Things to Consider When Comparing Iron Filters

When looking at different products we wanted to be able to compare them apples-to-apples specifically for iron, so these are the main criteria we took into consideration:


Ability to Remove Iron & Other Contaminants

The best iron filter for well water is going to be able to remove iron, but many filters go above and beyond by reducing other common and potentially harmful contaminants as well.

These are the different filter types used in well water systems, and the impurities they work on:

Filter TypeContaminants Removed
Air injection oxidizing (AIO) filterIron, manganese, hydrogen sulfide
KDF filterHeavy metals
Carbon block filterOrganic chemicals, foul tastes and odors
Sediment filterSilt, suspended particles, rust
UV filterBacteria, viruses, protozoa

Filter Lifespan & Capacity

The capacity of a filter refers to the number of gallons of water it is rated to filter before needing to be replaced, so it’s a direct measurement of the filter’s lifespan.

How long that translates to is going to depend on your household’s size and water usage, but a filter with a 1,000,000 gallon capacity will always last longer than one with a 100,000 gallon capacity in the same house.

Flow Rate

The flow rate is the water pressure that comes out of your fixtures and appliances. Some filters leave your pressure relatively untouched, while others can have a significant impact on flow. Too low of water pressure is one of the most common customer complaints when it comes to water filters.

Ease of Installation & Filter Replacement

Some systems make it easy to DIY the install – saving you the cost of paying a plumber. For others, it will actually void the manufacturer’s warranty if anyone other than a licensed professional does it. How often you have to replace the filter cartridges is also something to consider.


All manufactures make claims about their products’ performance, but some back them up by having those claims tested by independent organizations. The National Sanitation Foundation (NSF) and the Water Quality Association (WQA) are the two main labs that certify different products for meeting pre-set industry standards.

You can see our guide here for more information on certifications.


We made sure that all of the filters on our list are offering the best value for their price tags – no matter where they fall in the price range. When comparing different filters, you’re also going to want to look at the price of replacement filters and other maintenance requirements.

Iron Filter for Well Water Buyer’s Guide

Now that you know our top choices for the best iron filter for well water, this is some of the other information you’ll need to make the best purchase for your home’s needs.

What Is an Iron Filter & Who Needs One

An iron filter is a type of water filtration system that removes iron from your well water. The vast majority of homeowners with well water will have iron in their supply, but you can find out exactly how much by getting your water tested.

You can purchase water testing kits that will break down the ppm of iron in your water in addition to hydrogen sulfide and manganese – the other two most common well water contaminants, and many other organic and inorganic chemicals as well. Knowing what contaminants you’re up against will help you pick out the best filter to tackle them most effectively, and you can see our review of the best testing kits here.

If you have more than 0.3ppm of iron, the USDA recommends getting an iron water filter for your well. If your water tests under that amount, you’re still likely to need another kind of filter for whatever other contaminants are in your water but it won’t have to be an iron filter specifically.

The Science of Iron

By learning a bit more about what iron is and how it behaves, you’ll be better-equipped to deal with it in your water supply.

Types of Iron

There are 3 types of iron found in well water:

1. Ferrous
2. Ferric
3. Colloidal
4. Bacteria-associated

Ferrous iron is a water-soluble form of iron that stays dissolved in your water. It’s entirely clear, and you can’t tell it’s there without testing for it – except by the taste of your water and the red-orange stains it leaves. This is the kind of iron that has to be removed by special filters like the AIO or KDF systems.

Ferric iron is an oxidized form of iron, which turns it into a solid particulate that can be filtered by simply passing through a sediment filter. Ferric iron is essentially rust, which can change the color of your water, and it’s more noticeable since it’s in solid form.

Colloidal iron is the same form as ferric iron, but colloidal particles are much smaller – down to 0.01 microns in diameter. Most sediment filters remove particles down to 5 microns, so this form of iron can be easily missed by most filters. The good news – colloidal iron is not as common, and while you can find ultrafiltration systems that will remove it, most households can let it be and still stay below the 0.3ppm mark.

Bacterial Iron:
There are some species of bacteria that use iron as an energy source. These bacteria oxidize ferrous iron to its ferric form, and then they form annoying patches of rust, bacteria, and slime that sticks it all to your well’s pipes, pumps, and other plumbing fixtures. You usually have to chemically treat your well to remove them, but fortunately iron bacteria are less common than having just iron in your water.

Iron in Your Home

Iron is what gives blood its metallic taste, which you probably already know if you’ve ever accidentally bitten your lip. When iron is present in even moderate levels in your well, it gives your water that same metallic taste.

As you probably also know already, rust stains everything. It’s the iron in your water that causes the orange-red stains in your sinks, showers and toilets, not to mention your other appliances from your water heater to your coffee maker.

