Bottled water alternatives include options like reusable water bottles, water filtration systems, and tap water. Reusable water bottles can be made from materials such as stainless steel or BPA-free plastic, allowing users to refill them with water from various sources. Water filtration systems, including pitchers and faucet attachments, help improve the taste and quality of tap water by removing impurities. Another alternative is flavored water or infusions, which can be made by adding fruits, herbs, or vegetables to water for a refreshing taste. Additionally, some companies offer water delivery services that provide large containers of filtered water, reducing the need for single-use plastic bottles.
