The Intex S1 replacement cartridge filter is designed for selected models of inflatable hot tubs and their pumps. The filter cartridge, made from higher-quality, thicker paper with a greater number of pleats, effectively captures small impurities from the water and contributes to cleaner hot tub operation.
To maintain good filtration performance, we recommend checking and cleaning the cartridge regularly with a stream of water, for example using a garden hose. Replace the filter with a new one when it is significantly dirty or worn. Installing the filter in the pump is easy; follow the manufacturer's instructions.
