The SoftPro Iron Master AIO is a one-tank air injection iron filter with Katalox Light, rated to 30 ppm of iron and 7 ppm of manganese, in three sizes at $1,517 to $1,897. I put it beside our Fleck 2510 AIO size by size: the backwash flow each needs, the sulfur rating, warranty and returns, what ships in each box, and where the SoftPro is the better buy.
No annual maintenance. An air injection oxidation (AIO) iron filter cleans itself. It backwashes on its own, a sediment filter ahead of it protects the valve, and every 6 to 8 years the Katalox Light media is replaced. Here is the schedule, how to start a backwash on either valve, what is normal after one, and how the media change goes.
Katalox Light is an iron filter media, made by Watch Water, that takes iron, manganese and the rotten egg smell out of well water without chemicals. Our filters with it are rated to 30 ppm iron, 15 ppm manganese and 10 ppm hydrogen sulfide. It needs a valve with a strong backwash, works best near pH 8 and lasts about 6 to 8 years. Here is what it is made of, how much your filter takes, how to replace it, and whether it will work in a tank you already have.
