A Quick Guide to Buying Water Filters
Choosing the right water filter comes down to what you want to remove from your water. Our Standard Setup is a great all-round option for Australian homes, helping reduce chlorine, chloramine, sediment and scale, while our Premium Setup takes filtration a step further with ultra-fine 0.2-micron filtration for added protection against PFAS, microplastics and heavy metals. Whichever setup you choose, all Pure₂O replacement filters use a universal 20″ x 4.5″ fitment, so you’re not locked into proprietary cartridges when it’s time for a replacement.
