Water Filter Replacement
Genuine iSpring replacement cartridges for every system we install.
Stocked locally in Rosarito — no waiting for shipments from the U.S. Filter lifespan depends on your water source, usage, and system type. As a general rule, whole-house carbon cartridges should be changed every 3–6 months in Baja due to higher sediment loads. RO membranes last 2–3 years.
