Family of three here and we're replacing our old RO purifier. I've noticed quite a few models now offer copper water, and I'm wondering whether it's actually useful or just another feature added to make the purifier more expensive.
If you've been using a copper RO for a while, have you noticed any practical difference? Also, is there any reason to specifically choose copper when buying an RO?
