What is an Iron Filter?

Iron is a common contaminant in well water and is responsible for iron staining, yellowing, and increased iron build-up in your plumbing. 

Though iron is not necessarily dangerous, it can cause various problems, such as increased hardness or scale build-up in your pipes, accelerated corrosion in your fixtures and appliances, and a pungent or metallic taste in your water. 

Installing an iron filter is one of the best ways to improve the taste and odor of your well water. Iron filters are commonly used in homes with iron water sources, such as well water, or if the water tastes “metallic.”

These filters can remove up to 99.9% of iron and other minerals such as manganese, copper, and zinc, leaving it clear and sparkling. You can drink and use it without worrying that it will cause unpleasant side effects.

Many models available on the market allow you to either soften your water or reduce the amount of iron and other minerals that enter your water system. 

Iron filters are designed to remove iron from your water by passing it through a bed of iron-based resin. Iron-based substances, such as iron rust, bacteria, and algae, adhere to the resin and are collected, leaving your water clean and safe to drink. 

Iron filters are an easy way to improve your well water’s taste, odor, and clarity. They are great for reducing iron-based stains on fixtures and appliances, especially in areas with high iron concentrations in the water.

How To Choose The Best Iron Filter For Well Water?

Having hard water can be a real problem for many homeowners. Fortunately, an iron filter is a great way to combat the problem and make your well water look better, taste better, and be much safer for you to drink.

However, choosing the best iron filter for well water can be challenging with all the options available today. 

Here are a few factors that you should consider when selecting the best iron filter for well water: 

1. Iron Reduction 

Iron reduction measures how effectively the filter removes iron from water. 

Water filters commonly state iron reduction as a percent, with values ranging from 13-45%. Higher iron reduction values result in slightly softer water, while lower values are typically more noticeable to consumers.

2. Check Your Water Analysis: 

Before you buy, you must understand what contaminants might exist in your water—including any dissolved minerals like iron or sulfur that contribute to its hardness. 

Have your well tested by a local water department or an independent lab. This will help determine what type of filter is needed and its size and capacity.  

3. Consider Your Water Flow Rate 

Do you know how much water your household uses? 

If not, calculate it before moving forward with your purchase decision. Iron filters come in various sizes suited for specific flow rates, so make sure you buy one that can handle it without breaking down too soon. 

4. Measure Pressure Loss 

Pressure loss occurs when there’s too much resistance from the filter material (or sediment), which needs to be replaced or cleaned more often than expected. 

Therefore, choose a filter equipped with backwashing capabilities since these models reduce pressure loss by automatically leading trapped contaminates back into drain lines instead of having build-up on their filtering media components over time. 

5. Investigate the Filter Media Used 

Depending on the specific contamination they target, different types of systems use different types of filter; some are of carbon, while others use materials like iron oxide beads or manganese greensand granules (which can reduce iron levels below 0.2 parts per million). 

Hence, select one based on what kind of contaminants requires treatment most instead of getting confused over brand names because each has unique properties that offer excellent benefits in terms of utility and efficiency.  

6. Look for an Iron Filter with Multiple Stages of Filtration

When purchasing the best iron filter for well water, make sure that it has multiple stages of filtration, such as sediment pre-filtration and carbon post-filtration. 

Filter with several stages of filtration can ensure maximum protection against pollutants and maximize efficiency over time which means low maintenance costs over time as far as replacing media goes.

7. Consider Warranties Before Purchasing

Before purchasing any filtration system, it is crucial to carefully research the manufacturer’s warranties, as everyone’s circumstances, needs, and expectations change significantly based on personal parameters that are only sometimes known. 

Before making significant investments in the leisure, consider the current market also.

By considering these seven factors when looking for the best iron filter for well water, you can ensure that whatever choice you make will meet your needs and provide excellent performance for many years to come!

Different Types of Iron Filters

Various types of iron filters are available on the market, each designed to meet different needs and specifications. Understanding the different types of iron filters available is essential to help narrow down your options and make the best choice. 

1. Sediment Filters

Sediment filters are the most basic type of iron filter. They work by trapping iron particles that get into your water supply. Sediment filters are typically cheaper than other iron filters. Still, they are also susceptible to clogging and need to be cleaned more often. 

A sediment filter can trap various contaminants, including bacteria, chlorine, and lead, but it’s more effective at trapping iron. Sediment filters are typically the only type of iron filter you will see recommended for most homes. 

They are inexpensive and easy to install and can provide enough iron removal to prevent severe stains in your water supply. However, they offer less filtration than certain other types of filters.

2. Activated Carbon Filters

Activated carbon filters are the second most common type of iron filter. They work by filtering out the taste and smell of iron, providing a cleaner, less metallic taste in your water. The carbon in the filter adsorbs the iron particles in the water, leaving behind only pure H2O. 

Like sediment filters, activated carbon filters can remove a wide range of contaminants. But they are much more effective at removing iron than sediment filters. Even though they are more expensive than sediment filters, they can offer your water a better flavor and smell.

