We’ve been building spas for a long time now and we know just how important it is to have clean water in your hot tub. For maximum enjoyment, peace-of-mind for you and your family and the longevity of your equipment nothing is more crucial than the condition of your spa water. For this reason Coast Spas installs a commercial-grade pressurized filtration system in every spa. However, filtration is only one of two important systems that treat your hot tubs water. Purification systems actively attack unwanted contaminants in your spa water that are unable to be captured by a filter. The most common purification system on hot tub has always been an ozone generator but advancements in UV sterilizers and salt-water generators are now growing in popularity due to their rise in effectiveness. Your purification upgrades work in harmony with your Hydro Cyclonic Filtration System®. Hydro Cyclonic filtration is proven to be a far superior method of filtration and one of the only pressurized commercial-grade filtration systems available. The combination gives bathers the highest level of pristine, clear water.
