Berkey Filters prioritize the safety and health of its consumers, which is why all the plastics used in the filtration process are BPA-free and non-toxic. This means that there are no harmful chemicals that can leach into your water and cause any health concerns. The water passing through the filter and then through the tap will not come in contact with any harmful plastics. The option of a stainless steel tap is available for those who prefer metal components in their filtration system.
