What kind of filtration is best?
Filters in a skimmer, as the name says, only skim the top of the water, leaving the heavier debris to sink to the bottom unfiltered. Coast’s Cyclonic Filtration System™ incorporates angled blades to drive water into a filter canister in a cyclonic action, moving more water through the filter with less restriction and allowing the motor to work more efficiently and run cooler. Our Cyclonic Filtration System further uses the powerful main pumps as low-speed circulation pumps to reduce the number of components and wear-and-tear, helping to make our system one of the most energy efficient in the spa industry. Coast/NorthWind filters range from 50 square feet up to an industry-leading 175 square feet. Significantly improving water quality is our Corona Discharge Ozonation System, which extracts ozone from the air and injects it into the water.
