit homes wanting:

• Fine drinking water filtration

• Reduced dissolved solids

• Better drinking water taste

• Filtered water for cooking

• Filtered water for coffee and tea

• A more advanced kitchen water filter

• Less reliance on bottled water

Reverse osmosis systems need regular cartridge and membrane replacement. They also produce wastewater as part of the filtration process.

Compare options in the reverse osmosis collection.

Best water filter for tank water drinking

Rainwater tank water should be tested before choosing a drinking water filter.

Tank water may contain:

• Sediment

• Organic matter

• Leaf debris

• Roof debris

• Colour

• Odour

• Microbiological risk

• Low pH

• Metals from roof or pipework

A tank water drinking setup may need sediment filtration, carbon filtration and UV treatment depending on the water test result.

UV treatment may be suitable where microbiological risk needs to be managed, but UV works best when water is already clear and correctly pre-filtered.

Compare options in the UV water filter systems collection.

Best water filter for bore water

Bore water should always be tested before choosing a filter.

Bore water may contain:

• Hardness minerals

• Iron

• Manganese

• Salts

• Sediment

• Odour

• Metals

• pH issues

• Microbiological risk

A standard drinking water filter may not be enough for bore water. Some bore water can quickly clog filters or damage membranes if the wrong system is installed.

Start with testing. A water quality test kit can help identify what needs to be addressed before choosing a filter.

Best water filter for the whole home

A whole home water filter treats water as it enters the property, before it reaches taps, showers, laundry, appliances and kitchen outlets.

Whole home filtration may suit homes wanting:

• Filtered water at multiple taps

• Reduced chlorine smell in showers

• Less sediment entering appliances

• Better general water quality

• Cleaner water for bathrooms and laundry

• Filtration before kitchen and shower outlets

• A whole-house approach instead of one filtered tap

A whole home system is different from a kitchen-only drinking water filter. If your issue affects showers, bathrooms, laundry and appliances, whole home filtration may be the better category to compare.

Compare options in the whole home water filtration collection.

Best water filter for showers

A shower water filter treats water at a single shower outlet.

It may suit homes where the main concern is:

• Chlorine smell in the shower

• Shower water feel

• Sediment at one shower

• Strong treated-water smell

• Hair and skin feel after showering

• A simple shower-only filter option

A shower filter does not treat kitchen drinking water, laundry water, bathroom basins or appliances. If you want water filtered throughout the home, compare whole home filtration instead.

Best water filter setup for a kitchen renovation

If you are renovating a kitchen, it is worth planning filtered water before finalising the tap and sink layout.

A 3-way kitchen mixer can supply hot, cold and filtered water from one tap body when connected to a compatible filter system.

This may suit kitchens where you want:

• A cleaner sink layout

• No separate small filter tap

• Filtered drinking water at the main mixer area

• Less tap clutter

• A modern kitchen finish

• A compatible under-sink filtration setup

The mixer tap itself does not filter the water. It needs to be connected to a suitable water filter system.

Compare options in the 3-way kitchen mixer taps collection.

Reverse osmosis vs carbon drinking water filters

Reverse osmosis and carbon filters are both popular, but they suit different needs.

If your main issue is chlorine taste, carbon filtration may be enough. If you want more advanced drinking water filtration, compare reverse osmosis.

Does a water filter remove bacteria?

Not every water filter removes or treats bacteria.

A standard carbon drinking water filter should not be relied on as a bacteria treatment system. If bacteria or microbiological risk is a concern, especially with tank water or bore water, water testing is important.

UV treatment may be used where microbiological treatment is required, but it must be installed with suitable pre-filtration and maintained correctly.

Does a water filter remove heavy metals?

Some water filters can reduce selected heavy metals, but not all cartridges are designed for this.

If lead, arsenic, mercury or other metals are a concern, test the water and choose a system specifically rated for the contaminant.

Do not assume every water filter removes every heavy metal.

Does a water filter remove fluoride?

Many standard carbon filters do not remove fluoride.

Reverse osmosis is commonly compared for fluoride reduction, but performance depends on the membrane, water pressure, water quality and maintenance.

If fluoride reduction is important, check the product specifications before choosing.

Does a water filter remove hard water?

Most standard drinking water filters do not soften hard water.

Hard water is usually caused by calcium and magnesium minerals. It can leave scale on taps, shower screens, kettles and appliances.

For hard water, compare:

• Water softeners

• Scale-control systems

• Water conditioners

• Whole home hardness treatment

• Reverse osmosis for drinking water only

A reverse osmosis system may reduce minerals at one drinking water tap, but it will not protect the whole home from scale.

Water filters vs bottled water

A good drinking water filter can reduce reliance on bottled water.

Benefits may include:

• Less plastic waste

• Lower bottled water purchases

• Filtered water on demand

• Easier drink bottle filling

• Less storage space

• Better water for coffee and tea

• More convenient drinking water at home

The actual saving depends on the filter system price, cartridge replacement cost and how much bottled water your household currently buys.

