To maximize the life of your filter cartridge:

• Clean the elements as instructed

• Do not use a stiff brush to scrub the media

• Maintain your spa water's chemisty

• Alternate two sets of cartridges when ready to clean

• Use a type of enzyme treatment to break down oils

It's time to change your filter when:

• You notice shorter cycle times between cleanings

• You notice a lower water flow rate and higher differential pressure

• You notice a catastrophic failure such as a tear in the media or center core collapse

CHECK YOUR CURRENT FILTER LENGTH, DIAMETER, OPENING AND SIZE BEFORE ORDERING TO CONFIRM IT'S SPECIFICATIONS
