Great Start Pre-Filter Hose-End Spa Fill Filter
The Great Start Pre-Filter is a hose-end water filtration system designed specifically for hot tubs and spas. This innovative filter attaches directly to your garden hose and removes harmful metals, minerals, sediment, and debris before they ever enter your spa. By filtering your fill water at the source, you protect your spa's plumbing, jets, heater, and surfaces from scale buildup and staining.
Whether you're filling a new spa, refilling after draining, or topping off your water level, the Great Start Pre-Filter ensures you're starting with the cleanest water possible. It's compatible with all hot tub brands including Bullfrog Spas, Jacuzzi, Sundance, Hot Spring, and Caldera.
What Does It Filter Out?
The Great Start Pre-Filter targets the most common water contaminants that affect spa water quality:
- Heavy metals (iron, copper, manganese)
- Calcium and magnesium (hard water minerals)
- Sediment and rust particles
- Organic debris
- Chlorine and chloramines (depending on source water)
