According to the Environmental Protection Agency (EPA), about 15 million Americans depend on well water for drinking and other uses.

Well-water can sometimes be pretty high on contaminants, like lead, nitrates, and iron.

Besides altering the taste and smell of water, iron stains almost every surface that it comes in contact with. If you have reddish brown water coming out of your faucet, chances are your white clothes have a brown tinge too.

However, don’t despair.

If you’re looking for a solution to your problem, there are plenty of options to choose from.

We reviewed some of the best iron filters for well water. Here are out top picks.

Best Softener For Iron Removal:


Pentair WS48-56sxt10 Fleck Water Softener

According to a survey, around 85% of the people in the US receive water that has calcium and magnesium in high quantities. This is considered to be hard water. When water passes through elements like gypsum or magnesium, the minerals they constitute become a part of the water it comes in contact with. Even if hard water does not cause harm to your health, it can cause a variety of problems like clogging issues in your appliances.

The Pentair water softener has a mechanism that helps in extracting elements like iron, magnesium and calcium from the water and making it soft again. It features a brine tank and a mineral tank. Municipal water first enters the control valve and through the valve, it reaches the mineral tank. The mineral tank consists of ion-exchange beads that extract magnesium and calcium ions and discharge sodium ions. The number of ions that make the water hard is evaluated in grains. In a home consisting of four members, around 3,200 grains should undergo softening treatment every day.

Installing the device is a very easy process. It comes with a USB drive that has all the instructions you need to set it up in your home. Apart from a lubricant and a sanitizer pack, you also get a hardness test strip that gives you an idea about the degree to which the hard water has been softened. The brine tank has the capacity to hold around 250 pounds of salt. It has brine at the bottom. During the regeneration process, the brine solution passes through the mineral tank.

One thing you need to remember is the fact that the brand Fleck (Pentair) does not manufacture water softeners. It manufactures control valves that are used in the water tank manufactured by another company. The upgraded crosslink resin raises the life expectancy or durability of the beads. You get a five-year warranty period on the control valves and the tanks come with a ten-year warranty.

Health Risks Posed By Iron

Image – Dr. Cappellini

Iron is listed as a secondary contaminant by the EPA.

This means that iron does not have a direct bearing on health if consumed, but when mixed with bacteria, it can be a health risk. The secondary maximum contaminant level (SMCL) for iron as laid down by the EPA is 0.3 mg/L.

  1. According to the EPA, the problems related to secondary contaminants are put into three categories.
  2. Aesthetic effects – this relates to the taste, color and odor of the water due to the contaminants. Iron makes the water reddish brown and has a metallic taste.
  3. Cosmetic effects – relates to the effects that a contaminant can cause to the skin and other physical attributes of a person. Presence of iron in water can cause dryness of skin and in some cases, a change in the color of hair.
  4. Technical – relates to the corrosive action of contaminants which can have economic implications. Iron is highly corrosive and causes staining and clogging of pipes. Iron can also cause scaling in pipes.
  5. The WHO states that 1-3mg/liter of iron concentrations in water are acceptable for drinking. Unfortunately, most well waters have iron content that exceeds this limit. Thus ingesting/using water above the limit can lead to Iron overload (IO) which is a condition that is usually associated with the inability of the body to handle excess iron.

If left untreated, iron overload can lead to a serious condition called hemochromatosis which can damage the body’s organs. This can also lead to other chronic problems like liver and heart disease and diabetes.

Here’s a true life story of Rich Golden.

Here’s what Dr. Mercola has to say about excess iron in the body.

Testing For Iron in Water

If you’re concerned about the level of contamination in your well-water, a good idea is to get it tested. There are many reliable home testing kits that will give you an idea of the contaminants in your water.

The JNW Direct Water Test Kit and Watersafe WS425W Well Water Test Kit are good for detecting contaminants.

However, if you’re not too confident about these kits you could always use a water sample kit from a certified laboratory.

You can find a list of certified laboratories in the United States on the EPA website.

In addition to this, some local health departments conduct free tests on private wells.

A test will also determine the levels of contaminants present in your water. According to the EPA standards, the SMPL for iron in water is 0.3 mg/L.

Anything above this limit will discolor your water and give it a metallic taste.

