Water Clearer, Cleaner than the Competition
Coast Spas is the only residential spa manufacturer using a closed pressurized system, just like what you find in a large, commercial private or public pool. The patented technology of our Hydro Cyclonic Filtration System works inside a separate chamber where tornado-like action cleanses your water, locking debris and contaminants in the filter and chamber – for good, even when turned off.
Adding to this unique hygienic system, our filter cartridges come in sizes up to 175 square feet, the largest in the industry. Bigger is better, allowing improved water flow that puts less stress on your system while doing more work to ensure crystal clear waters for your enjoyment.
