Unneeded features: Are membrane-flushing and built-in TDS meters really necessary?

No, they are not necessary. They are useless features added mainly to help sell the products. Membrane flushing is an old technology used only for commercial RO membranes these days.

Most residential RO membranes now utilize new technologies that require no flushing. The most dangerous is the "auto flush" type, because it actually "reduces" the life of your small home membrane by flushing it constantly, even when there is no need to do so. Some suppliers claim that flushing is needed for their membranes to last 2-4 years.

Yet our advanced membranes, without the hassle of flushing, can last up to 8 years if you just change your pre-filters regularly. The built-in TDS meter on the RO system is also not a good idea. It actually misleads customers because the TDS meter does not indicate when it's time to change the filters.

It lights up only when your TDS is very high —after your membrane is damaged! Those simple built-in meters do not show the actual TDS reading, they only show "good" ... more.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
