Compact Stage 3 Replacement
Stage Three: 1 micron sediment pre-filter removing 99% T.D.S (Total Dissolve Solids) rejection performance
NOTE: This is not the normal sized replacement filter, it is strictly for our COMPACT unit and not the TRADITIONAL
Normal TRADITIONAL replacement cartridges are 10" or 254mm
Our COMPACT unit uses: 238mm or 9.3 "
Beware some Reverse Osmosis websites and replacement filter websites report inaccurately the sizing of their filter replacement cartridges.
If you have the free standing 45cm high traditional unit, then that uses the 10" cartridges, only PHATWATER manufacture the COMPACT unit thus using the smaller 9.3" replacements.
