Public Hot Tubs Require Pressurized Closed Filtration Systems. Shouldn’t Yours?

The hot tub or spa at your public pool, gym, hotel or rec center is required by law to have a pressurized closed filtration system, but the hot tub you purchase from a dealer won’t have one - unless you have a Coast Spa. Coast Spas is one of the only hot tub companies in the world to offer Pressurized Filtration on all their premium hot tubs. Our Patented Hydro Cyclonic Filtration System, is the only commercial-grade pressurized filtration system in the hot tub market that forces debris to evenly distribute over the filter cartridge in a cyclonic motion. This integrated design of Water Diversion Blades directs water into rotating circular flow pattern around the outside canister wall before being cleaned by the filter.

83% More Efficient. 20% Faster.

Coast spas and Pleatco, the filtration leader, teamed up to test the effectiveness of the Coast spas filtration system. In independent testing from a New York Laboratory, using 5 pounds of silica dust. It was found that the Coast Spas’ Hydro Cyclonic Filtration System was 83% more efficient and 20% faster at clearing this silica from the spa water then the leading competitive filtration system. The filtration process works faster and more efficient thereby reducing the strain on your pumps and equipment resulting in a lower cost to operate. Over time this equates to significant cost savings, thus presenting a smaller environmental footprint. These small steps Coast takes to build a better spa not only provide the ultimate in filtration but can even help reduce energy usage, ie. global warming benefits to boot... all via equipment that has superior performance.

Powerful for Jetted therapy. Intelligently Engineered for Max Energy Savings.

Coast Spas uses Xtreme Jet Pumps not only for their low failure rate and low cost to operate but because when mated to the proper plumbing and Jets, offer a truly effective massage. From the Monster Flow 7HP pump to the 1.5HP Smart Flow pump, all are designed to push the maximum pressure through to our specially designed Luxury Trillium Massage Jets. During the spa's filtration cycle, these same jet pumps are activated at one third the RPM, to pressurize the filtration system.

During the filtering cycle, Coast's Xtreme pumps will run on an ultra-low Amperage, using only 1.2Amps for our Yellow Super Flow Pumps. All Filtration cycles are fully programmable for duration and frequency. One more way Coast Spas is The Worlds Best Built Spa! During the programmed filtration time, your hot tub pumps will consume about as much power as your backyard aquarium pump yet turn over a much higher volume of water.

Debris and Contaminants naturally settle to the Floor of a Hot Tub. Coast Spas Developed the Sweeper Jet to help with cleaning this hard to reach space. Dirt, sand and other debris will find it's way into your hot tub, whether by feet, wind, trees or a structure above. Regardless of how it gets into your hot tub, you want it gone.

Coast's Self-Cleaning Sweeper Jet is activated during the filtration cycle and blasts the collected dirt, sand and other debris off the floor to be drawn into the filtration system.
