75 sq ft Replacement Filter for Dimension One Spas - Butterfly Twist Lock - 7-1/8" x 10-1/2"

Replacement cartridge filter engineered for Dimension One and At Home Hot Tubs manufactured after 2000. This 75 square foot filtration cartridge measures 10-1/2" in length by 7-1/8" in diameter and utilizes 3oz filter media for optimal water clarity.

The cartridge features a castle-style closed top with integrated tabs and an innovative butterfly-style twist lock base. Installation is simple: align the cartridge over the butterfly-shaped opening in your filter housing, slide down, and rotate to secure in place. The 2" open bottom with twist lock mechanism ensures a watertight seal.

Important Note: A separate butterfly-style holder that snaps into the filter housing base is required to secure this cartridge. This holder component is sold separately if your spa system needs replacement.
