Pure. Clear. Easy.

Bullfrog Spas’ Wellspring™ efficient water purification system is designed to help you maintain crystal clear water in your hot tub without the worries. Bullfrog Spas’ dual filter system guarantees maximum filtration. WellSpring filters’ Microban® technology is designed to assist with the elimination of unwanted contaminants without impeding flow. Filters are easy to access for periodic cleaning. Along with the proper sanitization agents, the Wellspring hot tub filtration system filters and purifies your spa water so you can relax worry-free.



100% water circulation guaranteed…

100% of the water in a Bullfrog Spa goes through the dual filter WellSpring Filtration System in each filtration cycle, including the water behind each JetPak. This attention to detail in water purification ensures that all areas of your Bullfrog Spas stay fresh and clean.

Additionally, this efficient hydraulic technology turns over (cleans) your spa’s water more than 10 times as frequently as the industry standard and uses less energy in the process.





More power, less energy, less noise…

This quiet and vibration-free circulation pump is more than 8 times as effective at filtering spa water than standard circulation pumps. This pump moves 35 gallons per minute to push every ounce of water through the dual filters many times per day.

The WellSpring Filtration Pump keeps your water clean in significantly fewer operating hours than standard pumps. This leads to an average savings of 60% in filtration energy costs (6,060 gallons per kilowatt vs. 3,480 gallons per kilowatt). Because the pump is larger, it will also operate cooler and more efficiently.




Your spa, your perfect temperature…

The WellSpring Heater in your Bullfrog Spa heats the water quickly and only when necessary. The patented M7 temperature and flow sensor technology increases consistency and performance. The ultra-efficient and dependable WellSpring Heater System reliably heats your hot tub water without any effort or worry on your part.





Reduce your chemical use…

The optional WellSpring High-Output Ozone Purifier and the EOS Enhanced O3™ System both greatly reduce the amount of sanitizing chemicals needed to maintain sparkling clean and fresh spa water. 

Ozone is one of the strongest water purifiers in the world. The WellSpring High-Output Ozone Purifier uses Corona Discharge Electrode Technology to consistently help clean your spa and minimize maintenance efforts.

The EOS Enhanced O3™ System can generate twice as much ozone as standard systems to more effectively charge spa water with free ozone, sanitize spa water, and destruct nearly all residual O3 gas. EOS has been third-party validated to kill 99.9% of the microorganisms that could be found in spas.
