What Does Whole House Filtration Exactly Do for Your Home?

Whole house filtration covers every outlet in your home

A whole house water filter system treats mains water before it enters your home. Every tap, shower, laundry outlet and appliance receives filtered water from the same source at the point of entry.  

Many Perth households want better quality water throughout their home, not just at the kitchen tap.

Chlorine taste, sediment like sand and grit, odour and hard water scale are some of the most common water quality concerns across Perth and regional WA. The challenge is that these issues are not all caused by the same thing, and they are not treated in the same way.

Understanding how whole house filtration works and the options available to achieve complete home filtration is the key.

What a whole house water filter does

Standard whole house filter systems use a combination of sediment and carbon filtration.

The sediment filter removes dirt, rust, sand and other fine particles and the carbon filter reduces chlorine, chlorine by-products and contaminants and improves the taste and smell of water across the home.

The result is improved water quality from every outlet, including kitchen taps, showers, laundries and outdoor taps.

In Perth, many homeowners notice the benefits most in their shower water and drinking water. In regional WA and the Pilbara, sediment filtration often plays an even bigger role.

Some whole house filtration systems also include scale reduction filters to help reduce hard water scale buildup. While these systems help manage the effects of calcium and magnesium, the minerals remain in the water. 

As with all filtration systems, water filter cartridges need replacing regularly to protect water quality and maintain performance. We recommend replacement every 6 to 12 months, depending on the quality of your source water and how much water you use.

Our whole house filters and water softeners range shows the systems we install and service across WA.

What whole house filtration does not do

Not all whole house filter systems are designed to solve every water problem.

A standard sediment and carbon whole house water filter improves water quality by reducing chlorine, sediment and contaminants. It is designed to improve the taste, smell and quality of water throughout the home.

Hard water scale is a separate issue. The calcium and magnesium that cause scale remain dissolved in the water and pass through standard sediment and carbon filters largely unchanged. These minerals are responsible for the white marks that appear on taps, shower screens, tiles and appliances.

Where scale buildup and water quality are concerns, a whole house filter system can be paired with additional water hardness treatment. Some whole house filtration systems include scale reduction filters which help reduce scale buildup by changing how calcium and magnesium behave in the water.

For homes with significant hard water issues, a whole house filtration system combined with a water softener provides the highest level of hardness treatment by reducing calcium and magnesium before water reaches taps, appliances and hot water systems.

Where scale is already the main concern at home, water softeners for Perth covers how softeners work alongside whole house filtration. 

When whole house filtration is the better fit

A whole house water filter system is often the best choice when the same water quality issues affect multiple areas of the home. 

If chlorine taste and odour are noticeable in drinking and shower water, treating the water at the point of entry improves every outlet simultaneously.  Where hard water scale is also a concern, scale reduction filters or a water softener can be incorporated into the system.

Many Perth homes use a combination of filtration and water softening to achieve what we describe as genuine complete home filtration.

Water quality can vary significantly across Perth, the Pilbara and regional WA. The right solution depends on your water source, how much water you use and what you want to improve.
