✅ How Does Iron Get Into Your Well Water & Why It’s Bad: The Basics

Wells are designed in a way to utilize the water that is present underneath the ground, i.e., groundwater. Some also get their water from collecting rainwater or surface water stored in wells during the monsoon. 

Lately, well water has become one of the significant sources of water supply to households, with about 15% of the population getting their water supply from it. But well waters are much vulnerable to iron contamination as they get their water either from the underground or the surface water that comes down along rivers and rains. 

Since iron is the second most abundant mineral in the earth’s crust, it quickly gets added to and contaminates water sources. While the water from rivers and other sources comes down, it gets in contact with rocks. From these rocks, the waters take up iron minerals along the way.

This iron-containing water with other water minerals then flows down, and some of it directly goes to the wells, and the remaining gets added to the underground water, which again is supplied to the wells. This way, well water gets contaminated with iron impurities.

The presence of iron over 0.3 mg/L in well water leads to stained fixtures, pipeline blockages, and skin conditions like irritation, acne, and brittle and dry hair, among many other troubles. 

Here’s how you can remove iron from well water naturally!

What Makes the Presence of Iron So Bad?

  • Clogging: As the water with iron contamination flows via pipelines and faucets, it keeps collecting and storing the iron. Initially, the damage begins by causing pigmentation and reduced water pressure. If the same continues, it can lead to complete blockage of the pipelines. Eventually, you will be required to invest in repairing and replacing the fixtures and faucets. 
  • Staining: Even when present in low concentration, iron causes pigmentation and staining of appliances. It makes bathroom tiles or toilets turn reddish-brown or orange and damages the entire appearance of your household appliances. Iron-contaminated water can turn your beautiful white tiles into a pale yellow, ruining the entire look of your bathrooms. If used for washing, it leaves behind red, brown, or yellow stains ruining the equipment and clothes forever. 
  • Bacterial attack: Several bacteria feed off of iron present in water (especially organic iron). The buildup of these iron bacteria leads to smelly brown slime, appliance rust, and other damaging things.
  • Adverse health effects: While a low concentration of iron might be necessary for drinking water for humans (as it serves the requirement of iron in the body), consuming water with high levels of iron (more than 0.3 mg/L) might cause health issues like organ damage.
  • Hair and Skin Conditions: Using water with iron contamination for hair and skin wash purposes can have adverse effects. It might cause your hair to be dry and brittle. People with blonde hair might get orange stains on their hair. It may also cause the skin to wrinkle prematurely and, in some cases, even become the cause of skin irritation and acne.

Do Not Choose Your Best Water Filter for Iron Before Reading This

Do you know which type of iron filter is the best for your well water? You need a guide that can give you an account of all the factors that play a role in determining which filter will suit you the best.

Lucky for you, we are here with precisely that. In this section, we have mentioned all the major factors you must consider before investing in an iron water filter. 

Well, why wait any longer? Let’s talk business:

1️⃣ Water Quality

It is crucial to first assess your water quality. What exactly is the problem? What kind of contamination is the leading cause? 

Find out the level of iron contamination in your water. If it is more than 0.3 ppm of iron, it will significantly affect your drinking water quality. You will require specialized iron reduction systems like an air injection oxidizing system to deal with it. 

  • If your water has iron and chlorine contamination, you should get an iron and carbon block filter. This will help tackle both issues with ease. 
  • If you have hard water with too much iron levels, consider getting a water softener that effectively reduces iron impurities from the water.

Don’t forget to consider the pH of your water as well. Any water source with a pH lower than 7 might damage your house filter system and make it ineffective.

2️⃣ Filter Capacity

The filter capacity is the next thing to keep in mind. How much water can the filter treat on a minute-by-minute basis? There are filters available in the market with a variety of capacities. 

Most filters are designed to supply water to a two-bathroom house. There are filters available that can serve houses with up to 6 bathrooms. If you enjoy taking long showers, you should get a filter with a high capacity.

Filters with less capacity may cause a drop in water pressure. It is always better to get a filter that has a large capacity.

