We do not stock the E5321-P filter. Email email@example.com
or call 1-888-801-7873 if you would like to special order the E5321-P. An alternative option is the E5515-P
filter below. This is a 10" filter which means it will last longer. The E5515-P has the much more contaminant reduction than the E5321-P. 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 E5321-P.
