Because a filter is designed to collect unwanted particles, debris, oils, soaps, etc, it will need to be cleaned periodically. A blocked cartridge can put undue pressure on your pump and motor and decrease the life of these parts. The Cover Guy Scumball freely floats and removes lotion, body oils and sunscreen from the water before they block up your filter! Grab yours HERE.

All The Cover Guy products are brought to you with quality, safety, and value in mind as part of our commitment to customer satisfaction. We use high quality raw materials and the most up-to-date manufacturing machinery and processes to ensure that we’re providing the highest quality filter cartridges to the market. We have you covered for your Filbur, Pleatco, or Unicel hot tub spa replacement filter needs.
