There are many clear benefits to the ebac water coolers. It filters contaminants down to 0.5 microns–small enough to remove most visible particles, as well as Giardia and other parasites. The filter also removes chlorine, organic chemicals, pesticides, and colloids, and comes pre-packaged with one replacement filter and a bottle of germicide tablets in case you suspect viruses. Given its light weight, compactness, overall simplicity, and price, the water cooler is a great value for the weekender, or someone who needs a filter occasionally. But for longer trips or large parties, this water cooler would probably come up short.
