A system for filtering water in a spa that provides safety and greater filtration. The system may include a filter secured to a core. The core may include first and second cages with a plurality of openings allowing water to freely pass through the filter and core while preventing larger objects from passing through. The first cage may provide an orientation feature to position the filter in one direction. The second cage may hold mineral cartridges. The core may be secured to a fitting that is secured to the suction line of a spa via a ratchet like engagement feature. The fitting and core prevent back out of the core unless manually overriding the arm on the core which engages fins on the fitting. The filter may be removed and replaced while the core remains in place providing safety to the user. A cap secures the whole assembly into place.
