We do not stock the E5315 filter. Email firstname.lastname@example.org
or call 1-888-801-7873 if you would like to special order the E5315. An alternative option is the E5615
filter below. This is a 12" version of the E5315 filter which means it will last longer. The E5615 has the same contaminant reduction as the E5315. If you need a 6" filter, the E5320
filter below is stocked and has slightly different contaminant reduction. Both of these alternatives will fit in the filter head used by the E5315.
