Filtration systems and circulation

Simplicity® Filtration System

The innovative Simplicity® Filtration System, utilized in the M Series™  , A Series™  , and Swim Series™  lines, simplifies your spa experience with its revolutionary flat filter design. Simplicity captures debris more efficiently than traditional filters by spreading flow evenly across its entire surface, resulting in amazing water-cleansing performance from a smaller filter area. In addition, Simplicity’s space-saving design creates room for extra seating and filters cost less than bulky traditional filters. Simplicity combines superior performance with practical design for a smarter spa filtration solution.

WellSpring® Filtration

The STIL™  and X Series™  lines feature WellSpring filtration, a highly effective dual filter system with a cage-free filter design that helps you maintain clear water at all times, while using less plastic than other traditional cylinder filters. WellSpring® filters are easy to access and simple to remove for periodic cleaning. 

Wellspring™ Dedicated Filtration Pump

The dedicated Wellspring filtration pump is a quiet, vibration free, circulation pump that is more than eight times as effective at moving water through filters compared to other circulation pumps. Your spa will filter better, and quieter, while consuming up to 60% less operating energy, saving you money over time.

EOS™ O3
Enhanced Ozone System

EOS™  O3 is an advanced water purification system that eliminates impurities using the powerful oxidation properties of O3 gas. This unique three-part system generates up to three times more ozone than standard systems, combines O3 with spa water in a high-contact mixing chamber, and then filters out over 99% of excess ozone gas to prevent any negative effects. It operates automatically as your spa filters for hands-free water conditioning that supports your sanitizer in keeping water clean, clear, and safe. 

WellSpring™ Ozone System

The WellSpring™ Ozone System  creates ozone (O3) gas, which increases the purifying oxidation potential of your spa’s own water. Keep your spa clean and significantly reduce the amount of sanitizing chemicals needed.

Read how an easy spa experience can help you achieve a more peaceful life.

5/5
"This is by far the easiest spa to maintain that we’ve owned. The cartridges and filter setup was an awesome idea. No more guessing needed. And those jet packs?! Love them."
Mark E.
5/5
"I had a spa with a salt system for 5 years. I hated it. The water never balanced and it was very difficult to maintain contrary to the claim of its ease. I "traded" it for a Bullfrog Spa. I couldn't be happier. We have used it more in 6 months than we did with the other tub in 6 years. I highly recommend."
Scott B.
5/5
"The spa is beautifully designed, super comfortable to sit in, well functioning massage jets and above all super-easy to maintain. The @ease cartridges and maintenance settings allow for keeping the water quality very high with minimum effort."

Frequently asked questions about water care

The best hot tub water care system is one that best helps you keep your water clear, clean, and safe. This usually means good filtration, balanced water (pH and alkalinity), water free from contaminants, and safe levels of chemicals without irritants. In our experience, the best systems to achieve these goals integrate three essential components: the filtration system, a low-chem primary sanitizing system, and an effective secondary oxidization system. Together, these systems, in 3 stages, ensure that your hot tub water remains clear, free from contaminants, and safe for you and your loved ones, while providing the easiest maintenance process possible.

Hot tub filtration systems remove debris, contaminants, and impurities from the water. Water circulates from the spa’s main body and passes through filter membranes that trap particles such as dirt and organic matter. This process is facilitated by a pump that ensures continuous water circulation that cleans all of the spa’s water several times in a day, resulting in clear and safe water for users.

The Simplicity Filtration System is a patent-pending, user-friendly, and affordable spa filtration system designed by Bullfrog Spas. Simplicity Filtration is available in our premium spa lines and is a key part of the Simplicity Total Water Care approach to maintaining clean, clear, and safe spa water. The Simplicity system features a unique flat filter that does not require a plastic frame. Simplicity Filters are easy to remove and clean. This system also features a high-quality corrosion-resistant filtration pump in most models, which ensures consistent water flow, quiet operation, and reliable performance over time.

Sanitizing systems kill bacteria and other pathogens in the water. The two most common sanitizers are chlorine and bromine. Chlorine is fast-acting, while bromine is considered more stable in high temperatures. Both ensure water safety by disinfecting the hot tub. Spa water care systems often known simply as “salt systems” actually generate either chlorine or bromine from that salt in order to sanitize the water.

FROG @ease is a two-part, low-touch sanitizing system, with cartridge formats created specifically for use in Bullfrog Spas® brand hot tubs. FROG @ease uses a mineral cartridge to inhibit bacteria growth and a low-dose SmartChlor® cartridge for additional sanitation. This system creates fresh mineral water, which feels great on the skin, while greatly reducing the amount of chlorine necessary to keep the water clean over a extended periods. SmartChlor cartridges often last around a month between changes, sometimes more, depending on spa size and usage.

Water care approaches known as “saltwater” or “salt” systems use an electrical process to generate either chlorine or bromine, often in generous amounts, from a salt added to spa water. The production of either chemical, whether chlorine or bromine, is great for sanitization of spa water, however, these systems can come with some drawbacks. Although often billed as automated systems, salt systems are not maintenance-free. These systems often require regular cartridge replacements, probe or cell cleaning, along with frequent checks for effectiveness, water balance, and to keep over-production or under-production of chlorine or bromine in check. A high volume of salt in spa water can cause hard water stains and can corrode or otherwise damage hot tub components over time. Due to our commitment to our customers to provide durable spas that will operate reliably for years, Bullfrog Spas does not currently offer salt-based chlorine or salt-based bromine systems.

Oxidation systems introduce active oxidizing molecules to spa water to eliminate both organic and inorganic contaminants, clarifying the water in the process. These systems complement primary sanitizers, often reducing the amount needed, providing a gentler and eco-friendlier approach to maintaining water clarity. Common oxidation methods include Ozone systems, UV systems, and AOP systems.

AOP (Advanced Oxidation Process) systems use atomic oxygen (O1) to create hydroxyl radicals, which break down contaminants through powerful oxidation. Bullfrog Spas’ Premium AOP System by Clear Comfort® offers powerful oxidation effect that allows for minimal chemical use, while creating fresh, clean, clear water, and a low-maintenance approach. Customers enjoy a safe, clean, clear water and a worry-free spa ownership experience.

UV systems use UV-C lamps to emit ultraviolet rays into passing water. These rays disrupt the DNA of microorganisms, rendering them harmless. This technology enhances water quality and supports primary sanitizers. UV bulbs must be maintained and change to ensure effectiveness.

Ozone systems use ozone (O3) gas to eliminate bacteria and contaminants through oxidation. Bullfrog Spas offers two ozone systems: the Wellspring Ozone System and the EOS Enhanced O3) system, both of which operate automatically to support chemical sanitizers and promote healthier water.

Bullfrog Spas offers a variety of water care systems including the best-in-class 3-part Simplicity Total Water Care system, which is a combination of filtration, sanitizer, and oxidation. Stand alone systems used in Simplicity Total Water Care, or on their own include Premium AOP by Clear Comfort, EOS Enhanced O3, Wellspring O3 system, and FROG @ease for Bullfrog Spas (in both Simplicity and Classic formats). These systems offer options for safe, eco-friendly water care, with low-touch ease and reduced chemical use.
