I have the Typhoon 75gpd system. The DI has turned mostly orange, but not all the way. The pre-filter is also orange. Is this iron?

I bought a .5u spectrapure carbon filter & their Zetazorb prefilter. I now notice my unit has two carbon blocks. Is this one a good replacement for both, or do I need to put in two?

Also, I am getting a 3ppm tds when I first start the unit, but it falls to 0ppm after about 30 seconds. Do I need to replace the DI & RO filters?

I doubt you need to replace the RO for a while, and if you are getting 0 TDS out of the TDI after 30 seconds, I'd say you are fine, but you should have a spare DI filter on-hand to replace it when it's done.

The orange could just be sediment. I replace my pre-filter every six months or so, which might be more than necessary, but I don't like looking at discolored filters.
