LeisureConcepts PTL18 Vita Duet Filter Element

This filter is specifically engineered for the Vita Duet spa model. While it features a standard 1.5-inch female threaded connection, it is designed with the specific dimensions and flow requirements of the Duet in mind, so we recommend sticking to the manufacturer's compatibility list to ensure a proper seal and filtration performance.

You should generally replace your filter element every 3 to 6 months, depending on usage. If you notice a decrease in water flow, visible debris accumulation that doesn't wash away, or if the filter media appears discolored or frayed, it is time for a replacement.

The PTL18 filter measures 8 inches in height and 4.5 inches in diameter. These dimensions are critical for the oval-shaped housing of the Vita Duet, so ensure your current filter matches these specs before purchasing.

No tools are required. Because it uses a 1.5-inch female threaded connection, you can simply unscrew the old filter and hand-tighten the new one into place. Be careful not to overtighten, as this can crack the plastic housing.

You can extend the life of your filter by rinsing it monthly with a garden hose to remove loose debris. However, even with regular rinsing, the filter media will eventually degrade and lose its ability to trap fine particles, making periodic replacement necessary for maintaining water clarity.
