Time to replace my present unit and need some advice from the pros. My old reverse osmosis unit is from sears, just a plain 3 stage unit. We live in the country so we have our own well. I have an iron removal unit and a water softener unit in front of the RO unit. Am considering a RO with UV. What do you recommend.

I recently replaced my old RO unit with this one and it is fantastic. The 6th stage adds some minerals back and really improves the taste.

Here is the version with the UV in you need that...

I decided on the RCC7AK-UV unit. It is installed and works great. Don't know what to do with the old unit. Just needs new filters and good as new. Only reason I replaced it was for the UV and now I find I could have added the UV to my old unit. Oh well I am happy with the new unit. Am considering placing the storage tank in a small freezer (about 50 degrees) in the basement so I will have cold water instantly. Thanks LBTRS.
