Your water filtration system is typically installed under the kitchen sink.

Installation is carried out by a trained Kinetico professional with the plumbing expertise to fit your system correctly. Beforehand, a Kinetico expert will visit your home to assess your plumbing and ensure everything is ready for a smooth installation on the day.

The process is usually quite quick, depending on the complexity of your plumbing.

Find out more about our installation process

We recommend routine maintenance and sanitisation of your Kinetico K5 Pure water filter to ensure it continues to operate at optimum performance.

The lifespan of each filter cartridge will vary depending on household water usage. For an average family of four, the typical lifespan is around 9–12 months. The pre-filter, taste & odour cartridge, and any auxiliary cartridges should be replaced annually, or sooner if the filter timer indicates.

Before carrying out any maintenance, ensure your hands are clean. For complete peace of mind, we suggest having a Kinetico service engineer perform a professional filter change and sanitisation.

If replacing the filters yourself, please follow the instructions in the user manual. Always wash your hands before handling new filters and avoid touching the internal parts. After installation, flush the system by running a full tank of water through the tap, and carefully check for any leaks.

Why do I need a water filter?

A water filtration system removes a range of impurities – including chlorine and microplastics – from your household water supply. These contaminants can affect everything from the taste of your drinking water to your health, cooking, and even your home’s plumbing.

By trapping and removing these contaminants, a Kinetico water filter ensures you receive pure, clean water at the turn of a tap.
