Regarding a post from long ago (Google is great). I use a greensand filter followed by a softener which uses salt. I am wondering (more now than ever)
- if I need the greensand filter considering what Gary wrote long ago.
- At what level of iron will a softener be able to handle the iron removal?
- "Less expense" also naturally caught my eye.
I never did like the idea of potassium permanganate especially since during last year's servicing when the technician sent the solution through our water heater -- I spent the better part of the day running (read: wasting) hot water until it came clear again. Please enlighten me and point me in knowledgeable directions (more reading and research). Thank you.
David.
P.S. It was an advert for Kinetico whole-house filtration that started me on this tonight. It seems that, if true, the Kinetico system would be much less expensive than the greensand (and yearly maintenance), softener (with its several-bags-of-salt/yearly appetite), and carbon filter block (at the sink) system we use.

Frankly, IMO and that of many others, the 'non electric' is nothing more than a gimmick and comes with the short comings you have admitted; their inability to handle iron which you state you have to use manganese greensand to eliminate. You must not do much water quality improvement if you're still using greensand. There are other much better means at less expense and they don't use a hazardous material to regenerate with such as potassium permanganate.
