Under ideal circumstances, the bio-sand filter can produce drinking water of excellent quality which is safe to drink without further treatment. However, performance is user dependent and optimal performance can not be guaranteed. Therefore, BioSandFilter.org and the author(s) shall not be liable to anyone whatsoever for any damage resulting from reliance on any information contained on this website. This also applies to the consumption of water produced by a bio-sand filter. It should specifically be noted that, as with most other filters, a bio-sand filter can not always be relied upon to remove chemical contamination. A proper analysis of source water is therefore recommended.
