How much does a whole house water filter installation cost?

Whole-house water filter installation cost varies by system type and your home’s plumbing, and Brothers Plumbing, Heating, and Electric confirms final pricing after an in-home assessment. The biggest cost driver is the system itself—single-stage carbon, multi-stage with UV, or a filtration-and-softener combo like our H2O Harmony options. We install, maintain, and repair whole-home systems and tailor solutions based on a quick water quality test before recommending equipment. Our licensed plumbers frequently install these systems in homes around Lakewood. After the core assessment, available savings may include $300 OFF a Silver Whole Home Water Filtration install.

What most affects price:

  • Pipe modifications, shutoff/bypass valving, and placement access
  • Required flow rate and filter size for your household
  • Pre-treatment needs (sediment, hardness) or choosing a filtration-and-softener combo
  • Post-install testing and setting up a maintenance plan

Schedule a water test so we can size the system correctly and provide a firm written quote.
