Many of you are uncertain as to how often you should be cleaning and changing your hot tub filters. To be honest, most hot tub filters should be changed approximately every two years or so. As far as cleaning many manufacturers suggest you rinse your filter once a week. If you rinse it every month and clean it every three months when you do your fresh fill this would prolong your filter. This is an average and one that I`m hopeful you can find the time to do.
Also having a spare filter that you can alternate is suggested to allow your filter to dry completely before reusing.
Happy Hot Tubbing!
