Scott Muir is the owner of Waters Co Australia - a company that's been around since the 1970's with superior filtration and science behind. I've personally had one of their filters since 2016. This episodes covers what you need to know and look for when buying a water filter and why (because whats in the tap water is a bit scary)
Waters Co Australia is having an EOFY sale until July 1st - which you can access at watersoaustralia.com.au
For full home filtration systems Scott mentions Easy Waters Solution