Water filters for coffee and tea

Filtered water can improve coffee and tea when chlorine taste, odour or sediment are affecting flavour.

Filtered water may help with:

• Espresso machines

• Kettles

• Tea

• Plunger coffee

• Cold brew

• Ice

• Sparkling water machines

• Cooking water

If you are serious about coffee, think about the final water taste. Some people prefer carbon-filtered water, while others prefer reverse osmosis with remineralisation.

Water filters for families

Family homes usually need a system with good flow, enough cartridge capacity and simple maintenance.

Families may benefit from:

• Drinking water filtration systems

• Kitchen water filter systems

• Larger cartridge capacity

• Easy cartridge replacement

• Filtered water for school bottles

• Filtered water for cooking

• Better-tasting tap water

• Less reliance on bottled water

A small, low-capacity filter may not suit a busy family kitchen.

Water filters for rental properties

Rental properties need simple and reliable water filter systems.

For rentals, consider:

• Who replaces cartridges

• Cartridge replacement cost

• Maintenance schedule

• Tenant instructions

• Leak protection

• Easy filter access

• Filter tap labelling

• Replacement cartridge availability

A filter that is not maintained can lose performance, so keep the maintenance plan clear.

Water filters for Airbnb and short-stay homes

A drinking water filter can improve guest experience in short-stay accommodation.

It may help provide:

• Better-tasting drinking water

• Less need for bottled water

• Filtered coffee and tea water

• A premium kitchen feature

• Clear filtered tap labelling

• Easy guest use

• Reduced plastic bottle waste

For Airbnb properties, simplicity and reliability matter. Guests should not need to understand complex filtration controls.

How to choose the best drinking water filter

Before choosing a water filter, check these points.

1. Water source

Is your home on town water, rainwater tank water, bore water or a mixed supply?

2. Main concern

Are you trying to fix taste, smell, sediment, hardness, bacteria risk, dissolved solids, metals or something else?

3. Drinking water only or whole home?

Choose kitchen filtration for drinking water. Choose whole home filtration if showers, laundry, appliances and multiple taps are affected.

4. Water testing

If you are unsure what is in your water, test it before choosing a filter.

5. Flow rate

A filter should provide enough water for your household without frustrating slow flow.

6. Maintenance

Check cartridge cost, cartridge availability and replacement frequency.

7. Installation requirements

Check space, pressure, tap requirements, drainage for reverse osmosis, power for UV, and installer requirements.

Water filter installation considerations

Installation depends on the type of system.

Before ordering, check:

• Under-sink space

• Whole home filter location

• Water pressure

• Flow rate

• Pipe size

• Tap hole availability

• Drain connection if reverse osmosis is used

• Power point if UV or pump-assisted systems are used

• Cartridge access

• Weather protection for outdoor filters

• Installer requirements

Plumbing work should be completed by a licensed professional where required.

Water filter maintenance

All water filters need maintenance.

Maintenance may include:

• Sediment cartridge replacement

• Carbon cartridge replacement

• Reverse osmosis membrane replacement

• UV lamp replacement

• Service kit replacement

• O-ring checks

• Leak checks

• Pressure checks

• System sanitising where required

Compare replacement options in the water filter cartridges and service kits collection.

How often should water filter cartridges be replaced?

Replacement timing depends on:

• Water source

• Household usage

• Sediment level

• Chlorine level

• Cartridge capacity

• Number of filter stages

• Water pressure

• Flow rate

• Manufacturer instructions

Some cartridges may need replacement every few months. Others may last longer. Always follow the product maintenance schedule.

Common mistake: choosing a filter without testing

If you have tank water, bore water, hard water, staining, odour or a specific contaminant concern, test before buying.

A water test helps you avoid choosing a filter that does not solve the real problem.

Common mistake: assuming every filter removes everything

Different filters do different jobs.

A carbon filter may help with chlorine taste but not fluoride. A sediment filter removes particles but not dissolved chemicals. UV can treat microbiological risk but does not remove sediment or chlorine. Reverse osmosis can reduce dissolved solids but needs maintenance and produces wastewater.

Choose based on the water issue.

Common mistake: buying reverse osmosis when carbon is enough

Reverse osmosis can be excellent for finer drinking water filtration, but it is not always required.

If the only issue is chlorine taste and odour, a carbon drinking water filter may be simpler, easier to maintain and more cost-effective.

Common mistake: using a kitchen filter for a whole house issue

A kitchen water filter only treats one tap. It will not filter showers, laundry, bathroom taps, outdoor taps or appliances.

If the issue affects the whole home, compare whole home filtration.

Common mistake: forgetting replacement cartridges

A water filter only works properly when cartridges are replaced on time.

Before choosing a system, check:

• Cartridge price

• Replacement frequency

• Cartridge availability

• Number of stages

• Warranty requirements

• Service kit requirements

A cheap filter can become frustrating if cartridges are hard to find or expensive to replace.
