How much does a whole house water filtration system installation cost?
We do not post flat pricing for whole‑house water filtration. Your cost is confirmed after an in‑home evaluation of your plumbing, water quality, and system options. We install whole‑house systems and support them with annual filter maintenance and service.
Quick prep before your estimate:
- List your goals (taste, scale, sediment).
- Note home details (water source, number of bathrooms, space for equipment).
- Share any past RO or under‑sink units you want integrated.
We serve St. Louis and nearby cities like St. Charles and Wentzville.
