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.

Had entire house filtration installed and could not recommend Southern Filtration enough. Professional, efficient and super clean installation (no mess left and very tidy). Water is distinctly different in taste!!