What kinds of iron are present in water?

Image – GrisWold

Four types of iron are in found in water.

  • Oxidized iron has red particles which are clearly visible when the water flows through a faucet. This insoluble iron clogs the pipeline or your household appliance.
  • Clearwater iron which is soluble is generally not noticed until it comes out of the faucet. The discoloration happens when the water is exposed to the air for some time. This is because it mixes with the oxygen in the air to form Ferric oxide which is commonly known as rust.
  • Colloidal Iron does not show up as red particles but makes your water look cloudier. It is difficult to filter this type of iron as the particles are extremely small in size.
  • Bacterial Iron is evident as reddish/green slime build up in the flush tank of your toilet. It’s not easy to get rid of this type of iron and the best way to do it is by chlorinating the entire water system.

A water test will give you an idea of the type of iron in your well water.

How Do You Remove Iron In Your Well Water?


One of the most effective ways of removing iron from your well water is by the process of filtration or flocculation.

Oxidized iron is generally easy to remove by this method as the insoluble particles stick easily to the filter. However, smaller particles of colloidal iron will not be easily removed by a regular filter. Use a membrane filter of .22 micron for this.

All the systems that we’ve listed above can effectively treat this problem.

Ion Exchange

Clear water iron is more difficult to get rid of as it is soluble in water. When ferrous iron is oxidized it first forms ferric ions.

These ions combine with free hydroxyl ions in water to form sticky gelatinous ferric hydroxide. Therefore it is necessary to use a filtration system with the ion exchange function.

A good water softener which targets iron is also a good option.

However, oxidized iron or iron bacteria present in water will coat or clog the ion exchange resin if the softener is not specifically meant for iron removal. The Iron Pro2 Combination Softener is a good system for this.

Oxidation combined with filtration

Aeration of water contaminated with soluble iron will help in oxidizing the ferrous iron.

With a sufficient supply of oxygen, the iron in alkaline water will be fully oxidized to form insoluble ferric hydroxide.

This precipitated iron can be easily removed with a variety of filter media.

The Air Injection Silver AIS10-25SXT AFW Water Filter is ideal for this process. The single tank will ensure that there is no fouling at the head as the iron is filtered out from one unit.


The only effective method for getting rid of bacterial iron is by chlorination. If the level of bacteria is high then shock chlorination is recommended.

However, you will need to have an alternate source of drinking water during this procedure. Once the treatment is completed you can use an activated carbon filter to get rid of the excess chlorine.

Manganese greensand is also effective for filtering out the iron precipitate.

What are the types of filtration systems that filter iron?

There are 4 major types of whole house filtration systems in the market.

Activated Carbon Filter – This type of filter is ideal for most dangerous chemicals as the surface area that it covers is extensive.

Activated carbon is carbon with greater absorptive power because of the increased surface area.

AC has been specially treated to achieve this. The EPA recommends this treatment for dealing with 14 pesticides and herbicides.

The downside to using an AC filter is that it is not very effective in removing metals like copper and other inorganic impurities.

Reverse OsmosisThese systems are one of the most highly recommended as the technology that it uses removes almost all harmful contaminants.

A semi-permeable membrane traps impurities when water is forced through it.

The treated water is stored in a tank on the other side of the membrane while the trapped impurities are flushed out through a pipe.

This system also uses activated carbon filters to trap other impurities that can go through the membrane.

The downside to this system is that it requires a drain to flush out the impurities.

A lot of water is wasted too as it flushes out at least 5 gallons of wastewater for every gallon of clean water. These systems are also quite expensive.

UV Filters – These filters are the latest in the water purification industry but they are gaining in popularity. The technology that the Ultra Violet filters use is pretty straightforward.

Harmful microorganisms are targeted by UV rays, which results in their destruction. 99.9% of harmful microorganisms have been safely dispensed of with UV rays.

This filter has also been approved by the Food and Drugs Administration.

The downside to this system is that it doesn’t remove contaminants like heavy metals, herbicides and other impurities. The rays aren’t effective in murky water either.

Alkaline water ionizers – These ionizers separate water into 2 clusters – acidic and alkaline. The components which are acidic are flushed out through a hose at the bottom.

