At Modern Castle we assess water filters using a 3rd party laboratory. Our scoring methodology is primarily based on objective data from the laboratory. We use this data alongside a battery of tests and assessments to determine the best water filters.
You can see a complete list of all water filter reviews we’ve tested to date, along with the report from the laboratory.
