We do not stock the E5428 filter. Email email@example.com
or call 1-888-801-7873 if you would like to special order the E5428. An alternative option is the E5628
filter below. This is a 12" version of the E5428 filter which means it will last longer. The E5628 has the same contaminant reduction as the E5428. If you need a shorter filter, the 6" E5320
filter below is stocked and has additional contaminant reduction. Both of these alternatives will fit in the filter head used by the E5428.
