Regularly replacing your hot tub filter is an essential part of maintaining your spa and extending its lifespan. Hot Spring Tri-X filters manage the water that enters your hot tub and filters out debris, dirt, and other items, preventing them from entering the pipes and causing damage or build-up in the pump or inner workings of your hot tub.
