DESCRIPTION Keep your Lay-Z-Spa hot tub's water looking crystal clear with the Lay-Z-Spa Filter Cartridge. When your filter cartridge is no longer usable, a replacement cartridge helps to ensure your hot tubs water continues to be effectively filtered to leave your hot tub debris free. From leaves to bugs and other garden debris, these filter cartridges will continuously cleanse your water (when the filter pump is activated). With regular cleaning these hot tub cartridges can be reused multiple times by simply cleaning with warm soapy water. How do they work They work by catching dirt and grime when the water is pumped through them. As your pump will usually be continuously cleaning and filtering the water when it is turned on, this dirt can quickly build up, especially when the hot tub or pool is regularly used. To find out which filter cartridge is compatible with your pool or spa, please refer to your pump manual. Safety Warning Not suitable for children under 8 years old. For use under adult supervision.
