Where information was available and published, this information was used. Where information was not available, information was calculated, such as in F and G above, using the available published information. Where published information on systems was in conflict with the published information by the manufacturer, such as in C, D, and E above, items are highlighted in orange.
Data is based on manufacturer's life expectancy claims rather than the claims of the manufacturer's customer. Information collected from websites, corporate literature, internal testing and outside independent sources is believed to be accurate at time of publication. Neither this chart nor it's producer assume any liability, implied, expressed or assumed.
There are other gravity fed filter systems that claim they are not to be used with microbiologically unsafe or questionable water. We chose not to include those systems in this comparison chart.
