High-density threaded cartridge filter for hot tubs and spas, designed to capture dirt, fine debris, oils and other contaminants before they reach the pump or heater. The dense filter media maintains strong water flow while trapping more particulates, helping reduce chemical usage and energy costs for cleaner, healthier soak sessions. Easy maintenance—twist off the old cartridge and twist on a replacement to restore filtration performance immediately.

Twist off the old, dirty filter and twist on a fresh one to immediately restore your spa's filtration power. Ensure the filter is securely screwed in for a tight fit. Compatible with most Wave Spa models (2020 onwards) with integrated heaters and many other hot tub brands; please confirm your model’s requirement before purchase.
