The Filbur FC-1009 is a spa filter cartridge that replaces cartridges for the Master Spa Eco-Pure (Stage 2) Disposable 2007 and 2008 model spas. Filbur cartridges are tightly pleated and made of a durable polyester material and wide support bands for long-lasting quality. The FC-1009 filter cartridges reduce the growth and spread of harmful bacteria and other microorganisms and promote a healthy and safe spa water environment when they are properly cleaned and maintained, as well as when they are used in conjunction with proper filtration times and balanced water chemistry.
