Oh. Sure. That will always be so cumbersome we don't have to worry about it. That would be a huge RO system. They don't have a lot of throughput so you'd need a big storage tank or a very large set of filters and a pump I'd think. I'm not at all concerned whole home RO will every be common.

Only places I’ve seen it are places like China where people just don’t trust the water at all.

A friend of mine in Brazil had a whole home filtration system (not RO) that even had a UV sterilizer at the end!
