We have experienced that smaller ceramic filters are the preferred method under different circumstances. A big bio-sand filter usually belongs to everybody, hence nobody, and the maintenance of the filter will be inadequate. Placing the filter on the property of a single household creates other problems as the owner of the land will occasionally start charging his neighbors to use the filter.

We have recently opted to use the bio-sand filter for schools or organizational settings, whereas we will be using the smaller ceramic filters for household use.
