Choosing an Iron Filter: What You Need to Know

If you're plagued by rusty stains, metallic tastes, and other issues related to high iron content in your water, an iron filtration system is exactly the thing you need. However, not all iron filters are created equal. This guide focuses on the must-have features for an effective iron filtration system.

What is an Iron Filter and How Does it Work?

Iron filtration systems are specialized filters designed to remove excess iron from your water supply. They operate by passing water through a tank filled with a filtering medium—often a specialized resin or material like Katalox Light, which captures iron particles. Once the iron is captured and oxidized, the filtration system flushes it out, leaving your water cleaner and more palatable. Whether you have well water or municipal water, an iron filtration system can improve water quality by eliminating the metallic taste and preventing reddish-brown staining in your fixtures and appliances.

Iron Removal Efficiency

When considering an iron filtration system, look for one that boasts high efficiency in removing both ferrous (clear-water) and ferric (red-water) iron. A system that can handle at least 7-10 ppm (parts per million) of iron is usually considered efficient.

Filter Media

The type of filter media determines how effective an iron filter is at trapping and removing iron particles. Katalox Light, for example, is renowned for its long-lasting performance and can remove up to 30 ppm of iron, along with other contaminants like sulfur and manganese. Fleck's Katalox Light Advanced Iron Filter is the best choice in the market and has left countless customers happy with its results.

Flow Rate and Capacity

Your household's water consumption plays a crucial role in determining the capacity of the iron filter you'll need. Here are some key aspects to consider:

  • Flow Rate: Ensure the system can handle the flow rate of your household (measured in gallons per minute).
  • Capacity: Check how many gallons the system can filter before the media needs replacement.
  • User Count: Make sure the system can adequately serve the number of people in your household.
  • Bathroom Count: The system should support the number of bathrooms in your home.

Installation and Maintenance

Check for a system that offers straightforward installation, possibly even DIY. Also, consider the maintenance it will require. Systems like the Katalox Light iron filter often require less frequent maintenance, which is a big plus.

Warranty and Certifications

Always opt for a system that comes with a solid warranty and necessary certifications like ANSI/NSF, to ensure the product meets standard quality and safety guidelines. A USA made product, created by a reputable company like Fleck, will go a long way in keeping your home's water properly filtered with minimal hassle.


Iron filtration is an essential part of ensuring your water's quality and safety. Consider factors like iron removal efficiency, filter media, flow rate, and capacity, as well as ease of installation and maintenance.
