Key takeaways
- A filter improves taste, smell and sediment. It is not a fix for a supply you believe is unsafe, so raise that with your water supplier first.
- Under-sink filters treat drinking and cooking water at one tap. Whole-of-house filters treat every outlet and protect appliances, but need more space and upkeep.
- Installing a filter on the water supply is licensed water plumbing work in NSW.
- Overdue cartridges drop pressure and stop doing their job, so put the change date in your calendar.
