Frequently Asked Questions
What filter cartridge does the Bullfrog A-Series (2018+) use?
The Bullfrog A-Series (2018+) (2018-present) runs the PBF40 (also sold as FC-9900, the same physical cartridge with a different sticker). Confirm by reading the label inside the filter compartment or the part number printed on the end cap of your existing cartridge before you order.
How many filters does the Bullfrog A-Series (2018+) need?
2 cartridges. Replace all of them at once. Put a fresh cartridge in next to a worn one and the new one carries more than its share and burns out faster than it should. Pop open the filter housing and count what's installed before you order, just to confirm the number for your serial.
How often should I replace the filter on my Bullfrog A-Series (2018+)?
Most Bullfrog owners get 12 to 24 months out of a cartridge, depending on how heavily the spa is used. A larger tub like this holds more water, so the cartridge works a little harder and tends to want cleaning more often. Rinse it monthly with a hose, hitting the pleats at about a 45-degree angle. Soak it overnight in filter cleaner every three to four months. Replace it when the pleats are torn, the seams are stained brown and won't come clean, or a soak no longer drops the post-rinse pressure.
