CFS Compatible for CBC-10 0.5 Micron 10 x 2.5 Omnifilter CB3, GE FXUVC FXULC, Pentek CBC-10 Comparable Radial Flow Carbon Replacement Water Filters 4 PACK

They work for me.

Firstly I would like to say that the sellers response was excellent and immediate to refund my purchase although I had to pay $25 on postage to return the goods to seller. I wanted these replacement water filters to work out but you waste too much water (purging 10 or more gallons) before it becomes clear and not sure if the water is still good enough to drink. The water still tastes a little strange. After I get my refund I will pay a little more for hopefully a better result.

Item as advertised, fast shipping good price

Amazon listing states 0.5 Micron. Product packaging does not mention filtration particle size. Installed flow rate is much higher than removed .5 micron filter. This filter is installed after a whole house 20 micron filter. Water from the whole house filter in a clear glass is clear. Water from this filter is brown. Black indicates poor quality charcoal. Brown indicates something more nefarious. Water has a saline taste. I have removed the filter over health concerns.

There's no problem with the fit but who is to know if it's really filtering what it is supposed to.
