    How to Choose: Parts Buyer's Guide

    Buy parts that fit your model

    Cartridges are sized to specific housings. Match the part number to your exact system, or use a verified universal size (10" standard vs. 20" big-blue) before ordering.

    Follow the replacement schedule

    Replacement intervals vary by part, model, and conditions. Consult current product documentation.

    Genuine vs. compatible

    OEM and compatible parts may differ. Confirm compatibility and review current model requirements before ordering.
