Our RO/DI replacement filter kit includes standard-sized sediment, carbon, and DI filter cartridges that fit most RO/DI systems such as Marine Depot KleanWater, SpectraPure, AquaFX, Seachem, Kent Marine and many more.

In most situations, RO/DI cartridges need to be changed out every 6 months or so to ensure the water produced does not have impurities that may harm aquarium inhabitants.

The dual density sediment filter provides consistent performance while the ½ micron carbon block filter will help extend the life of your TFC membrane.

The Mixed Bed DI filter used non-recycled nuclear-grade resin that maximizes performance and last longer.

Replace your cartridges with the affordable Marine Depot RO/DI Replacement Filter Kit to ensure the highest quality of water produced by your RO/Di System.