The most noticeable improvement from having an iron filter for your home is going to be the reduction of those reddish stains, and water that tastes better overall. In fact, that’s what most of the customer reviews love about the iron filters on our list.

Iron and Health

Iron, along with calcium, magnesium, manganese, and other naturally occurring minerals are completely normal to find in your well water. While these cause no harm and can even be beneficial to health in small quantities, excessive levels of iron can lead to health issues down the line.

Certain medical conditions such as hemochromatosis – which causes the body to increase absorption of iron – can lead to complications with the heart, liver, and pancreas if iron consumption is not limited.

Some skin conditions like eczema, for example, can also be aggravated by high iron levels and it can even cause extreme reactions in some cases. At the end of the day, using an iron filter is an investment in your health as well as your home.

Terms to Know

These are the common acronyms and terms that the manufacturers use to describe their products’ specifications:

  • Ppm: parts per million – or the milligrams of a substance per liter, is a measurement of the level of a particular substance in water.
  • Gpg: grains per gallon – hardness-causing minerals are measured as “grains”, so while iron would be measured in ppm, minerals like calcium and magnesium would be measured in gpg.
  • GPM: gallons per minute – this is how water pressure is measured and it’s commonly referred to as the flow rate.
  • Capacity: the number of gallons of water a filter can process over its lifespan
  • 4-stage, 3-stage, etc: refers to the number of filtration steps present in each system. An example of a 3-stage system might be a sediment filter, a KDF filter, and an activated carbon filter.


How Iron Filters Work

Iron filters targeting ferric iron are simple – they have pore sizes that are large enough for water to pass by but too small for ferric iron particles to follow.

On the other hand, since ferrous iron is dissolved, it must be oxidized to ferric iron by adding an electron to make it no longer water-soluble. Then it can be easily removed.

Types Of Filters

The main types of filters used to remove iron are air injection oxidizing filters (AIO), iron & sediment filtration media beds like KDF-85, ion exchange water softening media, and sediment filters.

AIO filters oxidize iron and other metals by passing the water through a pocket of compressed air. This forces the iron to become oxidized to ferric form, where it then travels to the filter bed below and becomes trapped. Eventually both the oxygen in the air pocket becomes depleted and the filter bed becomes clogged with particulates, which is why these filters have a built-in regeneration cycle.

During the regeneration cycle, there is a backwash of water through the filter bed that flushes out the accumulated particles and the air pocket is also replaced with fresh, oxygenated air.

KDF filters use catalytic media made of copper-zinc granules that oxidizes dissolved iron to its ferric form by adding electrons to the particles as they come into contact with the media. The ferric iron is then captured by the filter bed, and media must be replaced eventually as it gets used up. A backwash cycle can help prolong the filter life by removing the built-up ferric particles.

Most salt-based water softener systems use ion exchange media – sodium and potassium salts – to swap out the hardness-causing minerals in your water like calcium with salts like sodium. This process prevents mineral scale from forming in your home’s pipes and fixtures, and it can also work on small amounts of iron as well.

If you have less than 1ppm of iron in your well water, you can get away with using a standard water softener to remove it. If you have any more, you’ll either need to get a dedicated iron filter or increase the grain capacity of your water softening system – i.e. from 32,000 grains to 64,000.

Sediment filters, in addition to picking up the iron that’s already in ferric form, are great at stopping the other suspended particles in your water that could clog your filters and shorten their lifespan. It also works for those that the other filter types just aren’t designed to catch.

Advantages and Disadvantages of Iron Filters

These are the main pros and cons of using dedicated iron filters for your well water supply:


  • Reduces iron down to safe, USDA-approved levels
  • Depending on the filter type used, can also work on other heavy metals like manganese and harmful contaminants like arsenic
  • Improved taste of water
  • Reduced red-orange staining


  • Iron filters are often specific for iron and only a handful of other contaminants – if you well has other pollutants you’ll need additional filters
  • Like with any water filter, there can be a negative impact on flow rate
  • Some iron filters don’t come with a dedicated sediment filter, so you may need to add one
  • The backwashing regeneration cycle can be noisy on some models


What to Look For in An Iron Filter

These are the main features you’ll want to look for when considering an iron filter for your home:

Filter Lifespan

The longer the filter lasts, the less maintenance and upkeep you’ll have to do. Longer-lasting filters are also less likely to cost you as much money over the lifetime of the system. The lifespan of the filter (or filter cartridges) is usually written on the packaging or on the manufacturer’s website, and it can vary greatly depending on the filter capacity and the water use of the household.

