Why Perth Homeowners Are Switching to Under-Sink Water Filters

Why do homeowners choose under-sink water filters?

The benefits of an under-sink water filter go beyond better-tasting water.  Homeowners choose under-sink water filters to reduce chlorine and chlorine by-products, remove contaminants like pesticides and organic compounds that affect taste and smell, along with sediment like grit, sand and fine particles and to enjoy unlimited access to filtered drinking water.

Our entry-level Twin Filter Systems use sediment and carbon filters and start from $500, with free standard domestic installation included in many areas of Perth and regional WA.

The filter cartridges need replacing every 6 to 12 months to maintain system performance and protect drinking water quality. 

Providing enough drinking water often means spending too much on plastic water bottles, more bench clutter, lost fridge space and running to the store for supplies. 

An under-sink filter connects to the mains water and sits under the bench. Filtered water comes from the tap when you need it.

For most WA homes, the case rests on three things: better-tasting water at the tap, lower spending, and less to manage.

1. Better-tasting water from the kitchen tap

Unpleasant taste and smell are the most common reasons Perth homeowners ask about filtered drinking water.

A standard under-sink filter reduces chlorine used for disinfection, chlorine by-products, organic contaminants and sediment which can all affect the taste, clarity and smell of water at the kitchen tap. 

For homes on mains water, better-tasting water is the first change customers notice after installation.

Perth mains water is disinfected with chlorine before it reaches the tap. The WA Department of Health sets acceptable chlorine levels in the mains water supply.

Data from the Water Corporation shows that Perth’s water comes from a mix of desalination, groundwater and surface water which is why water taste can vary from suburb to suburb.

Movers from Melbourne and the east coast notice the difference clearest the first time they travel back home. 

Perth water runs harder and more chlorine-heavy than many east-coast supplies. Once a filter is in place, tea, coffee, cooking water and drink bottles all come from the same tap.

Our under-sink water filter guide gives the full background on how these systems work.

2. Fewer bottles, less spending and filtered water on demand

In many Perth households from Subiaco to Joondalup, bottled water slowly becomes part of the weekly shop. Not by choice, but because the tap does not taste right, so bottles fill the gap.

The ongoing cost adds up faster than households expect. An under-sink solution shifts that spend to one up-front cost and a filter change every 6 to 12 months.

Plastic waste is the other side of the same habit. Western Australians have returned more than 3.5 billion drink containers under the state’s deposit scheme with bottled water making up  a large proportion. 

Every bottle bought to avoid the tap is single-use plastic that a filter makes unnecessary. 

Switching to filtered tap water cuts the ongoing cost and reduces the amount of plastic waste your household generates.

3. Knowing exactly what changes and what does not

Peace of mind comes from matching the filter system to the problem. 

A standard under-sink filter system reduces chlorine, and removes unwanted chemicals, dirt, and other sediment to improve the taste, clarity and odour of your tap water. 

Scale buildup in kettles, shower screens and appliances comes from calcium and magnesium, not chlorine, and you need specialist scale -reduction filters or a dedicated water softener to tackle this.

Installing a whole house filter system with a water softener removes chlorine, contaminants and sediment throughout the home and removes calcium to soften water. 

4. A filter that keeps working with the right care

What keeps filtered water clean and tasting good is regularly replacing the filter cartridges. 

How often filters need changing depends on how much water you use and the quality of the source water.

We recommend replacing under-sink water filter cartridges every 6 to 12 months and we’ll remind you when it’s time to change your filters.

We change filters as part of our regular service to keep your drinking water tasting great and making sure your filter system performs as it should.

Which under-sink filter suits your water?

The right solution depends on the problem you want to fix.

Our standard Twin Filter System is a two-stage sediment and carbon water filter system which is ideal for Perth homes on municipal mains water.

Our Twin Heavy Metal Filter System suits homes where lead, copper or other heavy metals in the water are a concern. We’ll only recommend this system if the quality and taste of your source water requires that level of filtration.

The Maxiflow Scale Reduction Filter System uses a single, sediment and carbon filter which will help break down calcium and manage scale build up at the tap, but it will not make the water soft.

If water quality issues extend beyond the kitchen tap, a whole house filter system may be more appropriate. We install and service a full range of home water filtration solutions across Perth and regional WA.

Is an under-sink filter worth it for your home?

For most Perth homes on municipal mains water, yes.

An under sink filter system suits homes where the main goal is a constant supply of great-tasting filtered drinking water from the kitchen tap.

It also makes sense when jugs and bottled water have become a tiresome and expensive part of your weekly routine.

Entry-level under-sink filter solutions start at around $500 and will last several years with regular maintenance and filter replacement. 

The average Australian spends over $500 every year on bottled water and the environmental cost of single use plastic waste is even higher.
