Iron in Water

Water problems like hardness are the most encountered issues followed by iron concentration in well water.  Iron is a mineral present in rocks, soil, sediments, and groundwater.

Iron can seep into well water from rocks around, ores and other iron reactions underground.

Different types of iron require different methods of treatment.

Types of Iron in Well Water

The most important type of iron to understand before buying iron filters are the Ferrous and Ferric Iron.

Ferrous Iron

This type of iron can be seen by eyes because it’s clear. Water comes out of the faucet clear and without tasting its hard to detect iron presence.

This iron turns dark when exposed to the air as it reacts with oxygen to form a brown color.

Ferric Iron

This is the rusty water that comes out of the tap or from the well already discolored. It causes clogging of pipes and damage to water fixtures.

Organic Iron

Shallow wells and the ones exposed to surface water mostly contain this type of iron. It is formed from contact to naturally occurring acids or organic matter.

The removal of organic iron is harder than ferrous or ferric irons. The best option to remove organic iron is to use chemical oxidation and a mechanical filter.

Bacterial Iron

As the name suggests, bacteria organisms alter the iron to form sticky substances causing clogging and corrosion problems. Manganese presence increases the risk of well water getting contaminated with iron bacteria.

How to Remove Iron from Well Water

To efficiently remove iron from well water, it’s advisable to taste your water for the type of iron present. You can tell the presence of iron by the red/brown slimes on faucets, softners or tanks.

Types of Iron Removal Systems

Iron Filter

Used where the ferrous iron levels range from 7 to 15 mg/L. It can either use oxidizing media or pump ozone, air into the water to get rid of the ferrous iron.

Also, if this method is used the pH levels should be between 7 to 8.5 for better functionality.

Note: You should not use an iron filter when there is organic iron in the water because the iron filters cannot treat the bacteria in the water.

Water Softener

If the amounts of iron levels are low (3 to 5 mg/L), a water softener can be used to remove iron. Mostly water softeners are used to remove water hardness but in this case, it can help remove iron.

Note: water softener is not an efficient iron remover in well water. Also if the water contains different compounds of iron apart from ferrous, water softener shouldn’t be used.

Oxidizing Agent + Filter

This method is used in well water with high amounts of ferrous, over 10 mg/L. It makes use of oxidizing agents like Hydrogen and Chlorine to the water to destroy the iron compounds.

Air Injector + Filter

Iron is oxidized by injecting air and using a filter to strain the compounds out. It can remove up to 30 mg/L of ferrous.

Types Of Media In Iron Filters

Filter media are important for different iron removal depending on the iron levels and water pH.

Birm Filters

These filters remove iron and manganese compounds in groundwater. They act as a catalyst to create reactions between iron and oxygen.

The filter may require to be pre-oxidized when the oxygen levels in the water are low.

Birm filter is ideal in water with a pH level of 7 to 9, Iron levels of 15 mg/L. It doesn’t work where the water contains Chlorine.

Manganese Oxide Filters

You can use the Manganese filter to remove iron, Manganese and Hydrogen Sulfide in water with pH levels between 7 and 8. It works as a catalyst to facilitate oxidation which removes iron from the well water.

It also requires certain amounts of dissolved oxygen in the water for optimum results.

Greensand Filters

It is the most used and reliable chemical oxidant in iron filters with a high removal capability. Greensand filters can work even in high water flow rates and use moderate backwash.

The requirements for greensand filter are water pH of between 6.8 to 8.8, Iron levels of up to 15 ppm and the water should be free of Tannins.

Synthetic greensand can be used as an alternative which is lighter and requires less backwash.

Features of the best iron filters for well water

  • Minimum maintenance
  • Self-cleaning ability (backwash system)
  • No chemical additives
  • Handle whole house filtration

Things To Consider Before Buying The Best Iron Filter For Well Water


The capacity and right the size of the filter is an important factor to consider. The filtration system depends on the size of the house or the points of use in the house.

A larger family may require a higher capacity iron filter to be able to work effectively.

Water Flow

It’s great to know the GPM you use in the house to determine the iron filter to buy. The iron filter needs to release the same amount of water flow used in the house.

The most common water fixtures in the kitchen use the following GPMs;

Kitchen faucet – 1.8 to 3 GPM

Dishwasher – 1.5 to 3 GPM


An iron filter with easy installation would be great for people who prefer to install themselves. Installing the fixture by yourself can save costs on hiring a professional.

Check a product with detailed guides and instructions on how to install.

Filter Replacements

Ensure to pick a filter that is durable and doesn’t require regular replacements. If there is a need to change the filter, choosing a filter that is readily available in the market is ideal.

Also, the process of a replacement should be easy for individual installation without professional needs.

Water Softener

A water softener is an added advantage if provided together with the iron filter by the manufacturer.

Benefits Of Iron Filtration

  • Help eliminate the damage in water systems in the house
  • Remove rust and sulfur compounds
  • Pure water without metallic taste
  • Removal of sediments


I would recommend testing iron water through a professional for better results. With clear know-how of the type of iron present, choosing the best iron filter for well water becomes easy.

The iron filters in this guide consider different capacities, types of iron, water flow, and functionality.

Its time to get rid of iron and avoid costs from damaged water fixtures in the house by using one of the best iron filters for well water.
