Bottleless cooler systems require filters to remove organic material and sediment.
Most cooler systems have various stages for filtration. This allows the purest form of water to drink.
The Micron Filtration stage filters organic material and sediment with a particle size of 1 micron or larger including lead.
Carbon filters are used to remove odors, chlorine, and disagreeable tastes.
Water cooler filters should be changed once every year and it takes only a few minutes.
