Exactly. One thing I’ve learned from areas with unsafe drinking water is the beauty of stores dedicated to providing purified water (delivery an added bonus). Going back to the US and drinking “safe” tap water has always been pretty gross after that, even in houses with some filtration systems.
A home-based RO system would be nice, but I’ve always wondered if the ones people usually get (<$500) can compete with the quality of the commercial suppliers/stores that you typically see in other countries. Likewise for the small fill stations common on the outside of US grocery stores. Are all these systems truly of similar quality? I have a hard time trusting those tiny little under-sink setups and the unattended outdoor water fills.
