The Best Spa Filtration System on the Planet



Concerned about the cleanliness of your spa?

If you’ve been in hot tub recently, you’ve likely experienced a “skim filtration system” where the filter shares the same spa water as you. When the jets are turned off, you can watch the dirt and grime float back into the spa water. Eeeew!

To keep your spa water clean and free of debris and bacteria, we recommend Coast Spas, which feature an exclusive, commercial-grade Hydro Cyclonic Filtration® System.

Skim Filtration vs. Hydro Cyclonic Filtration

With Coast Spas’ Hydro Cyclonic Filtration System, the filter is removed from the bathing area. This means that any dirt, oils, perfumes, or contaminants can’t re-enter the spa water that you soak in.

The pressurized sealed canister helps keep the water crystal clear and clean, which is vital for your family’s health and safety.

The patented pressurized filtration system uses a centrifugal hydrodynamic flow to evenly distribute debris over the filter media. This improves the flow rate of water to vital equipment and maximizes the longevity of each filter cartridge. This flow allows for the whole 175 square feet of filter to be utilized efficiently, for a thorough cleaning of the water before it returns back into the tub area.

Independent Testing

A series of tests performed by an independent laboratory compared a skim filtration system to Coast Spas’ Hydro Cyclonic Filtration System. They dumped 5 pounds of silica sand into both spas. The Hydro Cyclonic Filtration System cleaned it out in three hours, while the skim filtration system took over 18 hours and had a 20% reduced flow rate for it.
