📚 Methodology: How We Selected the Best Iron Filter Systems
Curious to learn how we shortlisted the iron removal water filtration systems for this guide? We’ve shared our methodology process, as well as the metrics we used to rank the filters, below.
Step 1: Researching All The Products Available
First, we searched for all the iron removal water filtration systems currently available for well water today. We made a list of these filters, including any important information we could find online, including their iron removal capabilities, their price, and their flow rates.
At this very first stage, we were able to cut our list significantly, removing the water filtration systems that (based on our comparison of their data) were far beneath the current industry standard.
Step 2: Reading Customer Reviews
Our next step was to visit marketplaces like Amazon and read customer reviews, which helped us to build our knowledge of a system’s performance – and how this compared to the manufacturer’s performance claims.
From reading customer feedback, we learned about the setbacks or negative features of certain filtration systems that the manufacturers obviously wouldn’t disclose. Customer reviews are honest and realistic, and we used this information to further cut our list of filters, removing those with repeatedly negative feedback.
Step 3: Conversations With Manufacturers
Next, we posed as regular customers and reached out to manufacturers to discuss their products in more detail. We did this for two reasons: to gather information about certain iron filters that wasn’t accessible online, and to determine the quality of the manufacturers’ customer service.
After discussing iron filters with manufacturers, we eliminated any filters that, based on the new information we’d gathered, were poorer-performing than their competitors. We also eliminated several filters sold by brands that provided particularly neglectful or unacceptable customer service.
Step 4: Personally Testing Our Shortlisted Filters
Finally, we bought and tested our shortlisted filters before comparing their performances and ranking them in this guide. We tested each filter for a minimum of 60 days before forming an overall opinion on its quality and value for money.
We used the following metrics to rank the filters featured on this list:
Iron Removal Ability: 30%
Most importantly, we considered a water filter’s abilities when it came to removing iron (the whole purpose of an iron removal filtration system), as well as other contaminants often found alongside iron, like manganese, sulfur, and sediment.
Budget is one of the most important influencing purchasing considerations for most people, so price was also an important metric when we compared and shortlisted the filters in this guide.
Flow Rate: 20%
Since most iron water filtration systems are installed at the POE, they shouldn’t significantly affect the water flow rate into your home. For that reason, flow rate was another metric we used to rank the filters in this guide.
Media Lifespan: 20%
A filter’s value for money is largely determined by its lifespan, so we prioritized iron filters with long lifespans when making this list.
Installation & Maintenance Requirements: 10%
We don’t know many people who wouldn’t prefer an iron removal system that they can install and maintain easily. When we produced this guide, installation and maintenance was the final important metric we considered.
🧾 Iron Water Filter Buyers Guide
You’ll find it much easier to settle on the best iron filter for well water in your home when you have a clear idea of exactly how to remove iron and what to look for in a good whole house iron filter.
This guide will answer any questions you may have about iron, including how it gets into water, the effects it can have on your home and health, how to remove it, and what makes a high-performing iron filter for well water.
🤔 How Does Iron Get Into Water?
The most common way for iron to get into well water is through the earth’s soil. When snow and heavy rain seep into this soil, they dissolve the iron minerals that the soil naturally contains.
If your well water is exposed to rusty or corroded plumbing, this is another common cause of iron contamination. Both your well’s casing and the pipes leading into your home may be made from iron, and when iron gets old, it rusts.
💡 Effects of Iron in Water
Both ferrous and ferric iron can cause a number of issues in your water, health-wise and home-wise.
Iron & Your Health
We need small amounts of iron to stay healthy, but drinking too much iron in well water can have the following effects:
Iron can cause skin conditions
Washing and showering in water containing iron can clog up your pores. This is known to cause acne breakouts and aggravate other skin conditions.
Iron can damage your organs
Ingesting high levels of well water iron can affect your body’s biological processes, affecting organs that store iron such as the heart and liver.
Iron & Your Home
Iron’s effects on your home are more noticeable than the invisible effects it may be having on your health. If you have high iron in your well water, you’ll notice:
Iron can cause plumbing issues
Iron from well water leaves deposits in the form of brown slime in your plumbing, which can cause clogging in pipes and fixtures and reduce water pressure.
Iron may stain your surfaces
The easiest way to check for iron is to see if you have the characteristic orange staining in your bathroom sink or tub. Iron is notorious for leaving stains on anything it touches. The toilet tank is one of the worst places for staining.
Iron leaves a metallic taste
High-iron water takes on an unpleasant metallic taste, and cooking with iron-contaminated water affects the flavors of foods.
✔️ What Are Iron Filters & Methods for Removing Iron from Well Water
Iron filters are water filters that can remove iron from water. Most iron filters can remove at least 3 PPM of iron, and the best iron filters can remove more than 10 PPM of the mineral.
