Water Softener Installation: What to Expect

Learn everything you need to know about getting started with your smart water softener.

Can you filter iron out of well water?

Yes, it’s possible to filter iron out of your tap water with the right filtration system. For example, Iron-Cleer is specifically designed to target this issue, which is particularly common in wells. However, Iron-Cleer isn’t just an iron filtration system for well water; it can also be used in homes with a municipal water source.

The best iron filter system for your water depends on a variety of factors, including:

What contaminants may be present in your water
What water quality issues you’ve noticed
Whether you’re looking for more advanced features, like controlling your system from an app
To determine which system is right for you, begin with a free, in-home water test and consultation. Your local water expert will determine what’s present in your water, including hardness and pH levels, then recommend the best type and size of filter.

Iron-Cleer doesn’t just address iron — it can also target hydrogen sulfide, which is often responsible for a rotten-egg smell when you turn on the tap.


If you have water quality concerns or contaminant issues beyond iron and hydrogen sulfide, there are plenty of other options available. Culligan whole home and reverse osmosis drinking water filtration systems come in different models designed to address various contaminant types, and a free water test and consultation can tell you which is best for your home’s needs.

Iron is a naturally occurring mineral that can be found in rocks, soil and more — and it’s all over North America. This means that water moving through the environment has plenty of chances to absorb iron before reaching your home, especially if you have a well. Note that iron can also be present in city water, often because the pipes may be corroding or leaching contaminants.

Do I need an iron filtration system and a water softener?

Filtration and water softening are two different processes. You may need both, particularly if you use well water, as iron and hard water issues often go hand-in-hand. Filtration addresses a wide variety of potential contaminants that may cause unpleasant odors, colors, tastes and, sometimes, health concerns.3 Filtration processes differ, but they often involve filtration media or a semipermeable membrane that traps or otherwise addresses contaminants.


Softening, on the other hand, addresses the issues responsible for water hardness — an excess of calcium and magnesium in your water. Although some softeners may also filter certain contaminants, such as chlorine, you likely still need a separate filtration solution for more comprehensive treatment.

Iron in water generally isn’t a health concern, but it can cause other issues that may be frustrating and — over time — expensive. For example, iron may leave rust-like stains on your clean laundry, dishes and fixtures. It can also clog your pipes and water-using appliances, reducing efficiency and lifespan. On top of that, iron sometimes gives your water an unpleasant metallic taste.

Iron-Cleer doesn’t use chemicals in the filtration process. Instead, it relies on oxygen and its interactions with iron and hydrogen sulfide to create better, cleaner water at every tap. Better yet, this means you can help the environment by using your home’s water instead of single-use plastic bottles.

Instead of harsh chemicals, the Iron-Cleer iron filtration system for well water and city water uses aeration — a process responsible for oxidizing dissolved iron and hydrogen sulfide. An air compressor provides the oxygen, and a unique media filter acts as an insoluble catalyst to enhance the natural reactions.

The system is separated into two tanks. First, water flows through the aeration tank, where dissolved iron and hydrogen sulfide become particulates. These particulates move to the second tank, called the catalytic multi-media tank, and are filtered out of your water supply.

The product … makes the water soft and soothing.

The equipment is running on its own and seems like a durable, smart, self-activating machine.
