We do not stock the Q5340 filter. Email email@example.com
or call 1-888-801-7873 if you would like to special order the Q5340. An alternative option is the Q5640 filter below. The Q5640 is a 12" version of the Q5340 filter. The Q5640 has the same contaminant reduction as the Q5340. If you need a 6" filter, the Q5386 filter below is stocked and has additional contaminant reduction. The Q5386 carbon is GAC and not coconut carbon like the Q5340. All of these alternatives will fit in the filter head used by the Q5340.
