Water has always been a vital part of human life. While we can go days without food, water is essential for survival. As we've advanced technologically, we've found more efficient ways to access clean water, with the water cooler becoming a common fixture in homes and offices. At Office H2O, we are proud to offer bottleless water coolers—modern, convenient, and effective solutions for staying hydrated.
But it wasn’t always this simple to get a cold glass of water. The journey to clean, accessible water has been long and complex, filled with innovations that shaped the way we drink today.
The earliest known records of water purification date back to 2000 B.C.E., with the Sanskrit text *Sushruta Samhita* describing methods like boiling, filtering through sand and gravel, or exposing water to sunlight. In Egypt, around 1500 B.C.E., sand filtration systems were even depicted on tomb walls. The Romans later took this a step further by building aqueducts to bring clean water into cities around 900 B.C.E. Meanwhile, the Greeks also used similar sand and gravel filters.
However, after the fall of the Roman Empire, water systems declined, leading to widespread contamination and diseases like cholera and typhoid. It wasn't until 1671 that sand filtration was revived by Italian physician Lucas Antonius Portius, who developed an improved system that helped make drinking water safer once again.
For centuries, sand filtration remained the main method of water purification. But in the 1840s, the Victorian era saw a shift as people began seeking chilled water. This led to the birth of the first water coolers—massive, heavy units that used ice and snow stored in ice houses to chill water in glass jugs. These early models laid the foundation for future advancements in water technology.
In 1911, Luther Haws invented the first drinking water faucet after witnessing children sharing water from a single tin cup. His design aimed to improve hygiene, but early fountains only provided room-temperature water, which often became a breeding ground for bacteria. After his father died from typhoid, Haws dedicated himself to finding a better solution—and he found it in water coolers. By 1938, he had developed an electric water cooler that significantly reduced disease outbreaks by keeping water at a safe temperature.
By the 1980s, plastic jugs replaced the heavy glass containers, making water coolers more practical and widely available. These units also became more stylish, blending well with modern interiors. They were equipped with air filtration systems to prevent contamination and even included heating elements for hot water. This period marked a major shift in both functionality and design.
Today, there are two main types of water coolers: bottled and bottleless. Bottled coolers use plastic jugs, which are an improvement over glass but still have their drawbacks. Bottleless coolers, like those offered by Office H2O, connect directly to the water supply, eliminating the need for bulky containers altogether.
Modern bottleless coolers come with advanced technologies like reverse osmosis, which removes impurities, chlorine, and harmful microorganisms. They are energy-efficient, eco-friendly, and provide a reliable source of clean, great-tasting water. From ancient sand filters to today’s high-tech systems, the evolution of water purification shows just how far we’ve come—but nothing compares to the convenience and cleanliness of a bottleless water cooler.
