Media cartridges are popular for a range of applications such as drinking water, window cleaning and aquatics. All of our Empty Refillable Filter Cartridges are supplied with an integrated gasket for a positive seal with the housing, and filter pads at either end to prevent media from migrating out of the cartridge. When the media inside is expended simply unscrew the cap, empty the cartridge and re-fill it. This can be done multiple times which minimises plastic waste.

We offer a range of water treatment resins and media which can be used in these empty cartridges. We also offer pre-filled media cartridges with your choice of de-ionising resin (standard and colour change), water softening resin, granular activated carbon and polyphosphate – these can be found under media filters category.

How Often Do I Need To Replace These Refillable Filter Cartridges?
These filters do not need to be replaced unless they are damaged, only the media or resin inside needs replacing when expended.

Key Product Information:

  • Eco-friendly alternative to single use media cartridges
  • Fill with your choice of water treatment media
  • Filter pads to prevent media migration
