No 1. Brio 500 Series Self-Cleaning Bottom-Load Water Cooler.
The Brio 500 Series is one of my favorite all-around picks because it’s bottom-loading, self-cleaning, and looks great with a modern stainless design. It gives you cold, room temp, and hot water, plus a low-bottle alert and Energy Star efficiency with separate switches to save power.
Pros
+Bottom-loading design fits 3- or 5-gallon bottles
+Self-cleaning function and low-maintenance use
+Dispenses cold, room temperature, and hot water
+Child safety lock on hot water
+Energy Star certified with individual feature switches
+Fairly quiet operation
+Low bottle indicator via digital display
Cons
-You still have to replace bottles when they run out
