3. Bottled water
According to the Mayo Clinic, bottled water and tap water generally are comparable in terms of safety.
In fact, more than 25% of bottled water comes directly from municipal water supplies. After treatment and purification, the water is packaged and sold at a steep markup.
If you’re concerned about the purity of your local tap water, invest in a faucet-mounted or under-sink filtration system, or a simple pitcher filter. Any of these options is far more convenient than lugging home cases of bottled water every week.
And by keeping a few reusable water bottles on hand, you can still stay hydrated on the go.
