The ORCA Cold Plunge hose filter connects directly to your standard garden hose. This carbon pre-filter is designed to filter your water before it goes into your cold plunge tub. Ideal for removing excess minerals, reducing chlorine, lead, and heavy metals from your tap water. The ORCA garden hose filter will also extend the life of your 10" pleated water filter by removing impurities that can prematurely clog the water chiller filter. Fill your cold plunge with clean, crystal clear water each and every time with the ORCA hose filter.
