When we decided to sell a low priced system there were many to choose from. Most of the cheap systems we would not like to become involved in as they will ultimately fail but this Aqua-Pro 960 system is made in Taiwan rather than China where most of the cheaper systems are made.
The 960 system comes standard with the plastic storage tank which we know over time has some problems so we ordered the system to be up-graded to have the 9 litre stainless steel tank, this cost us extra but it is a way better tank.
We also choose the 680 because it has fitted as standard the Dow Filmtec 50 gpd membrane, the Dow Filmtec is one of the two best membrane manufacturers in the world and because it is what is called a dry packed membrane, this is referring to the preservative in the membrane to stop bacterial attack prior to installation, dry pack membranes cycle in very quickly where as wet packed membranes can take up to 4 weeks, cheap units are usually fitted with cheaper wet packed membranes which also have a shorter service life.
The 680 are very easy to service and maintain and is compact.
This reverse osmosis system is Watermarked so no problem with plumber installation.
