Recent testing by Pleatco Labs comparing Coast Spas' Hydro Cyclonic Filtration System against skim filtration systems has shown that the Coast Spas system filtered significantly faster and more efficiently, according to the company.

Pleatco measured the amount of media introduced into both spas featuring the different filtration methods, and recorded the length of time required by both systems to filter the media. Pleatco has published an official detailed report on its findings.

The Hydro Cyclonic system used in the tests was a stock system identical to that included on any spa sold worldwide by the Coast Spas dealer network.