The alkaline water which is expelled through a spout at the top is used for drinking. Alkaline water is said to have some beneficial properties although these haven’t been scientifically proven.

The downside to these ionizers is that you need to have another purification system attached. While the system removes the acidic components, it does not target any living organisms.

Other Factors To Consider

A system that targets your specific needs

Before you begin to read the reviews of the filtration systems that are available in the market stop to analyze your actual needs.

If you are familiar with the kind of contaminants that exist in your water supply then you are good to go.

However, if you are not very familiar with the pollutants that exist in your water supply we suggest you talk to a professional.

The common contaminants in well water are the chemicals that get dissolved from agricultural runoff like pesticides, fertilizers and herbicides.

Other contaminants can include lead from old pipes, manganese, and iron. Manganese can be quite a pain because the staining of fabrics is often worse than the brown stains that iron leaves behind.

Whole house water filters are designed to tackle contaminants from well-water and municipal supply. However, there is usually a variation in the filters used, which is generally specified.

Once you’re absolutely sure about the kind of contaminants that exist in your water supply, you can go ahead and invest in a whole house water filtration system. Buy one that addresses your specific needs.

Flow Rate

When you invest in a whole house filtration system, remember that it is designed to do just that. The filtration system should purify the water to all your household outlets without hampering the pressure and supply.

If there is a drop in water pressure when you open multiple outlets, then the filtration system probably has certain limitations.

The flow rate of water is measured in gallons per minute (GPM).  A whole house system should not have a water flow rate of less than 10 gpm as this will not be efficient during peak use. This would result in low water pressure and an interrupted water supply.

All appliances which use water will normally have the required rate printed on them. A dishwasher usually requires 3 gpm, while showerheads use between 2.5 to 5 gpm.

The maximum flow to a toilet is 5 gpm. Families typically require a water flow rate from 15 – 40 gpm.

Larger homes will probably require about 25 gpm. Don’t break your head if these calculations are a bit too much for you, just seek the help of a professional.

What kind of filters would suit your home

The filters in whole house water systems can remove the main contaminants in your water.

However, if you want a foolproof filtration system that will give you 100% safe drinking water, then reverse osmosis systems are your best bet.

Reverse osmosis (RO) systems are priced much higher than the regular systems so that’s something you need to consider. We suggest using a smaller RO unit only for your drinking water along with the whole house filters.

You can set this up under your kitchen sink only to target your drinking source.

Size of Filters

Large filters are low on maintenance and have a more efficient water flow rate with better pressure.

One of the most important things you need to look out for is the port size of the filter.

The port size has a direct bearing on the water pressure that flows into your house. 4.5” x 20” is the recommended size for a whole house filter with a 1” port.

If you have a bigger household, then you will need filters with 1 ½ inch ports and a flow rate of 25 gpm.

Micron Ratings

The micron rating measures the efficiency of your filter. If the micron rating is smaller it means that the filtration is more effective. The problem with a smaller micron rating, however, is that it will significantly reduce the water flow.

You can see evidence of this in RO filters where the 0.0001 micron rating can bring the flow down to a trickle.

Common micron ratings are 50, 25, 10 5 and 1.

Life of the Filter

Replacing the filter cartridges can sometimes be a tedious task especially for someone unfamiliar with the technique.

So it’s always good to invest in filters which last longer.  The life of the filter depends on your water usage and also the quality of the water that it is filtering.

Good quality carbon cartridges will work efficiently to filter 100,000 – 150,000 gallons, which is a year’s supply of water.


Whole house filtrations systems cannot be pushed into a little corner as they take up a fair amount of space.

Before investing in one of these systems you need to be sure of the space. You will need some space around it too for installation and maintenance.

FAQs About Iron Water Filters

How long will an iron water filter last?

The most basic systems will require a replacement for the sediment pre-filter every three to six months.

On the other hand, the sub-micron post filter can be changed after 12 months. However, as soon as you notice the taste in your water, you should change the filter immediately.

One rule of thumb is to buy a pack of 3 to 6 filters and keep them at home.

What if I don’t replace my filters?

Water experts caution against not replacing filters as bacteria and mold could grow in it. In order to protect your health you should replace the filters at least once a year.

What is the difference between a water softener and an iron filter system?
