How frequently filters need to be replaced


Hello Jani, Thank you for reaching out. For the RO-90 system, the pre-filters (Stages 1–3) are typically replaced every 12 months, while the RO membrane and Stage 5 filter are replaced every 3–5 years, depending on water quality and usage. Please let us know if you have any other questions—we’re happy to help. Best regards, Aisle A. APEC Customer Service
