Water Filters that Remove Iron

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.

This is one of the more popular house filter systems which addresses water problems related to manganese, iron in well water, and sulfur to name a few.  

The filters, fittings and housings that are used on the Home Master Filter will ensure that you have a regular supply of good pressure as it improves the water flow.

If your water pressure is good, the water filter can filter up to 15 gallons per minute.

The Home Master HMF3SDGFEC is ideal for a household that faces well-water contamination. This product will not work as efficiently in a city as it does not work with chlorinated city water.

For city water you should consider the HMF2SMGCC.

The 3 stages of this water filtration system ensure that your well water is free from contaminants such as iron, manganese, pesticides, and herbicides. Odorless, clear, and clean water will flow through every faucet in your house with this system.

View Features and Pros/Cons

Features We Love

  • The efficient high-quality sediment filter which is capable of removing any particle that is larger than 1 micron.
  • Removes 95% of iron from your well water.
  • The longevity of the activated carbon filter, which has a filtering capacity of 100,000 gallons.
  • Reduction on frequency of maintenance because of the larger filters.


  • 95% of the contaminants in your water source can be removed with this efficient water filter. Iron, sediment, manganese and other chemicals that can change the taste of your water are easily removed.

View On Amazon

Some of the best reverse osmosis water filters are made by iSpring, so we weren’t too surprised to discover that their whole house systems were equally efficient.

The WGB32B-PB is a tad pricier than the other models from iSpring, but it is one of the best whole house systems for treating well water.

This filter system not only removes iron and regular water contaminants, but it also removes dangerous heavy metals like lead and mercury. The WGB32B-PB filtration system with its three stage filtration is extremely efficient yet doesn’t compromise on the water flow.

The three stage filtration requires minimum maintenance and works very well to remove various contaminants.

At the first stage, the high capacity polypropylene sediment filter brings filtration down to 5 microns. Most of the bigger sediments are removed in the first stage.

View Features and Pros/Cons

Features We Love

  • You can interchange the housing and cartridge and switch the filter  around to suit different kinds of housing
  • Removes about 90% of iron.
  • The longevity of the cartridges which last up to a year for a family of four.
  • The special FCRC25B filter which removes heavy metals.


  • Long lifespan of the filter
  • Ideal for most well water contamination
  • Capable of removing dangerous heavy metals like lead and mercury.
  • Good water flow of 15 gallons per minute.
  • Affordable replacement filters.


  • The replacement filters are a little tough to install singlehandedly.

The CTO Carbon Block filter in the second stage uses components that maximize the efficiency of filtration.

Thanks to the higher density of these carbon filters, you get clean, odorless and clear water in all your taps.

This filter is also very effective in removing pesticides, herbicides and other industrial chemicals. It also gets rid of 90% of iron and chlorine from your water. Both these initial filters have a capacity of filtering 100,000 gallons of water.

The final stage of filtration effectively brings the lead contamination down to below 15 ppb. This special FCRC25B filter is only included in this model as it is meant to target the heavy metals in well-water.

APEC 3-Stage Whole House Water Filter

View On Amazon

The APEC 3 Stage whole house water system will ensure clean, clear, odorless and iron free water to every faucet in your house.

The fast flow rate of the system is ideal for the whole house, industrial applications or light commercial use. The 3 stage filtration cycle begins with bigger sediments and can trap particles as tiny as 30 microns.

We think one of the reasons why you should consider this system is that it comes preassembled.

This means that you will not have to break your head about how to install the unit. No additional parts are required for the assembly and it also has pre-drilled holes to easily mount it on your wall.

You may however, need to drill holes into your wall for the screws to fit in.

The 20-inch big blue whole house water system removes iron, chemicals, and other sediments to give you clean, clear water. 

After the installation of this unit, you will notice the difference to your drinking water. The three stages effectively remove all contaminants including iron.

View Features and Pros/Cons

Features We Love

  • Straightforward and Easy Installation process.
  • Removes iron up to 90%.
  • Washable and reusable filters help reduce cost.
  • Comes preassembled.


  • Fast flow rate
  • Preassembled and ready to mount
  • Filters are easy to replace.
  • Filter housings are durable and can withstand a wide range of pressure variations and chemicals.
  • Effectively removes iron, pesticides and herbicides.


  • No mechanism to notify you when the filters need to be replaced.

In the first stage of the filtration process sand, dirt, silt, scale and rust particles down to 30 microns are trapped. The durable polyester filter is washable and can also be reused.

We like the pleated design of the filter; it is capable of trapping larger amounts of dirt.

Any excess iron that has been able to escape the first stage of filtration is further reduced in the second stage. High purity manganese dioxide is used to reduce the iron content.

In addition, the metallic taste is also effectively removed in this stage as the soluble ferrous iron is converted into insoluble ferric iron.

The insoluble ferric iron is adsorbed by the carbon filter in the final stage.

This cartridge which is composed of radial flow granular activated carbon effectively treats the iron.

