Great Start Pre-Filter Hose-End Spa Fill Filter

The Great Start Pre-Filter is a specialized hose-end spa fill filter designed to remove harmful metals, minerals, sediment, and debris from your source water before it enters your hot tub. This innovative filtration system connects directly to your garden hose, providing professional-grade water treatment during initial fills, refills, and top-offs. Unlike standard garden hose filters, the Great Start Pre-Filter uses advanced filtration media specifically formulated for spa water chemistry. It captures iron, copper, calcium, and other minerals that cause staining, scaling, and equipment damage—problems that are much harder (and more expensive) to fix after the water is already in your spa.
