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...