The taste of your water is further enhanced by the removal of chlorine, organic compounds are odors by the carbon filter.

With this filtration system from APEC you can be sure of softer skin and smoother hair.

Air Injection Silver Water Filter – Air injection Silver AIS10-25SXT AFW Water Filter

Air Injection SYstem iron filter
View On Amazon

The difference between using this AFW Air Filter Injection Systems and other water filters is that you do away with chemicals.

These systems use the process of oxidation to get rid of contaminants in your water. During the oxidation process, the contaminants come into contact with oxygen. They react with the oxygen and are released as oxides.

During the backwash cycle, the Air Injection System creates a bubble of pressurized air at the top of the tank.

The contaminants in the water are then oxidized and trapped by the air in the tank.

Every couple of days the contaminants are rinsed out during the automatic backwash. The air bubble is replenished by this process.

Unlike other air injection systems, this Air Injection System has only one tank for the entire oxidation process.

Older systems usually consist of two tanks or a Venturi valve for injecting air into the water. By doing away with a separate tank, downtime and maintenance costs are considerably reduced. 

View Features and Pros/Cons

Features We Love

  • The stainless steel bypass valve makes servicing and maintenance easy.
  • Eliminates the need for chemicals as it uses the principle of oxidation.
  • Ease of installation.
  • Appropriately priced.


  • The unit is easy to install.
  • It comes with just one tank instead of two for the filtration process.
  • Free drinking water bottle.
  • It has an automatic backwash system and it regenerates the air needed for filtering your water as often as possible.


  • The backwash cycle uses about 60 gallons of water so it can be a little expensive if you pay for your own water.

The Air Injection system uses a specially patented piston for the oxidation process.

During the oxidation process, the oxidized iron and sulfur are trapped in the filter media till it is washed out during the backwash cycle.

This chemical free system has the capacity to remove higher contaminant levels than most other tank systems.

The process of combining air injection with the iron trapping media helps in removing most contaminants. Iron, manganese and sulfur are removed without the addition of harmful chemicals.

Backwashing automatically takes place but can be very loud especially if it happens at night. However, you can reprogram this feature to set it to a more convenient time. The digital SXT controller is easy to use.

One point to be noted is that you will require 1” threaded connectors for the inlet and outlet connections. These are not part of the items in the box.

Best UnderSink Iron Filter – Home Master TMHP Undersink RO Water Filter

Home MAster TMPH iron filter image
View On Amazon

The Home Master TMPH RO UnderSink water filter is a highly sought after RO water filter. Why?

It’s one of the few reverse osmosis systems with more than 5 filtration systems.

Reverse osmosis has proven to be one of the most effective solutions to getting rid of contaminants in your water. The 9 stage purification process of this model will ensure an increased level of pure water.

Another thing we liked about this system is that unlike most RO systems, there is very little wastage of water.

Water wastage is in the ratio of 1:1, which means for every 1 gallon of clean water there is an equal amount of wastewater. The reason for this reduction in wastewater is the permeate pump.

By design, the input pressure is increased with this pump so there is less water wasted.

The UV light is an added bonus as it will destroy 99.8% of the microorganisms that could be in your water. Natural water source are generally high on microorganisms.

View Features and Pros/Cons

Features We Love

  • Iron pre-filter that protects the RO membrane.
  • UV filter to eliminate micro-organisms.
  • Permeate Pump that maximizes water pressure.
  • 9 stages of purification.
  • Removes j98% of iron.


  • Durable filters which need to be changed only once a year.
  • No wrench required to change filters, making it quick and easy
  • Adds minerals twice to enhance the taste of water
  • 98% of iron, heavy metals, chemicals and other contaminants are removed during purification stages.
  • Color coded installation process for better understanding


  • Slightly audible during the purification process.

One thing that you need to keep in mind is that a standard 110V power outlet is required by a UV filter.

With the remineralization filter, the system is able to raise the pH to be more alkaline by reintroducing safe minerals into the water. This significantly improves the taste of water.

Setting up this filter system is pretty simple. The instruction manual is simple enough to follow.

Home Master has also made a series of 6 videos to further help with the installation process. The only thing that you may find a tad difficult to do is drilling a hole on the sink top for the faucet.

The modular design of this system helps in the ease of changing filter elements. Each filter has its own individual housing which is changed along with the filter.

No tools are required for the replacement of filters.  Just make sure that the space under your sink is not too cramped or it could be a problem during maintenance.

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 Osmosis – These 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

Image – Pixabay

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.

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?

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

A water softener treats hard water by removing the minerals calcium and magnesium which cause hardness. Salt and ion-exchange is used to remove the hardness. Salt-less systems are also available.

House owners usually install both these systems for a complete filtration since water softeners don’t remove all the iron in the water.

What is the cheapest way to remove iron from well-water?

Aeration is one of the cheapest methods of removing iron from well water. Low-cost oxidation filters are effective. A manganese green sand with aeration is good because iron is oxidized as soon as it comes in contact with it.
