Product Details

2pcs Compatible / Replacement OmniFilter CB3 Undersink Carbon Filter (Series B)

Not Original Omnifilter but will work and Fit perfect

Note: There are two versions of the CB3 filter. Those built after 2014 are labeled Series B, and those built before 2014 are labeled Series A. The diameter of the CB3 Series B (as shown on this product page) is .15" larger than Series A filters.

The CB3 Series B may not fit some older Omnifilter housings. We have complied the below list of Omnifilter housings that the CB3 Series B filter will no longer work with. In the past you may have bought the CB3 and it fit one of the listed filter housings but this will no longer work. If you are looking for a filter that is the same size as the CB3 Series A, we recommend the OmniFilter GAC1 Undersink Carbon Water Filter. Keep in mind that the GAC1 has a 20 micron rating compared to the CB3 Series A micron rating of .5.

The current CB3 Series B is NOT compatible with the following housings:

OB3

SFM2, SFM2 Series A

CBF1

CBF3, CBF3 Series A

CBF20

OT32 Series A

OT2/U600

UC2/U500-OmniDeluxe

OT5/U700

SMF-5/U400 OmiSuper

RO2000/RO2000TDS

If you want to continue using CB3 filters with the .5 micron rating you should consider upgrading to the OmniFilter CBF3 Undersink Filter System (Series B). As a general rule, filter housings should not be used for more than 10 years so it might be time to upgrade now.

The COMPATIBLE OmniFilter CB3 Undersink Carbon Filter (Series B) boasts being one of the most effective carbon block cartridges available to consumers today. This under sink filter removes chlorine and odors, harmful bacteria like Giardia and Cryptosporidium, lead, and volatile organic compounds like Atrazine (a herbicide) and Lindane (a pesticide), as well as 32 other contaminant, to give you great tasting, safe drinking water right from the tap or dedicated faucet. This is the correct replacement filter for the following filtration systems only:

USM2

CBF1 Series A

CBF1 Series A

CBF3 Series B

OT32 Series B, OT32 Series E

RO2000 Series B

RO2050

This COMPATIBLE filter will also fit Ametek, Teledyne, Ace, Master Plumber, Flotec, Honeywell, GE, American Plumber and most standard size under sink water filters and Whirlpool WHCF-DB2. The CB3 also fits the Nutrition For Life Nutri-Flow HL-250 and the HL-300L
