The water coolers are plumbed into a water source then filtered to half a micron utilizing a three filtration cartridges which take out all dirt, sand, bad tastes and odors, chlorine and other chemicals. These plumbed in water systems produce the same quality of water as the water bottle systems without the hassle of storing full or empty water bottles.
The water filtration cartridges are changed every six months at no charge and units are rady to use within one hour of the filter change.
