What Type of Iron Filter is Best for Low Levels of Iron?

Dear sir,

I have had my well water tested and have low levels of iron (1.2 ppm). No manganese, and the pH of my water is neutral. I don’t have problems with odor, just rust staining on the sinks and clothes. What do you recommend? I am not sure of my well pumps flow rate, but I have a LOT of water pressure and flow. My well pump is a 1.5 HP and my well has a lot of water.

Mr. Rodriguez,

There are two main options to consider for iron removal.  Our Pro-OX iron filter would do the best job of oxidizing and filtering out the iron to prevent rust-colored staining.  Or, as a more economical alternative, we offer our Birm iron filter systems as well.  The Pro-OX iron filter is a much higher-quality media that won’t easily break down the way Birm does.  

Pro-OX is heavier and denser than Birm, but it lasts much longer (usually between 7 to 10 years, compared to around 4 or 5 years maximum for Birm) and can handle higher amounts of iron.  The Pro-OX system is more expensive than Birm, but it is a much higher quality iron filter. 

Here is a diagram showing how the iron filter systems are set up:
