Replacement Filter Sets – we recommend changing your bottom filters (sediment, carbon block, DI) every 6 months. Or, filter life can be more accurately monitored with a TDS Meter and pressure gauge. The filters sets are conveniently packages to let you pick out exactly what you need for your AquaFX RO or RO/DI System. Our filter sets also fit most other brands or RO and RO/DI systems.
