Spectropure has been around for a very long time, I had some of their original systems back in the early 2000s when they were $500 for pretty much the same system. Yes they make excellent systems but in this day RO systems really have become very common place and there's no reason to spend extra money on a Spectrapure. One could get one of these cheaper systems and just buy their filters when it gets time to replace. Of course just my opinion.

No big difference. Test the TDS, let the data talk.

Quote from Jackie8z :
I have a countertop expresswater at home to supply both hot and cold water. It is painful to refill and drain the water in tank (I put a pump but still extra work), any good under sink system with hot water?? My wife wants hot water function.
this reminds me of the people that put a float valve and hook up the r/o line to their keurig machines, lol. you can try something like this:

Quote from franco77 :
I have been using an RO system for over 20 years. But the membrane for the final filter is very expensive, around $60+, then add the other rope filters it gets pricey. This setup would not be much more than my filter replacement package, and I get a new tank!! Hmm
i dont know what system filters you are buying but the standard 10 inch filters are way cheaper, although i will agree the most expensive filter is the R/O membrane itself but its only like $35 for a good brand one. you can buy in bulk standard 10 inch sedemint filters for cheap on amazon along with the carbon filters.
