A stainless steel re-packable filter tube for "MAKO" style filter chambers. Rugged and well made to withstand many refills. This re-packable system replaces the popular tall MAKO style cartridges such as PD-1803 (AIM-247) and PD-1503 (AIM-677).

With this system users can now pack their own filters with bulk purchased media. This system ships with internal spring, spacer and filter pads.
