> I was thinking of putting a Reverse Osmosis filter in my Kitchen. Would RO water just leach this chemical out then from plastic containers? Since the RO water is pretty pure. All the RO units I've seen are made of plastic.

High density polyethylene is made without plasticizers.

That's hydrogen sulfide. Humans are _highly_ sensitive to it, but in general it's safe in itself.

I don't know what the standard way to do it is, but, surely it's not too complicated to add some tasty minerals back in.

I make a water sweetener with a variety of electrolytes and sugar, and regularly add a tiny bit to my water bottle. Placebo or no, I love it.

One can also absorb chemicals through the skin (it is the largest exposed organ infact), so I've been thinking of getting a shower or whole-house filter. Definitely upgrade from the Brita though. Brita's aren't very effective at filtering PFAS last I read.

But to answer your question, I'd speculate that the filtered water from the RO filter would be superior to anything coming out of your tap, even if it had phthalates in the filter. You also have to account for PFAS, heavy metals, medicines people excrete back into the water supply, and many many other things...
