Southern Filtration — family-owned water filtration specialists serving Wollongong & the Illawarra
About us

A local family helping Illawarra homes drink better water

Southern Filtration is a family-owned business specialising in water filtration for homes across Wollongong, Shellharbour, Kiama, Dapto & the wider Illawarra. We test, install, service and stand behind every system we fit.

Water filtration, done properly.

We started Southern Filtration because too many households were putting up with water that tasted like chlorine, left residue on fixtures and dried out their skin. Our focus is simple: understand what's actually in your water, then install the right filtration to remove it.

Whether you're on town water in Wollongong or running a rainwater tank further out, we'll test your supply for free, explain the results honestly, and recommend a whole-house system, reverse osmosis unit or upgrade that suits your household — nothing more.

How we work

Four principles every job runs on.

These aren't slogans — they're how we run every install and every service call across the Illawarra.

PRINCIPLE · 01

Family-owned, not a franchise

You deal directly with the people who test your water and install your system — start to finish, same faces.

PRINCIPLE · 02

Test first, recommend second

We test your supply before we suggest anything, so you only pay for the filtration your water actually needs.

PRINCIPLE · 03

Whole-home thinking

Filtration isn't just about drinking water. Showers, laundry, appliances and skin all benefit from treating the water at the main line.

PRINCIPLE · 04

Neat, professional installs

Tidy plumbing, clean site, system pressure-tested and demonstrated to you before we pack up.

Kieran and Kristen were so lovely to deal with. My husband and I are so pleased with the new water filtration system installed by Southern Filtration — from the communication to the efficiency and attention to detail. I cannot fault the service that was provided. As a young family of 5, clean water supply was a priority and we are extremely happy we chose Southern Filtration for the job. Would highly recommend to anyone wanting to install filtration into their household!

I recently had a whole house water filtration system installed in my home by Southern Filtration and I couldn't be happier with the service I received. From start to finish, the process was smooth, and the team was professional, knowledgeable, and friendly. They took the time to explain the installation process and made sure I was fully satisfied before leaving. The pricing was competitive, especially considering the high quality of service and the peace of mind I now have knowing my water is clean and safe. Highly recommend this company.

I highly recommend Kieran and his partner Kirsten - they were both wonderful to deal with. We had a filtration system installed around two months ago and noticed the difference in our water immediately.
