Generally, a sediment filter needs replacement every 3 to 6 months, a carbon filter every 6 to 12 months, an RO membrane every 12 to 24 months, and a UF filter approximately every 12 months. Lifespans can vary based on water quality and type, so always prioritize the manufacturer's manual and instructions.
Key signs include a change in the water's taste or smell (such as salty, metallic, or muddy), a slower water flow when filling containers, and slight cloudiness or small particles in the water. An increase in TDS levels or receiving a filter replacement alert from modern indicators also signals the need for inspection.
After replacing the filter, you must flush the system according to the manufacturer's instructions and thoroughly check all connections for any leaks.
