Mavis Carruthers has a background as a registered nurse, naturopath and is now co-founder of WestOz Water Filters. With over 40 years of combined healthcare experience – including Clinical Nurse Specialist in orthopaedics at Royal Perth Hospital and operating her own naturopath wellness centre in Cannington – Mavis brings a genuine health-first perspective to everything WestOz does.When Mavis and her husband Rob established WestOz Water Filters in 2019, the goal was simple: empower interested Western Australian families to filter their own water, backed by honest advice rather than a sales pitch. Today, more than 1,700 customers trust WestOz Water Filters, which was named Best Home-Based Business at the 2025 Belmont & WA Small Business Awards.Beyond work, Mavis grows her own vegetables, collects eggs from her chooks, enjoys the competition of lawn bowls, dances Nia most mornings and travels regional Australia with Rob in their motorhome.