How exactly do iron filters work? That depends on the type of iron filtration system used.
Air injection is the most thorough and cost-effective iron reduction solution.
When water enters into an air injection iron water filter, it’s sent through a pocket of compressed air, where oxygen is added. Water then passes through a filter media, which cseparates the oxidized iron from water.
Insoluble iron particles are converted into suspended particles and become trapped in the filter media. The system performs frequent backwashing cycles, washing away the insoluble iron and replenishing the air bubble.
Air injection iron filter systems are the most economical solution because they cost virtually nothing to maintain. There’s no need to replace the filter media because it lasts as long as the system itself. Oxygen, another important component in the system, doesn’t need to be replenished manually because it’s freely available in the compressed air pocket. And the backwashing process is mostly driven by your home’s water pressure, so the system, though plugged into electricity, contributes very little to your energy bills each year.
Most iron water filters that use air injection can remove iron and manganese, and many also remove hydrogen sulfide.
Chemical injection works in the same way as air injection to remove iron from water.
Measured amounts of chlorine or hydrogen peroxide are injected into the water, converting dissolved ferrous iron into easily removed ferric iron. This method of iron filtration also uses a media, like birm or manganese greensand, that traps the iron and flushes them away during backwashing.
Chemical injection is more expensive than air injection, and requires more maintenance (topping up the chemicals). Plus, not everyone feels comfortable adding chemicals to their water, so this method of iron filtration isn’t as popular as air injection.
A water softener, installed at your home’s point of entry, can be used to remove iron. Not all water softener systems remove iron from water, and those that can, only remove low levels of this mineral, when most of the iron is soluble (ferrous iron).
The water softening ion exchange process is a highly effective method of swapping out hard water minerals for sodium ions, using salt from the brine tank as a catalyst. However, it’s not quite as capable of iron reduction. That’s why it’s common to see water softener iron reduction systems combined with the best iron filters for well water, to remove the highest quantity of iron possible.
The prominent role of a water softener is to remove calcium and magnesium. Some water softeners come with a sediment filter, which removes larger contaminants like dirt particles, which are commonly found in well water.
Whole House Filters
Whole house filters for well water don’t tend to be specifically designed for iron removal, which means they have the benefit of also removing chemicals like chlorine, pesticides and herbicides; heavy metals like lead; sediment; VOCs, and more.
A whole house water filtration system typically includes a catalytic carbon block filter, an iron filter, a sediment filter, and a post-carbon cartridge. As a cartridge-based system, this type of filter can typically remove up to 3 PPM of iron particles.
🪨 The Types of Iron and Which Filters Remove Them
Now we know about the different iron filters available, we need to know what types of iron they can remove. Let’s look at the types of iron you’re likely to find in your water, and which filters remove them.
Ferrous Iron (Fe2+)
Ferrous iron, or dissolved iron, is a clear form of iron that doesn’t affect the color of water. Only when this iron is exposed to oxygen in the air does it start to turn red or orange.
Which filters can remove ferrous iron? Air or chemical injection is best to remove ferrous iron because this form of iron filtration converts dissolved iron into ferric iron before trapping it in a filter media.
Ferric Iron (Fe3+)
Ferric iron, or insoluble iron, is a gelatinous form of iron that is visible as a reddish or yellowish tinge in water. Ferric iron is one of the worst types of iron in water because it’s known to clog plumbing systems and appliances.
Which filters can remove iron in ferric form? The best filters for ferric iron reduction are air and chemical injection systems, as well as whole house water filters and water softeners (as long as the iron quantities are low). Because this form of iron is insoluble, it can be physically removed without having to be converted beforehand, which means more types of filters can remove it.
Bacterial iron, or iron bacteria, is a combination of iron and bacteria. Iron bacteria is a slimy substance that deposits brown or red biofilm on surfaces, causing major clogging issues. While iron bacteria isn’t harmful to human health, it does intensify an iron problem.
Which types of iron filter systems can remove iron bacteria? Chlorine injection with a chemical feed pump is the best solution for both iron and sulfur bacteria, preventing staining and eliminating sulfur’s rotten egg smell. If your bacterial iron problems are particularly severe, you may need to treat your water with shock chlorination before introducing any long-term methods of treatment.
How to Know What Type of Iron your Water Contains
In some cases, you may know that your water contains a certain type of iron. For instance, if your water has an orange of brown tinge, it likely contains insoluble iron. However, there are certain types of iron that you can’t see.
Testing your water is the best way to deduce what type of iron it contains. Use a laboratory to test for all three common types of iron.
📝 How to Select, Install, and Use a Water Filter for Iron Removal: Step by Step
Step 1: Test Your Water
Different types of iron filters remove different levels of iron, so you need to know how much iron your water contains before you start looking for a system. Test your water – either with an at-home test kit or a professional laboratory test – to determine the severity of your iron problem.
