    How often do u have to change the filter stage 5 systems?
    Question by: Wes Jennings on Apr 23, 2022, 7:32 AM
    Hey there,
    Thank you for reaching out to us. We recommend changing the filters every 6-9 months, the DI as it changes colors and the membranes about every 2-3 years.

    Please let me know if you need anything further and take care!
