Microplastics Action Plan publishes general information about microplastics in drinking water, about water testing, and about water filtration. It is for informational purposes only. It is not medical advice and it is not a substitute for diagnosis, screening, or treatment by a qualified healthcare professional. On the state of the evidence we follow WHO, which reviewed the research on microplastics in drinking water and concluded that, based on the limited information available, they do not appear to pose a health risk at current levels, while calling for more research because the data on the smallest particles is extremely limited. We do not claim that microplastics cause any specific illness, and we do not claim that filtering them prevents or treats one. If you have questions about your own health, or about an exposure you think may have affected it, raise them with your doctor rather than with a product review.
We are not a certified water testing laboratory and we are not a water treatment contractor; nothing here is a laboratory result or a treatment system design. There is no single standardised method for measuring microplastics in water, so results from different test kits and laboratories are not directly comparable, and a reading from one is not a diagnosis. Test results, and any decision to install or modify filtration equipment, should be confirmed with a certified laboratory and a qualified water treatment professional, and checked against your state or local drinking water program, whose requirements differ by location.
