TDS creep inside the membrane house

I know that if water sits long enough within the RO housing, the TDS will shoot up as high as 100ppm, but my main concern is, are those PPM mainly dissolved various salts? like, no bacteria, or organic compound can be passed through the membrane, right? and so it is still better to drink the initial 1 minute high ppm water than straight tap water and it still filtered out those harmful organic compound and bacteria, right?



So in order further reducing the intake of those 100ppm salts, adding a DI unit can solve the problem, right?



Can someone clarify?
