Genuine OEM filter cartridges for whole house, under-sink, RO, and shower filtration systems. Replace on schedule to maintain performance and warranty coverage.
Regular cartridge replacement is the single most important maintenance task for any water filtration system. A saturated cartridge not only stops filtering effectively — it can harbor bacteria, release previously captured contaminants, and damage downstream components including RO membranes.
General guidelines: sediment pre-filters every 3–6 months, carbon block and GAC cartridges every 6–12 months, specialty cartridges (fluoride, arsenic, nitrate) every 6 months or per your water test results. Not sure which cartridge your system uses? Contact us with your model number.
