One filter at the mains looks after every tap in the house.
An under-sink filter only treats the kitchen tap. A Puretec whole-house system is fitted where the mains water enters your property, so your kitchen, showers, baths, laundry and outdoor taps all run filtered water.
Your O'Brien® or Laser® plumber checks your home, water and pressure, recommends the right system, and installs it to Australian Standards.
Reduces the chlorine taste and smell at every tap, including the one you fill the kettle from.
Less chlorine in the shower and bath can help with dry skin and hair.*
Less sediment means fewer blockages in tapware, hot water systems and appliances. FilterWall™ F4 and F6 also manage scale build-up.
With filtered water on tap you can stop buying bottled water and leave the slabs at the shop.
All three are Puretec Tier-1 systems built for Australian and New Zealand conditions and backed by a 10-year warranty.* Choose the one that suits your home, or let your plumber recommend it.
Reliable two-stage filtration in a straightforward format.
The same proven filtration, with an architectural aluminium cover.

See how each system sits against different walls, gardens and finishes.
Your plumber fits the filter where the mains water enters your property, so it usually sits on an outside wall near the water meter. FilterWall™ and the WH2-55AMC are made to live outdoors, and your plumber will talk you through the best spot on your home.

Puretec requires a licensed plumber to install its whole-house systems and keep the warranty valid, and every O'Brien® and Laser® member is licensed.
We check your water pressure, pipework and number of bathrooms so the system keeps up when every tap is running.
Cartridges typically last 6 to 12 months. We'll remind you and swap them with genuine Puretec parts.

An under-sink filter treats water at one tap. A whole-house system is installed where the mains water enters your property, so every tap, shower, bath and appliance gets filtered water.
Yes. Puretec requires a licensed plumber to install its whole-house systems at the mains entry point, and a professional install keeps your warranty valid. Your local O'Brien® or Laser® member handles the whole job.
Usually every 6 to 12 months, depending on how much water your household uses and the quality of your local supply. We can book it in for you.
No. A water softener removes the minerals that cause hard water. ScaleProtect™ on FilterWall™ F4 and F6 leaves them in and changes how they behave, so scale is easier to clean and you get less spotting on glass and shower screens. For water harder than about 140 ppm, your plumber may suggest adding a Puretec water softener.
Not when it's sized correctly. Each system is rated up to 55 L/min (FilterWall™ F3 and F4 up to 30 L/min) and is designed to keep performing when several taps are running. We'll match the system to your home's size and pressure.
All three systems carry a 10-year warranty: one year parts and labour plus nine years parts only. Cartridges aren't covered. FilterWall™ custom colours carry a two-year finish warranty.
That depends on the system, your pipework and where it's being installed. Your local member will give you a clear, no-obligation quote after looking at your home.
Choosing a water filter is easier with someone who knows what to look for. Your local O'Brien® or Laser® plumber talks it through with you, then looks after the install.
