Great Barrier H2Hose Pre-Filter for Hot Tubs & Pools

The Great Barrier H2Hose by Essentials (#5038) is a pre-filter that screws onto your garden hose. Use it when you fill your hot tub, swim spa, pool or fountain. It removes metals and other contaminants from tap water before they reach your spa, which helps prevent staining and scale and reduces the chemicals needed right after a fill.

Filter capacity: 25,000 gallons.
