Although the Below Sink Drinking Water Filter Systems shown here involve more work to install than our counter top models, they offer a couple of advantages. For example, the filter and hoses are hidden from view beneath the sink, which frees up counter space. Also, the filtered water is dispensed from a separate faucet, which means no diverter valve nor additional hoses are needed. And you can get pure filtered water whenever you need it without involving you sink faucet. Otherwise, both counter top and below sink systems provide same high level performance and NSF/ANSI certified standards.
