describe 1. Keep your Lay-Z-Spa hot tub water looking crystal clear with a Lay-Z-Spa filter. When your filter is no longer functional, replacing the filter helps ensure that your hot tub's water continues to filter effectively enough to keep your hot tub free of debris. From leaves to bugs and other garden debris, these filters will continuously purify your water (when the filter pump is on). 2. These hot tub filters can be reused many times with regular cleaning, simply washing with warm soapy water. 3. How do they work? As water passes through them, they trap dirt and grime. Since your pump is typically constantly cleaning and filtering water when it's on, dirt can build up quickly, especially if your hot tub/pool is used regularly. To find out which filter is compatible with your pool or spa, refer to your pump manual. Safety Warning: Not suitable for children under 8 years of age. Please use under adult supervision. Packing list: 10 filter elements
