Whole-Home Water Filtration in Peoria, Illinois
A whole house filter changes taste and smell at every tap. It won't soften water, and it isn't a PFAS fix unless the product says so.
A whole house water filter in Peoria, IL costs about $1,129–$3,541 installed (HomeAdvisor national range), with activated carbon units at $800–$1,500. Carbon mainly removes the chloramine taste of Illinois American Water's disinfected supply. It doesn't lower hardness, so most homes here pair it with a softener.
Chloramine and carbon
Illinois American Water disinfects Peoria's water with chloramine and reported a running average of 2.9 ppm in 2025 (2025 Annual Water Quality Report). That keeps the water safe in the pipes, and some people notice the taste. Chloramine is harder to remove than plain chlorine, so ask for catalytic carbon sized to your home's flow rate. A backwashing tank lasts years; cartridge housings cost less but need regular changes.
PFAS: what Peoria's report actually shows
Illinois American Water says Peoria's system was sampled in the 2021 Illinois PFAS statewide investigation, that results showed PFAS above the Illinois EPA health advisory level, and that follow-up monitoring continues. Its 2025 table lists PFOA averaging 2.1 ppt and PFOS averaging 2.5 ppt (2025 Annual Water Quality Report). EPA's 2024 limits are 4.0 ppt each for PFOA and PFOS, with compliance due in 2029; in May 2026 EPA proposed letting systems request an extension to 2031 (U.S. EPA).
If PFAS is your reason for filtering, choose a product whose NSF/ANSI certification lists PFOA and PFOS reduction, and ask the utility for its UCMR 5 results, which it offers on request.
Filter and softener together
With both, the filter usually goes first so carbon protects the softener resin from chloramine. Neither one removes lead from household plumbing; that is a point-of-use job for reverse osmosis or a filter whose certification covers lead. The softener and filter costs for Peoria, IL are listed together.
What a whole-home filter won't fix
- Hardness. Calcium and magnesium pass straight through carbon, so scale keeps forming.
- Lead from plumbing inside the house, which enters after the filter.
- Sodium. Carbon leaves it in; reverse osmosis takes most of it out.
- Neglect. Spent carbon stops working and can shed what it caught, so replacement dates matter.
Questions homeowners ask
Is a whole house filter the same as a sediment filter?
No. A sediment filter catches grit and sand. Carbon changes taste and odor. Whole-home setups often use a sediment stage ahead of the carbon.
How often does the carbon need changing?
It depends on the design and your water use. Large backwashing tanks can go years; cartridges are changed on a schedule the maker sets.
