What to Consider When Buying an Iron Water Filter

When considering purchasing an iron water filter for your well water, it is important to find the best filter for your needs. From maintenance costs to the ease of installation, there is a wide range of considerations that can be taken during the decision making process.

This buying guide will give you additional details on the types of filters you can install, features to look for, maintenance considerations, and more. By the time you finish reading the buying guide, you should have a good understanding of iron water filters for your well water.

Types of Filters

Different types of filters will remove the iron from your water in slightly different ways. Yes, the end result is the same, but all of the steps in between are important and you might find yourself preferring a certain type of filter.

The first type of filter is a stand-up tank style. Most water softeners are designed as a tank. Many now have a digital readout on the top of it so you can adjust the filter and know when the system needs maintenance.

A water softener uses what is called a cation exchange to reduce or remove calcium, magnesium, and iron from the water. Salt needs to be added to the water softener before it is used and maintained throughout the softener’s life.

When water flows into the softener and through the salt in the tank, the calcium, magnesium, and iron ions are essentially traded with the sodium ions. This removes the minerals from your water and prevents scaling and rusting. It can significantly elongate the life of your appliances.

If you would like to know more about the water softening process, check out this article. One of the only real disadvantages to water softening, besides paying to purchase salt to maintain the system, is it adds small amounts of salt into the water, so if you have a medical condition and are on a low or no-sodium diet, then a different filter might be a healthier choice.

Some systems are a two in one, meaning the water softener comes with a filter. If you are simply looking to reduce scale or rust coming from your water, the softener should be sufficient, but if you have other concerns, then getting a two in one should be considered.

Depending on what you need to be removed, even if you just want all of the iron out of your water, a two in one filter is a great option. Different filters will remove different contaminants so it is important to pay attention to what will be removed and make sure it fits your needs.

There are also stand up tank water filters that do not have the softener in them. These will not have salt that needs to be maintained, but likely another filter media or filter cartridge. It works the same as a water softener but the water will flow through a filter media instead of salt.

Another very common whole house water filter design is a 3-stage system. The water will flow through what looks like three separate canisters, each has a unique filter media that removes a certain type of contaminant. Together they combine to reduce or remove most major contaminants.

The 3-stage design is great if you are trying to remove hardness and other chemicals. Most systems such as this will remove herbicides, pesticides, heavy metals, industrial solvents, odor, cloudiness, bacteria, VOCs and many more in addition to iron, calcium, and magnesium.

If you are concerned your water is not just hard, in which a water softener would be sufficient, but actually has some form of contamination, then a 3-stage system is a very efficient and effective way to manage your water.

Types of Filter Media

A water softener will use salt as its filter media. As described above, when water is run through the water softener, the cations of magnesium, calcium, and iron are quite literally traded with the sodium ions. In this way, the elements that make your water hard are removed from the water.

Water softeners are very efficient at removing the elements that make your water hard but won’t remove anything else. So if you have hard water with no other concerns, then a water softener is the perfect solution.

water-filter-mediaThe 3-stage water filters usually use a combination of a sediment filter, a KDF media filter, and a carbon block. The sediment filter will reduce or remove any physical particles from the water such as sand dirt, dust, silt, rust, and scale.  
The KDF filter media is a very good media which is basically a catch-all at removing contaminants. Most KDF filters will remove up to 95% of the contaminant. It specifically removes heavy metals, radon, and chlorine.

The third stage is an activated carbon block. Some are made of coconut carbon and they are just as efficient as a normal carbon block would be. Carbon blocks will remove or reduce chlorine, benzene, radon, solvents, THM, and TCE.

One of the above filters uses a UV filter in conjunction with a water softener. The UV filter will remove living things from the water such as bacteria, fungi, viruses, including cryptosporidium and giardia. For more in-depth information on UV filters, check out this article.

Maintaining Your System

Maintaining your system is one of the biggest considerations that you will likely make when choosing your water filter, especially one that removes iron. Unfortunately, the lifespan of the filter media is dependent on how hard or contaminated your water is and how much water you use.

Maintaining-water-filterA home with four people and very hard or contaminated water will go through salt or filter cartridges a lot faster than a couple who just wants to get rid of the iron in their water. Manufacturers will usually give a range for the lifespan of the filter cartridges so knowing approximately where you fall in that range is important.

A water softener will simply need salt added to it as needed. Most of the other filters will have cartridges that need to be replaced. You can usually by the cartridges either individually or as a set. Depending on the filter, some of the cartridges might age differently.

Maintaining your system is obviously an added cost, but one that will keep you and your appliances healthy. It is important to consider this cost when purchasing your iron filter so the maintenance does not fall to the wayside.


Whether it is the initial cost of the filter or the cost to maintain it, the price of purchasing and maintaing a system such as the ones above can be pretty steep.

While it is important to do a cost analysis or at least consider what the total cost of powering and maintaining an iron filter will be for a year or set timespan, it is also important to remember the savings it could have for your home.

Iron can significantly reduce the lifespan of washers, dishwashers, and water heaters. Having a heavy iron presence in the water can also ruin your clothes and dishes or leave them with an odor.

In most cases, extending the life of clothes, appliances, and anything else the water comes in contact with can save more money and frustration than the cost of the unit and maintenance.


What is the difference between a water softener and a filter?

A water softener will reduce or remove calcium, magnesium, and iron, but not much else. It is very effective for hard water but if your water is also contaminated, a filter might be a better choice.

How often will I have to maintain my iron water filter?

It depends on the company, the design of the filter, your water consumption, and how hard or contaminated your water is. Some filter cartridges might only last a few months while other could work for up to five years.

Can I install the filter myself or do I need to hire someone?

If you have a basic understanding of tools and are good with YouTube, you should be able to install all of these filters yourself. If home maintenance is not your thing, then hiring a handyman or plumber could save you a lot of frustration.


If you have well water bringing and iron filter into your home can have a huge impact on your lifestyle. It will reduce rust and scale in your tubs, toilets, and sinks, and extend the life of your major appliances such as your washer, water heater, and dishwasher.

The best pick is the Home Master Whole House Three Stage Water Filtration System with Fine Sediment for its ease of installation and simple maintenance. It also very effectively removes or reduces not only iron but all major contaminants.

It is important to find the best iron filter for well water that best fits the needs of your house and your water. A filter like this can make your life so much easier and finding the right one might be the best purchase you make for your house.
