A 3-stage whole house water filter system is one of the most effective ways to improve the quality of water throughout your entire home. At Full House Water Filtration, we supply and install premium 3-stage filters designed specifically for Sydney residential properties.

Installed at your private water meter, these systems deliver cleaner, fresher water to every tap, shower, bathroom, laundry, and appliance in your home — supporting better water quality for your family and protecting your plumbing from impurities.

Why Choose a 3 Stage Water Filter System?

A 3-stage whole house filter provides three layers of protection, helping ensure consistent water quality for everyday use.

Stage 1
Sediment Filtration

Removes sand, dirt, rust, and particles that can clog appliances and fixtures.

Stage 2
Carbon Filtration

Reduces chlorine, chemicals, and unpleasant tastes or odours.

Stage 3
Fine Polishing or Heavy-Metal Reduction

Provides an additional level of refinement to further improve clarity and quality.

Together, these stages filter water down to 5 microns, achieving up to 97% purity, ideal for showering, cleaning, cooking, and general home use.

Important Information for Homeowners

Suitable only for standalone
homes with a private
water meter

A 3-stage whole house system can only be installed if your home has its own water meter at the front of the property.

Not suitable
for units or
apartments

Units share a water meter with the entire building and cannot support whole house systems.

Reverse Osmosis is the

Frequently Asked Questions

What is a 3-stage water filter system?

It is a whole house filtration setup using three stages (sediment, carbon, fine polishing) to improve water quality throughout the entire home, not just at one tap.

Can this system be installed in a unit or apartment?

No. Whole house systems require a private water meter. Units must use reverse osmosis instead.

Does a 3-stage filter remove fluoride and PFAS?

No. Only reverse osmosis removes fluoride and PFAS. A 3-stage whole house filter reduces chemicals and improves clarity, but does not eliminate dissolved contaminants.

How often do the filter cartridges need replacing?

Sediment filters: every 6–12 months
Carbon filters: every 12–24 months
Polishing filter: every 12–24 months

Will this affect my water pressure?

No, when properly sized and installed. We ensure the system matches your home’s required flow rate before installation.