3. Iron Oxidation Filters

Iron oxidation filters are the most advanced type of iron filter. They work by reducing iron to a less-staining form of the metal called hydrated iron oxide. This can remove by the same water treatment systems that remove chlorine. 

Despite being a common water treatment method, chlorine induces adverse reactions in many people who are sensitive to it. 

Iron oxidation filters are expensive, but they are less likely to cause issues for people with allergies to iron. They are also more environmentally friendly than sediment and other filters by using less water and generating less waste.

4. Reverse Osmosis

Reverse osmosis (RO) is a type of ultra-filtration that purifies water by removing impurities using a semi-permeable membrane. 

The water enters the system at high pressure and then passes through a semi-permeable membrane to reduce the pressure. This membrane is made of a highly resistant material to osmosis, allowing water to pass through it but removing or reducing contaminants like iron. 

RO systems are the most expensive type of iron filter. They are also the most effective at removing iron from your water. 

RO systems are also difficult to install, requiring substantial water pressure and significant initial investment.

Advantages of Best Iron Filters for Well Water

People can use iron filters as standard water filtration solutions in homes and businesses. Iron filters have many advantages and can help keep your water clean and healthy while protecting your pipes from corrosion. Here are a few benefits of using an iron filter:

1. Remove Iron from Your Water Supply

The most obvious benefit of an iron filter is that it can remove even small amounts of iron from your water supply. 


While iron does not pose severe health risks, its presence in large quantities can cause staining to your clothing, dishes, and other fabrics. 

An iron filter will keep these unsightly stains away, leaving you with pristine drinking water free from any stains caused by excess iron. 

2.  Protect Your Plumbing System

Iron is one of the most damaging minerals in plumbing pipes and fixtures, as it can build up deposits inside the pipeline, which can block or restrict flow over time. 


By employing an iron filter, you can prevent these deposits from causing damage by having the media inside the filter trap them. This keeps your plumbing system operating effectively for longer than if left unchecked. 

 3. Prevent Bad Tasting Water 

Iron bacteria also tend to release metallic-like tastes into your water supply, which is unpleasant smelling and taste. 


Using an iron filter removes this bacteria and the corresponding taste, which helps improve the overall drinking quality of your home’s tap water.

4. No More Stains on Your Fabrics 

As mentioned earlier, washing clothes or linens in water with high iron levels can cause stains on the fibers. 


However, installing an iron filter considerably minimizes these traces, allowing you to keep your laundry in vibrant colors for longer!

 5. Lower Maintenance Costs

Compared to alternative filtration methods over time, iron filters are more cost-effective when maintained adequately as they require less ongoing maintenance costs. 


However, if these costs are not sufficiently monitored, measures like salt replenishment every few weeks or months, depending on usage, could cost you more in the long run.

6. Easy Installation 

The best thing about modern-day iron filters is that they are easy to install and maintain. 


All you need is an existing plumbing connection, tools like a pipe wrench, Teflon tape or sealant, PVC glue, and clamps to secure connections. 

Features of Best Iron Filter for Well Water

Iron filters are a great way to clean water from iron and other minerals that can cause health issues. They typically use in rural homes, farms, and campsites where iron from the ground is a problem. Here’s an overview of the features of iron filters, so you know what to look for when choosing one for your needs. 

1. Multi-Media Filtration

Multi-media filtration helps reduce rust, dirt, and other particles from your water. This type of filter has layers of various media, such as sand, zeolite, or charcoal, that help capture particles as the water passes through them. 


The different media also help add oxygen, absorb odors, and provide other benefits that regular filtration systems don’t offer. 

 2. Backwashable Iron Filters

Backwashable iron filters consist of an up-flow design with several layers of media which can clean easily using a backwash process, so they don’t have to replace now and then. 


Since you will not need new replacement filters all the time, this will also enable you to save money.

3. Rust Elimination Efficiency 

An important feature you should look for when getting an iron filter is its rust elimination efficiency rate which determines how well it cleans out rust particles and other contaminants from your drinking water supply. 

Higher quality rust elimination efficiency means more effective filtration results since fewer contaminants can pass through the system, giving your family cleaner drinking water at all times. 

7. Oxidation Technologies

Iron filters utilize a variety of chemical processes to oxidize (remove) the iron from water supplies. These include systems that use chlorine bleaching agents, peroxide-based solutions, catalytic reactions, and other chemical processes. 


The oxidative technology used depends on the type of filter chosen based on the amount of iron in the water supply.

8. Valves and Controls

A crucial component of an iron filter is its valves and controls that govern water intake into the device and expel filtered water away. 


The complexity of valves ranges from simple manual float valve/drain systems to complex electronic or digital valve controllers with several control choices that can significantly increase life span or performance times. 

When you are on the market for the best iron filter for well water, don’t forget to look for these features!
