If you must buy bottled water, choose store brands and save money. However, if you want to rack up serious savings, forget bottled water entirely and drink tap water — the quintessential generic. If you’re still unsure, get a good filter and run your tap water through it.
Even generic bottled water is a lot more expensive and not necessarily any safer than tap water. An estimated one-quarter or more of bottled water comes from a tap, according to the National Resources Defense Council. The nonprofit adds:
“It’s important to note that the federal government does not require bottled water to be safer than tap. In fact, just the opposite is true in many cases. Tap water in most big cities must be disinfected, filtered to remove pathogens, and tested for cryptosporidium and giardia viruses. Bottled water does not have to be.”
