Pack of 2 mineral filter sticks, for spas and hot tubs, chlorine/bromine reduction, universal, up to 2000 L, lasts 4 to 6 months

These two mineral filter sticks are designed to optimize water quality in home spas, hot tubs, and jacuzzis. They work by selectively adsorbing heavy metals, phosphates, and organic residues, while gradually releasing beneficial trace elements. Made from certified ABS material, they meet European health and safety standards for private water treatment equipment. Compatible with conventional filtration systems (cartridge, sand, diatomaceous earth), they require no special adjustments or maintenance. Each stick is calibrated for a maximum volume of 2000 L, which corresponds to most standard residential spas. Their effectiveness is maintained for a continuous period of 4 to 6 months, depending on actual usage conditions (average temperature of 34–38 °C, frequency of weekly use, and number of bathers). The package contains only the two yellow sticks—no additional accessories are included.
