Water across the Twin Cities region can vary widely depending on source, treatment method, and local geology. Many homeowners experience taste, odor, staining, scale, and potential contaminant concerns that affect comfort, plumbing, appliances, and long-term water safety. Commers designs treatment systems based on measured conditions—not assumptions—so each problem is addressed at the source.

Municipal water often contains chlorine or chloramines for disinfection, which can leave a noticeable chemical taste and odor. Private well systems may develop hydrogen sulfide or sulfur bacteria, producing the familiar rotten egg smell. These issues can affect drinking water, bathing comfort, and even indoor air during showers.
Hard water is common throughout Minnesota and causes:
Iron in well water and some municipal sources can cause:
Both ferrous (clear-water) and ferric (red-water) iron require different treatment strategies.
Organic tannins from decaying vegetation can cause:
Sand, silt, clay, and rust particles can enter water lines and cause:
Groundwater and surface water may contain:
These compounds can affect taste, odor, and long-term exposure risk.
Per- and polyfluoroalkyl substances (PFAS) and microscopic plastic particles are emerging concerns in many Minnesota water sources. These contaminants are persistent, difficult to remove, and require advanced carbon and membrane-based treatment.
Depending on plumbing materials and aquifer conditions, water may contain:
The Commers Whole House Water Refiner is designed to treat the most common Minnesota water issues at the point of entry. It delivers soft, conditioned water while reducing chlorine, iron, and many chemical contaminants—protecting plumbing, appliances, and water quality at every tap.
What it helps address:
Key performance features:
Available in multiple sizes and paired with properly sized brine tanks, the system is selected based on professional water analysis to match both contaminant levels and household demand.
Municipal water is disinfected with chlorine or chloramine to protect public health. While effective, these disinfectants can leave a noticeable taste and odor. Whole-home carbon filtration and refining systems can significantly reduce these compounds before water reaches your fixtures.
Hydrogen sulfide gas and sulfur bacteria commonly occur in private wells. They create unpleasant odors and can contribute to slime buildup in plumbing. Proper oxidation and filtration systems are used to remove sulfur and control related bacteria.
Yes. Much of the Twin Cities region has naturally high calcium and magnesium levels. Hard water causes scale buildup, soap inefficiency, and premature wear on water heaters, dishwashers, and washing machines.
Iron in well water or older municipal lines can oxidize and leave reddish-brown stains. Both dissolved (clear-water) and particulate (red-water) iron require specific filtration and conditioning strategies to prevent staining and plumbing fouling.
Tannins from decaying organic material can leach into groundwater, creating yellow or brown discoloration. These organic compounds often accompany well water and require specialized media or carbon treatment.
Runoff and groundwater movement can introduce herbicides, pesticides, VOCs, and industrial byproducts into some water supplies. Advanced carbon and membrane-based systems are used to reduce these compounds when testing indicates their presence.
PFAS and microplastics are emerging contaminants found in some Minnesota water sources. They are persistent and require high-performance carbon and reverse osmosis technologies for effective reduction.
Total Dissolved Solids (TDS) represent the overall mineral and salt content in water. High TDS can affect taste, scaling, and appliance efficiency, and may indicate the presence of undesirable contaminants.

Professional water testing and system sizing ensure the right technology is selected for your specific contaminants, usage patterns, and plumbing demands.
