Clarathon Premium Ultra Filters: the most effective, durable pool & hot tub spa filter cartridges. These blue media filters feature Antimicrobial protection which lasts for the life of the cartridge, & inhibits the growth of bacteria that can foul and weaken a cartridge.
Antimicrobial filters are easier to clean and less prone to odors & staining than ordinary filters. When changing spa water, always rotate the soiled ones out with clean, dry spares. The result is longer filter life and no waiting.
Product notes: Money-saving reusable Microban Antimicrobial replacement for Master Spas Eco Pur mineral inner filter. Use with a conventional or mineral spa sanitizer system. Antimicrobial media protects the filter cartridge, and is not a water sanitizer. Verify correct spa filter dimensions by measuring old filter. Measurements may vary from specifications by about 1/8" or more due to expansion, shrinkage, or manufacturer's variances. 2 pack of filter cartridges.