3️⃣ Filter longevity

Usually, whole house iron filters have a lifespan of up to 10 years. They may require you to change the individual filter cartridge every 6 months.

Crystal Quest filters cartridge

There is a greensand type of water iron filter available with different filter media; they don’t require much frequent changing and easily last up to 6-8 years. 

4️⃣ Installation and Maintenance Requirements

Whole house filters require you to install them at the point of entry of the water supply at your house. Anyone can do this with knowledge of plumbing and the system’s workings. It does require you to cut the pipeline and install a valve that everyone might not be comfortable with. 

There’s always the option to call in a plumber but keep in mind that it will cost you around $200.

Installation usually takes about one or two hours. Maintenance requirements of iron filters include changing the filter cartridge as needed, regular cleaning and ensuring everything is well-connected, no leakages, etc. 


Usually, it is recommended to invest in a filter that brings with it ease of installation and low maintenance requirements. 

5️⃣ Warranty

You do not want to be stuck with a damaged filter, do you? No. The filter needs to come with a warranty. A whole house water filter usually has a warranty of about 10-12 years, excluding filter cartridges.

Iron water filters come with a minimum 2-3 year warranty. Water softeners also have about a 10-year warranty on the tank and other parts and a 1-3 year warranty on the filter and bypass valve.

These are the 5 major considerations to keep in mind before investing in any iron water filter. We did our homework so that you won’t have to, researched and analyzed about 17+ whole house filter systems keeping in mind the above-listed considerations, and finally narrowed it down to the Top 5 whole house filter systems that will resolve all your well water problems.

Pentair Iron & Manganese Filtration System: Best Filter for Iron Bacteria Well Water

Pentair Whole House Filtration System: Pros

If you’re facing problems due to the buildup of iron bacteria, this might just be the best iron filter system for you. Pelican iron and manganese whole house filtration systems (coupled with their retention tank) are one of the finest filters available to resolve bacterial iron contamination in well water.

They have been certified by NSF and are indeed one of the most effective methods of dealing with iron-contaminated water.

  • There’s a 5-micron sediment Pre-filter that removes dirt and prevents clogging of the filter.
  • Then there’s an injector that adds bleach to the water. The bleach reacts with the bacterial iron and kills it, oxidizing any soluble iron in the water.
  • Then comes the retention tank; it stores the water right after adding bleach. It facilitates more contact time between the water and bleach, increasing its effectiveness.
  • The filter system contains a greensand filter. All the impurities turned into insoluble particles of iron are trapped in the greensand filter stage.
  • Lastly, these trapped insoluble particles are removed from the water.
  • The end-stage carbon filter finally removes all the excess bleach and organic chemicals. This filter for iron removal ensures the production of a healthy and contamination-free water supply. 

The pelican water filters come in two sizes: The WF4 has a filter capacity that can provide a flow rate of about 10 gallons per minute to 1-2 bathroom households. The WF8 filter can provide a water flow rate of 15 gallons per minute that can be suitable for houses with 4-5 bathrooms.


Maintenance requirements include changing the sediment filter every 6 months and the injector pump every 6-12 months. The greensand plus filter comes with a warranty of about 7 years. The rest of the filter come with a lifetime warranty. 

Pentair Whole House Filtration System: Cons

The only downside of Pentair iron and manganese water filter is that some people found the chemical feed too noisy.

Are Iron Filters Worth It?

We’ve talked a lot about iron filters by now. Let’s get to the main question: are they even worth investing in? Let’s weigh out the pros and cons of iron filters and find the answer. 

