Common Signs of Iron in Your Water

  • Stains: Look for reddish or brown stains on fixtures, sinks, and laundry.
  • Taste and Smell: A metallic taste or a distinct smell from your tap water.
  • Clogged Pipes: Frequent clogging or damage in pipes due to iron buildup.

Problems Caused by Iron in Water

Iron in water can lead to skin irritation, damage plumbing systems, stain laundry and fixtures, and affect the taste and smell of your water, making it unpleasant for drinking and cooking. All of these issues add up and diminish your quality of life.


Not only do you probably not want to see the red and brown stains in your toilets, but your home's plumbing wont be thanking you either. Iron deposits can build up inside of your pipes and water using appliances, like your dish washer and washing machine, and cause fairly significant damage over time. This can end up costing you a fortune to fix. The best way to deal with this problem is at its source!

Testing for Iron in Your Water

There are several ways to test your water at home. The quicker, more cost effective option is using a home test kit to confirm the presence and amount of iron in your water. These kits are user-friendly and provide quick, accurate results. You can easily purchase a home test kit at a local home improvement store or order one online. They come with easy instructions right on the back of their packaging.


If you don't feel comfortable testing your own water, or just want a more accurate set of results, you can always contact professionals through your local state certified water testing lab. This alternative can be more expensive, but they will be able to detect the exact issues you may have with your home's water, allowing you to properly address the problem at hand.

Determining the Right Iron Filter Size

The size of the iron filter you need depends on the iron concentration in your water and the size of your household. A higher concentration and larger household generally require a larger filter. We typically recommend most of our customers to go with a 2.5 cubic foot model as it can properly handle homes of all sizes and with any number of people living in them. Alternatively, if you have a smaller home with only 2 people living in it, a 1.5 cubic foot model may meet your needs.
