How effective do the filters have to be? Is there any type of effectiveness certification for the filter?
It is important to note that the law states that filters must protect against visual depictions outlawed by the legislation. The filter does not have to prevent access to all such depictions. (No filter is 100% effective in preventing all such access.) In developing the CIPA regulations, the FCC declined to further define the filter requirements or to adopt any type of definition or certification on how effective a filter must be, beyond the very general protect language of the law. Thus, there is no such thing as an FCC certified CIPA compliant filter.
