In these rare instances, we recommend this carbon block filter. While this filter is not as robust as the Microbiological Filter, it will last 12 months under harsh water conditions.
IMPORTANT: only order this filter if your serial number is prior to 4116297. If your serial number is between 4116297 and 4134313, please call us toll free at (800) 222-7820. This filter replaces filter number 7009931.
