The HIP Triple water filter systems (known as HIP3 or HIP320) are available as an under sink drinking water system that uses Doulton ceramic filter technology. To ensure that the filter system is working at optimum performance, flow rate, and contaminate removal it is recommended to replace the ceramic filter at least once a year. These systems originally came with the Ultracarb ceramic filter candle and several choices for the second and third filters. You can upgrade your Ultracarb to the CeraCarb ceramic filter candle for increased filter life without compromising your filtration level and continue to use the second and third filter of your choice.
