Pentair Carbon Pre-Filter Replacement

In stock

This Activated Carbon Block Cartridge Filter is the original equipment stage one replacement for all GE Merlin Systems.

The GE Merlin-3038333 carbon pre-filter reduces chlorine and sediment to prevent fouling of the reverse osmosis membrane. This filter uses a modified carbon block with fibredyne technology to provide 3 times the sediment reduction of a traditional filter. Replace this filter every 6 months or after 10,000 gallons of use (whichever comes first) to extend the life of the reverse osmosis membrane.

This filter will remove chlorine and sediment down to 5-microns to protect the membranes. If your water supply contains unusual amounts of sediment and/or chlorine, or you find that you need to change this filter too frequently, it is recommended that you install additional, larger scale, prefiltration prior to the Merlin System.

For general sanitary reasons, and to keep your Merlin running efficiently, this filter should be changed at least every 6 months.

  • Advanced fibredyne technology provides 3 times the holding capacity of a standard carbon block filter
  • Reduces chlorine and sediment to protect the membrane from fouling for up to 10,000 gallons of use
  • Only one pre-filter is needed per Merlin system
  • For well water systems you can use the Merlin 1266690 sediment-only pre-filter
