Availability: In stock



The OmniFilter CB3-SS6-06 water filter is a single-stage under-sink water filter for use with Omni's undersink water filtration systems. The OmniFilter CB3-SS6-06 is also compatible with any brand of water filtration system that uses 9 3/4 inch x 2 1/2 inch filters. This filter has been redesigned with larger end caps, and as a result, may not fit older OmniFilter housings, including: OB3, SFM2, SFM2 Series A, CBF1, CBF3, CBF3 Series A, CBF20, OT32 Series A, OT2/U600, UC2/U500-OmniDeluxe, OT5/U700, SMF-5/U400 OmniSuper, RO2000/RO2000TDS (Original with blue prefilter sumps).
  • OmniFilter recently changed the CB3 to a larger size which may not fit old OmniFilter systems
  • The filter is now open at both ends and the rubber gaskets are thicker
  • If the thicker gaskets make it difficult to close your filter housing, please replace them with the thinner gaskets from your old filter
  • Made in the U.S.A.
  • Genuine OEM Product

The best carbon block filter out there Review by TFD
We use it to filter well water for drinking coffee and icemaking purposes. This filter is totally worth the expense. It last a long time and the water tastes and looks totally perfect. We have had this filter system for about 12 years now and it has never broken down. (Posted on 3/24/11)
