What whole house Iron filter systems do you all have for water that has high levels of iron?  Needing to do something with my house and have been doing a lot of research online and have came across a few but there is such a wide range in prices.  I understand that filtering PPM is something to pay attention to but what else should I keep in mind.   Again, really looking for some suggestions on brands and what you like or dislike about them.   Thank you!