It’s also worth testing your water for other common contaminants, including those that often accompany iron, like manganese, bacteria, and sulfur. If you find out that your water contains these impurities, you can focus your search on a filter that removes them as well as iron.
Step 2: Choose your Preferred Filter Type
Would you prefer to spend more money on a low-maintenance, efficient iron removal solution, like chemical or air injection oxidation? Do you want to soften your water as well as remove low levels of iron? Or do you want to spend less money upfront on a cartridge-based system that needs more frequent maintenance?
Weigh up your options depending on your budget and your situation. There is no best solution for everyone, so make the right choice for your needs.
Step 3: Size the System Properly
Buying the wrong-sized whole house iron water filter for your home will affect your water pressure and flow rate. Iron filters that are too small will significantly decrease your water pressure, while filtration systems that are too big might damage your plumbing system or appliances.
You need your iron filtration system to meet your demands for water, even at your peak times of consumption, without being too much for your pipes and plumbing to take.
Most iron filters are designed for homes with 1-3 bathrooms, but if you’re unsure, contact the manufacturer for more information.
Step 4: Install your System
Once you’ve decided on and purchased an iron filter system, it’s time to install it.
Some people feel confident enough to install a filter themselves. But iron removal filters are whole house systems and can often be complex in design. Cartridge-based filters are the easiest to install, while chemical injection filters are the most complex.
If you can’t install a filter yourself, hire a plumber to do the job for you. It’ll cost around $200 extra, but you’ll know for sure that the filter is installed correctly.
Step 5: Check the System is Working
If you’ve bought an iron filter from a fair, trustworthy manufacturer, your filter should come with a money-back guarantee. This means that you can return the filter for a full refund if it doesn’t live up to your expectations – or doesn’t work at all.
During this guarantee period (which is usually about six weeks), evaluate the filter’s performance. Is it easy to use? Does it seem efficient? And, most importantly, is it working?
The best way to find out whether or not an iron filter is working is to test your water again. Test a sample of water directly from your tap, downstream of the filter. Your water’s new iron levels should be significantly lower than its original iron levels.
Step 6: Carry Out Required Maintenance
Finally, if you’re happy with your purchase, make sure to keep your iron filter in good shape throughout its lifespan.
Different types of filters have different lifespans and maintenance requirements. Some just require cleaning to prevent a buildup of iron bacteria. Others have cartridges that need to be replaced at least once per year.
💭 Key Considerations When Purchasing an Iron Filter for Well Water
It’s best to have an idea of what you need and what’s on offer before you go ahead and purchase an iron filter. The best iron filter for well water for your neighbor might not be the ideal solution for you. Being aware of the following considerations will help you to make a smart water filter decision for your home:
Water Quality & Other Contaminants
Before buying an iron filter for well water, test your water quality. Finding out exactly what’s in your water, and to what level, will help you to make smarter decisions when it comes to contaminant removal.
For instance, if you have a problem with chlorine in your water, you can consider buying an iron filter and carbon filter in one. Equally, if your water is hard but your iron levels aren’t too high, it may be best for you to buy a water softener with iron removing capabilities, which can soften water and remove iron at the same time. High-sediment and high-iron water will require a sediment pre-filter.
Finding out how much iron is in your water is important for choosing the right system for your needs. If you have more than 0.3 PPM of iron in your water, it’s enough to affect the quality of your drinking water. Too much iron can damage some filter types, so opt for a dedicated iron reduction system, like an air injection oxidizing system, if your iron levels are high.
Your well’s pH is another water quality factor to consider before installing an iron filter. Iron filters work best with a neutral water pH of between 7 and 8.5. If your pH is lower than this, your water might damage thr system, and the system won’t work effectively.
A filter’s capacity is a measure of how much filtered water it’s capable of producing on a minute-by-minute basis. The majority of filter systems are suitable for households up to 3 bedrooms. Some are available for homes with up to 6 bedrooms.
Filter capacity it affects the flow rate of water in your home, and the lifespan of the filter. Buying a filter with a small capacity may mean that your water flow isn’t strong enough to provide an adequate water supply to your entire home. If you enjoy power showers, make sure you buy a filter with a big enough capacity for your home.
The type of iron filter you opt for will mostly come down to your personal preferences (and the contaminants your water contains – see above).
Different filters require different levels of maintenance. A salt-based water softener, for instance, requires regular salt top-ups, while whole house filters need filter replacements an annual or bi-annual basis.
The longevity of an iron filter is usually a result of the type and quality of the filter you buy.
A whole house filter system has a lifespan of about 10 years, but you’ll need to change the individual filters every 6 months or so, which can be quite costly in the long run. Air injection or greensand filters tend to last around 4 to 8 years before you’ll need to replace the filter media.
