The Tier1 RS-23-SED5 is a 5-micron sediment pre-filter specifically engineered for reverse osmosis systems. This 5-micron rating allows it to effectively capture dirt, sand, rust, silt, and other suspended particles before they reach the RO membrane. By trapping these sediments early, the RS-23-SED5 helps extend the life of downstream carbon filters and the sensitive RO membrane, ensuring optimal performance of your Tier1 reverse osmosis system.

The Tier1 RS-23-SED5 Reverse Osmosis Pre-Filter should be replaced every 6 months or sooner depending on your incoming water quality and usage. If your source water contains high levels of sediment or turbidity, you may need to replace it every 3–4 months. Regular replacement is critical in a Tier1 RO system, as a clogged sediment pre-filter restricts water flow and forces the downstream carbon block and RO membrane to work harder, shortening their service life.

The RS-23-SED5 is a standard 2.5" x 10" filter designed to fit most Tier1 reverse osmosis systems as well as virtually any standard-size 10-inch RO housing. It is an ideal first-stage (Stage 1) sediment pre-filter for multi-stage RO setups. Always confirm your housing dimensions before ordering to ensure a proper fit with your specific Tier1 RO unit or comparable standard-size system.

The Tier1 RS-23-SED5 is specifically designed to reduce sediment-based contaminants including sand, silt, dirt, rust flakes, scale particles, and other visible suspended solids down to 5 microns in size. It is not intended to remove chlorine, chemicals, or dissolved contaminants — those are addressed by the carbon and RO membrane stages of your system. Its primary role is mechanical filtration to protect the subsequent stages of your Tier1 RO system.

Yes. After installing your new Tier1 RS-23-SED5 sediment pre-filter, you should flush the system by running water through it for several minutes (or drain the first full RO tank) to clear out any loose fibers or manufacturing residue. Once flushed, the RS-23-SED5 will deliver consistent sediment reduction and help your Tier1 reverse osmosis system produce clean, high-quality filtered water at peak efficiency.
