What are Whole House Water Filters for Iron?

A whole house iron filter for well water filter refers to a system designed to remove chemicals from the main water supply. This can include potential traces of iron. 

Iron is noted for being an unwanted contaminant in larger quantities. In general, drinking water holds 10 mg per liter and any amount higher than this can create significant challenges such as metallic-tasting water or stains. It can also lead to iron deposits collecting in the pipes and causing damage.

To determine an iron problem in the water supply, it’s best to find the source. In many cases, it has to do with corrosion in the plumbing system (pipes). Plumbing can have many types of problems, and some piping is even inherently defective like polybutylene.

Iron can also come straight from the main water supply if it’s spoiled. As a result, property owners are recommended to test their water for iron bacteria, alkalinity, and hardness before buying the best whole house water filter.

A traditional whole house iron filter for well water connects straight to the main water line and helps remove sediment, iron, chloramine, or chlorine.

The iron is removed with a specialized whole house iron filter. The filter uses manganese dioxide media to manage the iron. These filters can convert approximately 15 mg/L of iron in the water before removing it using a traditional sediment filter. All of this is done using one system, which makes it easier for property owners to set up.

The idea is to clean the water and make sure it’s ready for human use or consumption. Otherwise, the water can be hard, filled with debris, and infected. This is why whole house water filters play an important role in the safety of those living inside. 

Since it’s a “whole house” filter, all of the water is filtered through the system. This includes water going to the dishwasher, kitchen sink, bathroom, or washing machine. 

When the system is turned on, it immediately begins filtering out the contaminants (i.e. iron, chlorine). It’s important to note, each property has unique demands when it comes to finding the right iron filter. It often depends on the amount of water needing to be filtered, the property’s size, and what is being filtered out.

How to Pick the Best Whole House Water Filter for Iron?

  1. Local Contaminants and Disinfectants

Begin by looking at the city’s water and what’s coming into your house.

Start examining the different types of chemicals found in the local water supply, how they impact your life, and what type of filter will make a real difference.This makes it easier to find a legitimate whole house water filter for iron. 

If you’re aware of higher iron levels in the water, it’s important to go for a filter that’s specifically designed to remove iron. If the system can’t handle contaminants in your city’s water supply, this may take away from its efficiency.

A good example of something that wouldn’t work is a filter that removes chlorine when the water supply is filled with chloramines.

To better understand what’s in your city’s water, feel free to reach out and visit the local government website for more information. In most cases, there’s a specialized water department in place to help with these questions. They will be more than happy to shed light on what’s in the water.

  1. Flow Rate

The flow rate is just as important as other features of a water filter system. This specific detail refers to the filter’s “flow,” (gallons per minute). By knowing this number, you can determine how much water is available at any given moment.

Imagine using your dishwasher, washing machine, and shower at the same time. Can the water filter handle it? To answer this question, you need a higher flow rate to keep everything working.

According to recent studies, the average toilet has a flow rate of 5, while showerheads come in at a flow rate of 2.5+.

Keep this information in mind while buying a whole house filter system. Add up the different numbers and make sure the system’s flow rate is higher than your house’s requirements. In general, anything less than 10 isn’t going to work well.

  1. Ability to Remove Iron

This is one of the most important requirements when it comes to water that’s high in iron.

Check to see whether or not the water filter is capable of handling iron. Can it handle large amounts of iron coming through the main supply? Can it consistently remove the iron without breaking down?

These are essential questions when the main focus is on filtering out iron. Don’t get mesmerized by other chemicals or contaminants because your water supply is likely high in iron.

While the market has great all-around water filters, it’s still important to begin with the basics. Look at something that can manage iron and then move forward from there. Otherwise, you could end up with something that doesn’t work well with your water supply.

  1. Port Size

The port size is often ignored when it shouldn’t be. In general, the best whole house water filter should have a port size that’s 1”. 

The reason to look at the port size is to make sure nothing gets in the way of the water flowing through your filter. It makes sure the water gets from point A to point B without slowing down or getting trapped in the pipes.

  1. Filter Life 

How long is the filter going to last once it’s in use?

This is an essential feature to look into because certain filters age rapidly. You want something that’s efficient, easy to install, and can handle iron without needing regular maintenance.

For most cases, a water filter should last for at least 100,000+ gallons with some going up to 150,000 gallons. Of course, the numbers can vary but it’s best to look at carbon filters as they known to last longer and deliver better results.

As long as the filter lasts 100,000 gallons, the replacements won’t become an ongoing problem.

  1. Filter Size 

The filter’s size is crucial when figuring out how often it will need maintenance. A larger filter can handle more and won’t break down as easily. It also allows more water to go through the system. For most homes, it’s okay to go with a filter that is around 4.5” x 20”.

This offers a respectable flow rate and comes with the right port size too.

How are Whole House Water Filters Different From Other Filters?

A whole house iron filter for well water can vary. The different types are based on specific contaminants in the water, what’s being filtered, and how the filter is attached.

For example, tap water is regarded as being filled with contaminants that can be bad for the human body. This means it’s important to go with a filter that can handle those particular contaminants including iron. The best iron filter for well water needs to generally come in a “3 stage” setup to make sure it covers the entire house and filters everything consistently.

The tap water also includes disinfectants to control potential outbreaks such as diphtheria and typhoid. The right 3-stage whole house water filter assists with removing those disinfectants and making it easier to wash your clothes.

However, there’s a secondary option available on the open market, which is designed along a two-stage setup. This refers to only removing sediment and carbon from the water. The filter can be attached to different supply sources but it’s sometimes not effective in getting rid of everything in the water.

Since it’s possible to deal with contaminants such as chlorine, iron, hydrogen sulfide, it becomes important to find a reasonable solution that’s easy to install and works well.

Where to Buy the Best Whole House Water Filter for Iron?

To purchase a world-class, reputable whole house water filter for iron removal, it’s best to buy on Amazon.

This is a reputable online retailer that has some of the world’s finest filters all in one place. Take the opportunity to dig through the various options, choose the right one for your home, and move forward with something worthwhile.