Water Flow

You’ll want to get a system that won’t reduce water pressure beyond your household’s flow needs. This is going to depend on the size of your home, the number of people living in it, and your average usage, but to get an idea of what your flow needs might be you can reference the chart below:

ApplianceFlow Rate (GPM)
Bathroom Faucet
0.5 GPM
Kitchen Faucet
0.5 GPM
2.5 GPM
1.0 GPM
Clothes Washer
1.5 GPM

The maximum amount of flow you will ever need is if every fixture and appliance is running at once. This will almost never be the case, but it can give you a high-end estimate of your water pressure needs.

Type of Filter Media

Filter media is the material within a water treatment system that interacts with the water supply and removes contaminants. This could be as simple as a fine mesh to remove dirt and sediments, or it could be KDF or activated carbon which are known to be effective at removing heavy metals and organic compounds, respectively.

Knowing what’s in your water ahead of time by testing it will let you best choose the filter or combination of filters that will work best for your water. For example – if you have iron and manganese as well as herbicides and pesticides in your water, an AIO filter isn’t going to address all of those. You’d also need to add something like an activated carbon block filter.


Most filtration systems are simple enough nowadays that a competent homeowner can install their new filter themselves with minimal fuss. This saves the cost of needing a professional to install the system.

Most manufacturers make their user guides and manuals available on their websites, which means you can read up on how to install a filter before you buy it and even speak to their customer care teams if you have any questions. Some manufacturers like SpringWell even include how-to videos on their websites.

Maintaining Your System

Routine maintenance of a water filter system is especially important when dealing with an iron filter. Although maintenance is fairly straightforward, no two filters are alike and so they all have varying maintenance requirements.

When it comes to a water softener it can be harder to accurately predict ahead of time how often the pre-filters will need changing or how regularly you will need to top off the salt. The best advice for this is to do your research and select a softener that fits your home’s needs, and then monitor your salt consumption over a few weeks or a month.

This will allow you to gauge how quickly you are consuming salt and get into a routine of filling up when needed. Whether you’re using a filter, softener system, or both, it’s important to maintain your system as the manufacturer recommends to ensure that the warranty remains valid and to stave off the need for repairs.

Filter Replacements

Depending on the water filter you choose, you can expect to change the filters anywhere between 3 months and 20 years. Generally, you should expect correctly sized and properly fitted pre- or post-filters to have an average lifespan of 6-12 months.

You’ll also want to make sure you can easily access any replacement filters or media. Most manufacturers will have them for sale where you bought the original system, and you should check how long it takes to ship them so you can plan accordingly.

Iron Filter FAQ’s

These are some of the common questions other consumers have asked when looking for the best iron filter for well water:

Q: What are the most trusted iron filter brands?

A: Some of the most popular and trusted brands in iron and general water filtration are SpringWell, Pelican, AFW, iSpring, HomeMaster, and Aquasana.

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

A: A water softener removes total dissolved solids from the water, which includes minerals like calcium and magnesium and up to 1ppm of iron in most cases. This causes your water to be “softer”, which means it won’t form mineral scale.

An iron filter doesn’t work on minerals, but removes iron and potentially manganese, hydrogen sulfide, or other contaminants. It won’t reduce the hardness of your water, but some filters like the SoftPro Iron Master can remove iron up to 30ppm.

For more detailed information see our filter vs softener comparison here.

Q: What removes iron from well water?

A: There are three main filter types used to remove iron: air injection oxidization (AIO) media, kinetic degradation fluxion (KDF) media, and sediment filters for rust. Some water softeners use ion exchange systems that will also remove iron up to 1ppm.

Q: How much is an iron filter for well water?

A: This largely depends on the number of contaminants removed and the lifespan of the filter. The most expensive filter on our list, the Pelican WF4, is about $3,300 but it also removes more contaminants than the other filters and it has media that will last for about six years.

The iSpringWGB22BM, on the other hand, is only $398 – but it doesn’t work as well on iron and other contaminants and you have to replace the filters every 6-12 months.

Q: How long does an iron filter last?

A: Depending on the model, you can find iron filters like the SpringWell Well Filter that never need to be replaced and come with a lifetime warranty. On the other hand, the filters in models like the iSpring WGB22BM will need to be replaced every 6-12 months.



Having looked at all 7 of the best iron water filters, we can’t get away from the Springwell Whole House Iron Filter as the best filter for a well water supply.

It removes up to 7ppm of iron as well as manganese & sulfur, and it comes from Springwell – a market-leading brand in the filtration industry. If your home suffers from high iron levels in the water supply, you won’t go wrong with Springwell’s well filter.

A special mention also goes to the Softpro Iron Master, which has the largest iron filtration capacity at a very affordable price. Overall, we recommend Springwell first and then the Softpro or Pelican system for the best iron-specific filter.
