Signs You Need an Iron Water Filter
Iron is common in Wisconsin and can cause noticeable problems throughout your home. If you notice any of the following, it may be time to install an iron filter for well water:
- Brown, red, or orange stains on sinks, tubs, and toilets
- A metallic taste in your water
- A metallic odor in your water
- Rust-colored laundry or stained fixtures
- Orange buildup around faucets and drains
- Clogged plumbing or appliances from iron deposits
- Rotten egg odors (when hydrogen sulfide gas is also present)
- Slimy buildup caused by iron bacteria
- Rust particles in water
A professional water test can identify the type and amount of iron in your water. This will help determine whether well water iron filtration is necessary.

Before choosing a water treatment system, it’s important to understand what’s actually in your water. Our team offers professional water testing to identify any issues so we can recommend the solution that fits your home best.
Every area in Southeastern Wisconsin has unique filtration needs. We’ll be happy to test your water to determine the best filter option.
Why Wisconsin Well Water Often Contains Iron
Iron is a naturally occurring mineral found in the groundwater throughout many parts of Wisconsin. As water moves through iron-rich soil and rock, it can dissolve these minerals before entering private wells. As a result, many homeowners experience iron stains, metallic-tasting water, and other common water problems.
Iron is often found alongside manganese and sulfur-reducing bacteria, making professional testing an important first step. At Guthrie & Frey Water Conditioning, we test your water to identify the source of the problem and recommend the right iron water filtration solution for your specific water conditions.
Types of Iron in Well Water
Not all iron is the same, and identifying the type of iron in your water helps determine the best treatment solution.
Ferrous iron, also called clear water iron, is dissolved in water, so it may look clear when it comes from the faucet. After it’s exposed to air, it oxidizes and can leave orange or brown stains on fixtures, laundry, and plumbing.
Ferric iron, often called red water iron, has already oxidized before it reaches your taps. It appears as visible rust-colored particles that can make water look cloudy or discolored and may clog plumbing fixtures and filters.
Iron bacteria feed on iron in well water and create a slimy buildup inside pipes, plumbing fixtures, and water treatment equipment. They also cause unpleasant odors, and the slime can reduce water flow.
A professional water test can identify the type of iron in your water. This can help determine whether an Iron Curtain water filter system or another filtration solution is right for you.

What Is an Iron Curtain Water Filter?
An Iron Curtain® water filter is a whole-house system that removes iron, manganese, and sulfur odors from water. It uses a combination of air injection and filtration media to oxidize dissolved iron and capture it before the water enters your plumbing.
An Iron Curtain water system helps eliminate rust-colored stains, metallic tastes, and unpleasant odors while protecting plumbing and appliances from iron buildup. It’s an effective solution for many Wisconsin homeowners who rely on private well water.
Contact Guthrie & Frey for well water services in Wisconsin, including iron removal.
How Iron Water Filtration Works
With Iron Curtain systems, there are multiple stages. First, air is introduced into the water to oxidize dissolved iron, changing it into solid particles. As the water passes through the filter media, these particles are captured and removed.
Many Iron Curtain filter systems also perform automatic backwashing to flush away trapped contaminants and keep the system operating efficiently. The result is cleaner, clearer water throughout your entire home.
Iron Curtain Water Filter Maintenance
Routine maintenance helps keep your system operating at its best. Most systems automatically backwash to remove accumulated iron and other contaminants, reducing the need for frequent manual maintenance. However, regular inspections and professional service help ensure the system continues to remove iron effectively and operates as designed.
At Guthrie & Frey Water Conditioning, we provide maintenance for iron water filters in Wisconsin. Our goal is to help homeowners enjoy dependable, high-quality water year after year.

Q: Why does my tap water leave orange stains?
A: Orange stains on sinks, tubs, and toilets usually mean there’s high iron in your water. There are two common types of iron found in well water in Wisconsin:
- Ferrous iron (clear-water iron): This form is invisible when it first comes out of the tap, but turns orange when it reacts with oxygen. It may give your water a metallic taste and cause rust stains. Sometimes a water softener can remove low levels of ferrous iron, but not always.
- Ferric iron: This type is already oxidized, so it makes water appear orange or cloudy right away. Like ferrous iron, it may be filtered by a softener if levels are low.
Iron bacteria can also cause staining. These bacteria aren’t harmful to your health, but they can stain fixtures, create slime that may clog pipes, and cause foul odors. To remove iron bacteria, a disinfecting treatment such as chlorination is usually needed.
Q: What is the best water treatment for high iron levels?
A: If you have higher levels of iron in your water, a standard softener won’t be enough. The Iron Curtain system is an advanced iron filter for well water. It removes both iron and sulfur odors, leaving your water clean, clear, and stain-free.
Want to know what’s in your water? Schedule a free water test with Guthrie & Frey today.
Q: How often do iron filters need maintenance?
A: With proper care, an Iron Curtain system can last many years. We recommend servicing your iron filtration equipment every 4 to 6 years to keep it running efficiently. As a helpful reminder, we send out a maintenance postcard 4 years after your last service.
Some homeowners prefer a “maintenance-as-needed” approach. However, skipping routine maintenance can lead to bigger issues or more costly repairs down the road. The life and performance of your iron filter depend on your water quality and usage. Regular maintenance ensures your system continues removing iron, odors, and minerals effectively.
Q: What is the life expectancy of an Iron Curtain System?
A: Typically, Iron Curtain filtration systems have a life expectancy of 15 to 20 years.
Q: What are the signs my iron filter needs service?
A: If your Iron Curtain filter system needs maintenance, you’ll usually notice warning signs:
- Low water pressure: If your water pressure drops, your iron filter may be restricted. A quick way to check is to put the system in bypass mode and turn on a faucet. If the pressure improves, it’s time for routine service.
- Spitting faucets: If water “spits” out when you turn on a faucet, there may be an issue with the system’s check valve. This often requires professional cleaning or replacement of the valve.
If you notice either of these issues— or if your water no longer looks or smells clean —schedule a service visit today.
Q: How do I know if my water contains iron?
A: You can see if your area has a prevalent iron presence by finding your location here. However, it’s important to remember that iron can get into any well water supply. If you want to truly understand your water, schedule a free water test with our professionals!
Q: Do you offer iron filter system installation?
