It’s really a shame how bad water has gotten in my lifetime. I only trust protecting my family with a RO because I no longer trust our government preventing corporations from poisoning our water or trust our government to safely filter and transport water to our household.
I installed a whole-house filter that was great when the EPA's recommended limit was 70 ppt, since mine drops it to < 10 ppt. Now that it's something on the order of ppq, I may have to add RO to at least the fridge, since that's where we get drinking water.
