In the chase for “designer” or “better” water, there’s some real concerns in systemically drinking too pure of water, i.e. little total dissolved solids. Pure water in these forms will leach metals and solids from the water transports, from containers, and from your body.

I’d encourage you to do a little research on RO water and the potential health impacts.

That said, I do own an RO system in my house. And use it selectively versus the simple whirlpool cartridge filter system built into my fridge.

I have a system from Costco. They sell various models but they seem to be from the Watts brand. These filters are all readily available from Amazon.
