Stage 1 RO Prefilter – 5 Micron Sediment Cartridge

Give your reverse osmosis system a clean start with this standard 10-inch × 2.5-inch sediment prefilter. Used as the first filtration stage, the 5-micron option captures dirt, rust, silt and sand before water passes through the remaining RO filtration stages.

Compatibility

Suitable across RO brands where the system uses a matching standard 10-inch × 2.5-inch cartridge housing and specifies a 5-micron sediment prefilter. Check your existing cartridge dimensions and system manual before ordering.

This is not a universal fit for every RO system. Proprietary, encapsulated and quick-change systems may require their own replacement cartridge.

Choose the correct micron rating

This listing also offers a 1-micron variant. Select 5 Micron for the stage 1 application described here, unless your system manufacturer specifies a different rating.

Replacement and care

Replace and flush the cartridge according to your RO system manufacturer's instructions. Your replacement schedule will depend on water quality and usage.
