Buyer’s Guide for Iron Well Water Filters

Iron is a common contaminant found in well water. While it’s generally not harmful to your health, it can give your water a nasty, rusty taste and clog your home’s plumbing system with a scaly build-up. 

If you’ve ever gotten rust stains on your favorite shirt, you know those bad boys don’t budge.

There are lots of iron water filters on the market. While having a variety is a good thing, trying to choose one can be confusing, especially if you don’t know what you should be looking for. 

Let’s take a look at the factors you should consider if you want to nail it on the first purchase.

Water Flow Rate

Iron filters will have a water flow rating indicated in terms of gallons per minute. This tells you the amount of water you can expect to have running in your house in one minute. 

When you’re looking for a well water iron filter, consider the water flow. The more water you need to run your household on, the higher the filter’s flow rate should be.

Your Water Source

When looking for a water filter, your water source should always guide your choice. If you get your water from the local municipality, the contaminants to expect are chlorine, chemical contaminants, and a little bit of sediment. 

If you’re getting your water from a private well, you can expect sediment, iron, heavy metals, and more.

The assumption is that, since city water is usually treated before it gets to your house, you can expect fewer contaminants. The only way to be certain of the contaminants in your water is to get your water tested.


Some filters need replacing more often than others. Most of them will have an indicated replacement period, after which you should replace the filter.

Flushable or cleanable filters will usually have a longer lifespan because you can flush out their accumulated contaminants.

Before buying an iron filter, find out how long you can use it before you have to replace it.


Some filters are easy to install without the help of a professional plumber. Others will require you to get an expert for the installation. 

If you don’t want to spend hundreds of dollars on the installation, find a filter that you can easily install yourself – without compromising on functionality.

Frequently Asked Questions About Iron Water Filters

How do I know when to replace the filter?

As mentioned earlier, most filters will have an indicated replacement period, after which you should change them. Depending on the number of contaminants in your water, however, you might need to change the filter earlier than indicated.

The best sign that it’s time to change the filter is a drop in the water pressure. This indicates that the filter is getting too clogged to allow water to pass through as it should.

What kind of filter should I get?

This is determined by the contaminants you have in your water supply and the level of contamination. If you’re getting water from a well, you might need to get a multi-stage filtration system since the water hasn’t had any prior treatment.

Municipal water, on the other hand, is usually treated, and there might not be as many contaminants in the water. A simple filtration system might do the trick in that case.

Is iron in drinking water harmful?

No, iron is not harmful in drinking water, but it can give your drinking water an unpleasant rusty taste and color. The scale build-up in your plumbing system and the stains on your clothes can be bigger causes for concern.


If you’re using water from a well, an iron filter is likely to be an inevitable necessity. In this guide, we’ve put together a list of the 5 best iron filters you’ll find on the market. 

Any of these options is bound to make a great choice, but remember to keep your specific contaminants in mind before you make any commitments.

We hope you’re now able to find the best iron filter for well water! Good luck!
