Old, brand new RO membrane-still ok?

I guess I’m married to your wife’s sister:-) My wife starts complaining around 400.

I’ve done some light reading on the subject.
Most all reports are in milligrams per Liter, which it seems is the same as PPM?
Anyway US EPA and other sources recommend a level of between 30 and 60 with a max of 180.
Australia pretty much follows the same number, but says 200 is max, and then has an interesting comment, they say you can’t drink water salty enough to do harm?

Apparently some can taste very low levels of salt, and others cannot, and by a factor of close to 10 to 1, so very likely maybe one person says it’s too salty to drink, when you can’t even detect any salt at all.

However our TDS meters detect all dissolved minerals I believe, not just salt? So a reading of say 150, how much of that is salt?

Marina I am in in Jacksonville with the water filtered first through a 1micron carbon block filter before the tank and then through a Seagull filter, measures 215, which is higher than my Watermaker usually outputs, it makes very clean water in cooler water,less so in warmer.
I know filtering doesn’t remove anything dissolved, but maybe non dissolved solids could interfere with a TDS reading?
