This premium replacement filter cartridge is designed for compatibility with select newer Cal Spa and Marquis Spas models. Featuring a 50 sq ft filtration area, this cartridge measures 12-1/2" in length and 5-3/16" in diameter. The bottom connection features 2" Male Pipe Thread (MPT) with thick threading and an outside diameter of approximately 2-3/8" (measuring between 2-1/4" and 2-3/8" edge to edge). A convenient integrated handle on the top makes installation and removal simple and efficient.
Important Note: While factory Cal Spa filters typically come in red, this white replacement cartridge functions as a perfect substitute and delivers equivalent performance.
