I agree. ”It depends” seems like the right answer to me.
Having access to clean, tested spring water seems ideal. You’re a lucky one!
But for areas dealing with contaminated water (whether it’s PFAS, lead pipes like Flint Michigan, or literal shit and commercial chemical dumping from areas with lackluster water treatment, mostly outside the US) then “it depends” seems the right answer.
What’s the RO membrane rating? Does the system have UV? Charcoal? Remineralization? And do they perform the necessary maintenance? Seems like these are the critical factors about the system and might be found in someone’s home, might be at the stores, but it depends!