✔ Iron Filter for Well Water: Pros

  • Goodbye staining: Iron filters are very effective in removing the particles of iron that cause red or yellow, or brown staining of the pipelines and faucets. They eliminate the contamination and help keep your pipes, plumbing fixtures, and other appliances healthy for a longer period.
  • Better Taste: By removing the cause of contamination, i.e., iron minerals, iron filters enhance the taste of water. The presence of iron in water can give it a funny metallic taste. Iron filters remove the main source of impurity, i.e., ferric and ferrous iron, and provide you with healthy and tasty water. 
  • Elimination of other contaminants: Iron filters not only work by eliminating all the iron impurities present in the form of ferric or ferrous irons. Some whole-house filters even help eliminate other impurities like the buildup of iron bacteria and other harmful impurities like pesticides, sediments, manganese, Volatile Organic Chemicals, chlorine, sulfur, etc. 
  • Minimal maintenance: Most iron filters do not require much maintenance. Some contain cartridges that require changing only once or twice a year. Those that don’t have cartridges contain other media that last for up to 6-8 years without replacement.  

❌Iron Filter for Well Water: Cons

  • Expensive: Iron filters are an effective method for iron removal, but they come with a price, literally! Getting them installed may cost you anywhere from $1000 to $3000. 
  • Installation is tiresome: It is a great deal of work to get whole house iron filter systems installed at your house. You will need to call a professional to get it done, and the process can be a little weary. 

Even though installing the whole house iron filters may be a bit of work, they are indeed something worth investing in. They help improve the water quality to a great extent by resolving all iron-related troubles. 

Should You Use Iron Filters With Softeners?

Sometimes, it is best to use a water softener along with iron filters, especially when dealing with water that might have organic iron impurities. A Water softener works by the ion-exchange method and helps remove unwanted amounts of iron and other impurities from water. Water softeners with iron filters ensure maximum removal of iron contamination from water.

⭐ Types of Iron in Well Water (and Filter Type That Removes Them) 

There are quite a few kinds of iron that can be found in well water and contaminate it. Let’s discuss what these are and how you can tackle them. 

1️⃣ Ferrous Iron

Ferrous iron is also sometimes called clear water iron. The reason behind this is that the water coming out of the faucet appears to be clear. If left standing in a bowl or container for a while, the water will turn reddish-brown.

The best treatment for ferrous iron contamination in water is the manganese greensand filter type. It effectively treats water with up to 10-15 mg/L of iron contamination in water.

Although some might use water softener to treat ferrous iron-contaminated water, a greensand manganese water filter is much more effective to remove ferrous iron from the water. 

2️⃣ Ferric Iron

Ferric iron is also commonly known as red water iron. It causes water pigmentation, and the water from the faucets is red or yellow. Identifying ferric iron impurities is very easy due to this characteristic.

To remove ferric iron impurities, a manganese greensand filter is the best option. Apart from manganese greensand filters, you can opt for sediment filter, carbon block filter, or water softener.

3️⃣ Organic Iron

Water contaminated by organic iron may appear red, yellow, or colorless. Organic iron impurities are usually found in shallow wells or wells filled with surface water.

Reverse osmosis or distillation are the effective methods of treatment in this case. Organic iron prevents or slows oxidation, making water softeners and most iron filters a little less effective in treating the issue.

Chemical oxidation followed by iron filtration can also be a good treatment of choice to help remove organic iron impurities.

Got More Questions On The Best Iron Filter for Well Water?

1. What is an iron filter, and how does it work?

Whole House Iron Water filters are specially designed to resolve iron contamination issues in your water supply. The filters contain a media tank that has a naturally oxidizing agent. This agent oxidizes the soluble ferric and ferrous (iron) impurities and converts them into insoluble particles of iron. These insoluble particles are then easily removed by the filter.

2. How long does an iron filter last?

Iron filters last up to 6-8 years because they use oxidizing media like chlorine and other media beds instead of filter cartridges that need replacement every 6 months.

3. Can a water softener remove iron from well water?

No, water softeners efficiently remove impurities like calcium and magnesium through ion exchange. Still, when it comes to iron contamination or traces of insoluble iron in water, water softeners alone fail to work effectively.

4. What are considered high iron levels in well water?

Water with an iron concentration of 0.3 mg/L is considered high in well water.

5. How can I tell if there is iron in my water?

If your water has a rusty smell or your toilets and sinks have reddish-brown stains, your water is contaminated with iron which you need to address quickly.
