Why It Stands Out

This package groups the routinely replaced sediment and carbon filters for the PB-TLRO4H50T system into one set. Two sediment filters and two pre-carbon filters support more frequent replacement, while the included post-carbon filter handles the final filtration stage.

The model-specific configuration helps eliminate the need to locate each Stage 1, Stage 2, and Stage 4 filter separately.

Replacement & Maintenance

• Confirm that the installed system model is PB-TLRO4H50T before ordering.

• Shut off the water supply according to the system manual before replacing filters.

• Relieve system pressure before opening filter housings.

• Replace each filter in the correct stage and flow direction.

• Inspect housing O-rings and sealing surfaces before reassembly.

• Flush new filters according to the manufacturer’s instructions.

• Check all connections for leaks after restoring the water supply.

• Do not use filters that are cracked, damaged, contaminated, or incorrectly sized.

• Actual filter life depends on water quality, consumption, pressure, and operating conditions.

• Replace filters sooner if water flow, taste, odor, or system performance changes.

• Follow the system manual for separate reverse osmosis membrane replacement.
