Methodology
Annual filter costs use manufacturer-published OEM replacement cartridge prices at current MSRP. Third-party cartridges typically cost 30–60% less. Cost-per-gallon estimates use your household size and daily usage input. All prices in USD; updated quarterly. For whole-house systems, professional installation cost (typically $150–$400) is not included.
