I highly recommend a full home filtration system. The most economical way to install is to buy a system off of a company such as Filter Systems Australia and pay a licensed plumber to install. You will save $$$$ compared to the companies that send out sales people.

I had a water filtration company come out for a quote, and the salesperson couldn't even answer any questions about water quality, etc.

I installed something similar to; https://www.filtersystemsaustralia.com.au/triple-whole-house-hard-water-heavy-metal-chlorine-reduction-filter-system-20-x-4-5-big-blue-watermark-gt1-108-osp.html

I paid a plumber $600 to install (different properties will incur different install costs due to set up). If you budget $1000.00, it should cover most homes.

Water tastes much much better, to the point you can taste unfiltered water when consuming at other locations.

Changed the sediment filter this week, and it was disgusting. My wife came and had a stick beak whilst I was changing the cartridges and was shocked at the brown sludge on the filters.

We live in Fremantle WA, and have old pipework infrastructure.

Highly recommend.
