How much does a whole house water filtration system installation cost?

Installation cost for a whole-house water filtration system varies by system and home. A technician will confirm pricing after an in-home evaluation. We install RO, carbon, and UV systems, plus H2O Harmony whole-house conditioners and softeners, so equipment and labor can differ. We provide a free water test with any other service call to guide the right setup. Same-day service is available in Denver and nearby cities.

Cost factors to expect:

• System type and capacity (whole-house vs. combo softener)
• Plumbing changes or main-line tie-in
• Filter stages or UV add-ons
• Replacement vs. new install
• Access and location
