A recent 7NEWS report has urged couples to consider filtering their tap water after PFAS chemicals were found, in research covered by the report, to potentially harm fertility. The story has prompted a wave of questions from homeowners about what PFAS actually is, how it ends up in drinking water in the first place, and what — if anything — can be done about it at the household level. Below, we break down what the report says, what PFAS is, and how reverse osmosis (RO) filtration fits into the picture.
What Is PFAS?
PFAS stands for per- and polyfluoroalkyl substances, a large family of manufactured chemicals that have been used since the 1950s in products designed to resist water, oil, stains, and heat. You'll find PFAS compounds in non-stick cookware coatings, waterproof fabrics and outdoor gear, food packaging, and firefighting foams used to suppress fuel fires. What makes PFAS particularly persistent is its chemical structure: the carbon-fluorine bonds that give these substances their non-stick, waterproof properties are also extremely stable, meaning they don't break down easily in the environment.
This durability has earned PFAS the nickname "forever chemicals." Because of their widespread industrial and consumer use over the past seven decades, PFAS compounds have been detected in some Australian water supplies, alongside similar findings in other countries with comparable industrial histories.
How Does PFAS Get Into Tap Water?
PFAS doesn't usually enter drinking water supplies through a single dramatic event — it tends to accumulate through a handful of well-documented pathways. Industrial sites that manufacture or use PFAS-containing products can release the chemicals into nearby soil and groundwater over time. Firefighting foam is another significant contributor: aqueous film-forming foams containing PFAS have historically been used for training exercises and emergency response at facilities such as airports and defence bases, and repeated use in these settings can allow the chemicals to seep into surrounding land and waterways.
Agricultural runoff can also play a role, particularly where biosolids or contaminated water have been used on farmland, allowing PFAS to migrate into local water systems. None of these pathways are unique to any single town or region — they reflect general, well-documented routes by which PFAS can move from industrial and commercial use into the broader water cycle.
What This Report Found
According to the 7NEWS report, researchers cited in the coverage found evidence connecting PFAS exposure to harm to fertility, prompting the recommendation that couples consider filtering their tap water as a precaution. The report frames this as an emerging concern worth taking seriously, rather than a settled matter — it's presented as research findings being brought to public attention, not as an exhaustive or final verdict on the health effects of PFAS.
We're summarising the report's claims here as they were presented, and we're not in a position to independently verify, endorse, or dispute the underlying research. Readers who want to understand the science in more depth should look at the original report and the studies it references.
How RO Filtration Reduces PFAS
Regardless of where you land on the broader research, PFAS in tap water is a legitimate water-quality concern, and reverse osmosis is one of the more effective filtration technologies for addressing it. Neeru's RO add-on (model USRO-3S1-2W), designed to pair with our whole-home filtration systems, is tested to reduce PFAS in filtered water. Full performance data, including the specific PFAS compounds tested and their reduction rates, is available in the RO system datasheet. To be clear about what this means: the system reduces PFAS levels in the water that passes through it. It is not a medical device, and it does not prevent, treat, or otherwise address fertility or any other health condition — it's a water treatment product, and its role is limited to improving the quality of the water coming out of your tap.
If you're weighing up whole-home filtration versus a point-of-use RO system, it helps to see how the two work together. See how the RO add-on works for a full breakdown of installation, capacity, and what it filters alongside our standard whole-home system.
For households concerned about PFAS specifically, adding RO filtration at the point where you draw drinking and cooking water is generally considered a practical, verifiable step — the datasheet gives you the actual reduction figures rather than a vague marketing claim, which is worth checking regardless of which system or brand you're considering.
