An important tool in reducing plastic waste, water bottle fillers deliver chilled, filtered water. They may be integrated within a refrigerator or water fountain or they may be independent units that are freestanding or wall-mounted. While they’re most common in workspaces, some municipalities now offer free outdoor public water bottle filling stations. Many units feature hands-free operation, anti-microbial protection, splash-free delivery, and advanced drainage systems to mitigate standing water.
