The Clean and Clear® Replacement Cartridge Element removes dirt, debris, and fine particles from the water as it flows from the pool and back through the return lines. By continuously filtering the water, the cartridge helps maintain water clarity, supports proper chemical balance, and reduces overall system wear. It can be conveniently rinsed clean in minutes with a garden hose. Filter cartridges do not require backwashing, which helps conserve water and reduce chemical loss.
