Stage 1 – Sediment Filtration
The Shield® grooved sediment filter helps capture suspended particles and sediment before water reaches the finer filtration stages.

Stage 2 – PFAS & Chloramine Filtration
The Shield® coconut carbon block filter is designed to help reduce PFAS, chloramine and other unwanted substances.

Stage 3 – Carbon Block Filtration
The Hydrotech® 0.22 micron carbon block filter provides an additional filtration stage for water supplied throughout the home.

Whole House Water Filter for Rainwater

Homes using rainwater tanks can benefit from a multi-stage filtration setup designed to address sediment and other unwanted substances that may be present in stored water.

The three-stage system provides multiple filtration stages before water reaches household outlets, making it suitable for whole-house rainwater filtration applications.

Whole House Water Filter for Hard Water

For properties dealing with hard water and limescale, this system provides multiple filtration stages designed to address common water-quality concerns. The filtration setup can help reduce substances associated with scale, sediment and other unwanted water contaminants.

Free-Standing or Wall-Mounted Installation

The flexible mounting design allows the system to be installed according to the available space.

Free-standing installation is suitable where a dedicated floor or ground-level position is available.

Wall-mounted installation can be useful where floor space is limited and the filter system needs to be secured against a suitable wall.
