Well Water Iron Filter

Iron Problems With Your Home's Water?

An iron problem is characterized by the red-brown staining of bathroom fixtures and laundry. In well water, iron usually occurs in its ferrous state.

The water is clear when drawn but once exposed to air the iron changes into a ferric (oxidized) state. The water turns red and forms insoluble “rust” particles.

Staining can be caused by as little as 0.3 milligrams per liter (mg/L).

Depending on the iron concentration there are several solutions to this aggravating water problem.

Proper Iron Filter Sizing

Measure your well pump flow rate

The larger the iron filter and the type of media being used dictates what pump size is required.

Some iron filters can take up to 20 GPM to backwash.

If you install an iron filter that can’t be backwashed properly the media well get fouled and the system will not perform as it should.

A simple test with a basic 5 gallon bucket will measure your effective well pump approximate gallon per minute.


Check your well pump's effective flow rate...  Easy as 1, 2, 3...

Minimum Water Flow Rate Required:

The size of an iron filter or pH neutralizer system is dependent on the flow rate from your well pump. 

Please check your flow rate to select the properly sized system.

Do not select a system that requires a higher flow rate. 

🛎️ Priority - Know your Pump Flow Rate

Your well pump GPM is the #1 Sizing Factor

Remember that the size of the home and the number of bathrooms come second when sizing iron filters.

This is due to your well pump ability. You can only use what your pump will give you.

For Example:
If you have three showers running at the same time you need 7.5 GPM to operate them all and still have good pressure.

If your well pump only gives you 6 GPM you will not be able to operate all those shower heads at the same time and have good pressure.

So if your well pump does 6 GPM you are limited to an iron filter that requires less then 6 GPM to backwash.

Most iron filters that fit this criteria have flow rates of 4 to 7 GPM.

Other Iron Filter Systems

Greensand Iron Filters

Iron, Sulfur, & Manganese Removal.

Greensand has a thin coating of manganese oxide in conjunction with potassium permanganate. This will oxidize iron, sulfur, & manganese for better removal.

This system has low flow rate abilities in comparison to other systems offered and requires an oxidizer to oxidize iron, sulfur, and manganese so the greensand media can remove it.

This system was one of the original iron filters on the market dating back to the early 1970s.

What Filter Size? 

In general, match your effective well pump flow rate to the backwash requirements to select the appropriate filter size.

Typical size is the 1.5 CUFT size, if your well pump can accommodate. An option is that you can also select a smaller size, if higher flow rates are not required.

NOTE: Minimum Well Pump Flow Rates Are Required. See Specs below or try our WISDOM tool.
