I bought this product because it was very reasonably priced and the filter combination was specific for our WA hard water. Great product, very professional looking, commercial grade hardware. There were a couple of hand screws to hold the cover on that were missing so I texted Shield and they put them in the post straight away. They also answered all my mounting questions straight away with photos of other installs. I highly recommend this product and I am very particular. Tip - I rang up to query the difference between this product (3 stage filtration for WA water with stainless steel cover) versus a cheaper model, glad I did because this one has a full stainless steel frame underneath the cover, a lot more robust.
Bought 3 water filter replacement, installed it myself
No dramas and a lot cheaper than outside..
Highly recommended…
This came very quick was easy to install and works great!! Top system.
I get all my filters from here also got a reverse osmosis system from here.
These guys are great and always so helpful.

We purchased this filter unit for our caravan. It seems a solid unit and is working very well. We're confident we're drinking pure water that tastes great, while we're on the road.
We've experienced all sorts of water quality during our journeys and it's nice to have the peace of mind that our stomachs won't have an adverse reaction to the water we drink.
I am very pleased with the filters

Great so far very easy to install
Filters were straightforward to order and easy to find the right parts. Delivery was fast. Only criticism might be that there was not an option to buy a 1yr supply, but it’s not a big thing to store under the sink
I ordered a set of filters. Delivery was very fast and the product works as expected. Thanks for the good service. 👍
Order came quickly. Everything was ok .