Installation & Maintenance
No matter which iron water filtration system you choose, it’ll require installation at your home’s point of entry (POE) – the place where water comes into your home. Some iron filters can also be installed outside, between your home and your well.
Installation usually takes an hour or two and is relatively straightforward for someone with a low level of plumbing experience. However, as it involves cutting your water line and installing a bypass valve, not everyone will feel comfortable with the job. If you plan to call a plumber to install an iron filter for you, keep in mind that this will cost about $200.
Maintenance depends on which system you opt for. Whole home iron water filters have several stages of filtration, and each of these filters needs replacing at specific times (usually every 6-12 months).
Iron water filters that use a redox or oxidization media have a longer lifespan of around 5 to 10 years.. This type of water filter is still a great low-maintenance option if you don’t want the hassle of filter changes.
Water softener systems have a range of completely different maintenance requirements. The most important job is to add salt to the brine tank. You also need to clean out your softener once a year, and replace any worn parts, like o-rings.
Mo matter what water filter for iron you buy, it needs to have a warranty. A warranty is there for you if a filter is damaged as a result of a design flaw that’s out of your control.
Most warranties for a water filter for iron are split up on a part-by-part basis. In tank-based systems, the tanks have a 10-year warranty, and the control valve has a 5 to 7-year warranty. A typical water softener has a 10-year warranty on the tanks and a 1 to 3-year warranty on all other parts. A whole home water filter typically has a 10 to 12-year warranty for the system itself, not including the filter cartridges.
⚖️ Pros and Cons of Whole House Iron Filters
Let’s take a look at some of the biggest benefits and setbacks of using a whole house filtration system for eliminating iron.
No Iron Staining or Clogging
An iron water filter gets rid of the cause of orange or brown staining and clogging in your pipes, plumbing, and water-using appliances, so your water system will be protected going forward.
Improved Drinking Water Taste
By eliminating iron from your water, an iron well water filtration system significantly improves your drinking water’s taste – no more metallic flavor.
Additional Contaminants Removed
A typical iron filter – whether a single-tank system or a multi-stage unit consisting of several filter cartridges – can remove more than just soluble ferrous iron and insoluble ferric iron. Some whole house water filters can also remove bacteria, sediment, manganese and sulfur (commonly found with iron), while others use a catalytic carbon filter or carbon block filter to remove the likes of chlorine, VOCs, pesticides, and herbicides.
Depending on the type of iron filter you buy, maintenance should be minimal. Even cartridge filters only need their cartridges replaced once or twice a year.
Even if iron filters are a good value for money, they’re not cheap.
Difficult to Install
As whole house systems, iron filters are more complex to install than other types of water filters. However, for you to benefit from an iron-free water supply in your entire plumbing system, these systems need to be installed at your POE.
❔ Frequently Asked Questions
Can iron be filtered out of well water?
Yes, iron can be filtered out of well water. Not all filters remove iron, though – air and chemical injection, some sediment filters, and some water softener units are best for removing this mineral.
How do you deal with iron in your well water?
The best way to deal with iron is with a drinking water system installed at water’s point of entry into your home. This will filter the iron out of your entire water supply.
How do you filter rusty well water?
You can filter rusty well water with a sediment filter, an air or chemical injection system, and a water softener.
Is it expensive to buy an iron filter?
Yes. But the best types of iron filters have long lifespans and require minimal maintenance, so they’re still a great investment, and a good value for money.
Isn’t iron good for you?
In small amounts, yes. Iron is an essential nutrient for humans, being a component of hemoglobin, which transports oxygen around the body. But high levels of iron have been linked with adverse health effects, from damaged blood vessels to kidney and liver problems.
Should I call an expert to install my filter?
It depends on how handy you are. The majority of filter systems come with step-by-step installation instructions that guarantee success – if you follow them properly.
What should an iron filter remove?
A whole house filtration system for iron reduction should typically remove iron, manganese, and sometimes sulfur. It depends on what filter you opt for. The best iron filter will remove both ferrous and ferric iron, but this isn’t a guarantee.
Why bother with a filter when water bottles are cheaper?
If you can’t drink your well water because of high iron, manganese and sulfur content, the cheapest solution isn’t to keep buying water bottles. A filter for iron is a much more wallet-friendly solution in the long run. Calculate your average monthly water bottle spending cost, and you’ll see how quickly it adds up over the years.
When shouldn’t you use an iron filter?
You shouldn’t use an iron filter if your water supply has a high concentration of sediment or organic matter – unless you install a suitable pre-treatment system that will prevent damage to the iron removal system.
You also shouldn’t use an iron filter for the wrong purpose. For instance, if you want to remove ferric iron, most whole house iron filters will do the job, but ferrous iron requires a specific type of iron removal system.
