Homeowners across Lake County and the greater Chicagoland area deal with water that ranges from very hard municipal supplies to iron-heavy private wells. If the water at your tap looks cloudy, tastes metallic, smells like a swimming pool, or leaves crusty white scale on faucets and glassware, a properly sized whole home filtration system can fix it at the source. HT Strenger has been sizing, installing, and servicing residential water treatment equipment in northern Illinois since 1911, and we work with municipal and well-water homes alike.
Whole Home Water Filters.
Your water may also contain things you can’t even see, such as nitrates or other potentially harmful contaminants. If your water looks, tastes or smells bad, remedying the water at each tap as well as providing the best, purest drinking water is the answer.

Reduce Sediment, Chlorine Taste and Odor.
The water in your home may have several issues that need to be corrected, from hardness (mineral deposits) and turbidity (suspended dirt) to bad tastes and smells (chlorine odor).

What’s actually in northern Illinois water
Most Chicagoland municipal water is drawn from Lake Michigan and treated with chlorine or chloramine to control bacteria (see the EPA National Primary Drinking Water Regulations). It’s safe to drink, but the residual disinfectant is what gives it that pool-water taste. Homes on private wells in Lake, McHenry, and Kane counties are often over 180 mg/L in calcium carbonate, which the USGS classifies as very hard. Iron staining on porcelain, sulfur smell from hydrogen sulfide, and elevated nitrates near agricultural areas are common well-water issues. Older housing stock in communities like Waukegan, Libertyville, and Barrington may also have legacy lead service lines or interior copper joined with lead solder.
How a whole-home system is put together
A complete system usually stacks several stages in series at the point where water enters the house. A 5 to 20 micron sediment pre-filter catches sand, silt, and rust flakes so the downstream media isn’t overwhelmed. A catalytic carbon filter tackles chlorine, chloramine, taste, and odor, and helps reduce many volatile organics. A softener with ion-exchange resin swaps calcium and magnesium for sodium to protect water heaters, dishwashers, and fixtures. For drinking and cooking, most homes add a point-of-use reverse osmosis unit under the kitchen sink that pushes water through a semi-permeable membrane to remove dissolved solids, lead, and a wide range of contaminants including certain PFAS compounds.
Whole-house versus point-of-use
Whole-house treatment protects every fixture, appliance, and pipe in the home. Point-of-use covers a single tap, usually the kitchen sink. Most homes benefit from both: whole-house for softening and chlorine reduction, plus a dedicated RO faucet for drinking water. If you’re on a well with iron or sulfur, add-on stages like a manganese greensand or air-injection oxidation filter go in ahead of the carbon and softener.
Service, testing, and what to expect long term
Sediment cartridges typically need replacement every 6 to 12 months. Softeners want a salt refill roughly every 4 to 8 weeks and a resin cleaning every year or two, especially on iron-heavy wells. RO membranes last 2 to 5 years. We recommend a baseline water test before installation so the system is matched to the actual water chemistry, not a guess. Well owners should retest annually for bacteria and nitrates.
