Note:
1. If using well water as the source, please make sure the feed water has been through a pre-filtration system, otherwise,
large particles in well water will clog the filter easily and shorten filter life.
2. The above form lists model numbers of only black filters. Please note that the white filter is different from the black
filter only in color. They have the same filter material and filtration capacity.
3. Actual filter life varies according to local water quality.
