Filter Revive is a fast acting filter cleaner, working in less than 1 hour. Traditional filter cleaners require harsher formulations and significantly more soak time to do their job. The unique formulation allows filter cleaning to be done in a fraction of the time, making this a much easier job to perform regularly. Formulated with Hydrogen Peroxide and powerful cleansers and degreasers, for a cleaner, whiter finish. A cleaner cartridge filters better while requiring less frequent rinsing. Clearer water and less work. A perfect combination.
