Best RO/DI filter replacements. 4 stage RO w/ spectra pure 2stg DI

Radioheadx14 · 01/18/2009, 09:21 PM

Well i just checked my TDS and it was between 2-4 so I need to replace all the filters. My RO membrane is fine but everything else is pretty old. I have well water so i don't know if i really need the carbon filter. My well water has no nitrates, phosphates etc.

What are the best replacements for the money?
Should I stick with what came in my 2 stage spectrapure DI?

and

Or is there something else that is just as good but cheaper?

Also, what size sediment filters should i get? I have 3 stages before the RO membrane. I was thinking 5 micron sediment, 1 micron sediment and mabye a 5 micron carbon.

Any help would be nice!
