On city water, get a housing, fittings, and one of these https://www.amazon.com/MatriKX-Technologies-36-250-10-MATRIKX-ChloraGuard-Chloramine/dp/B08PXP1HJ5 I run them 18 months but I'm extreme in my cleaning and sanitizing when servicing. There's been zero degredation based on any indication or test that I have access to. Regular filters would gag a maggot when I changed them at recommended intervals.
