A whole house water filter cleans every tap in the home — sediment, chlorine, taste and odor. Here's the real 2026 installed cost.
THE SHORT ANSWER
The short answer
Whole house water filtration runs $850–$5,400 installed in 2026 (Homewyse: $990–$1,245 per system). The system runs $150–$2,000; labor $300–$800. Carbon filters are cheapest; multi-stage and UV systems cost more.
What it costs
A basic sediment/carbon filter runs $850–$1,500 installed. A multi-stage system with UV runs $2,500–$5,400. The system runs $150–$2,000; labor $300–$800. Filter replacements run $100–$300 per year.
- Basic carbon: $850–$1,500

Whole house vs under-sink
Whole house filters clean all taps — the choice if you have sediment or chlorine problems everywhere. Under-sink RO systems ($1,000–$4,000) give the purest drinking water but only at one tap. Many homes run both.
