Been using for years Review by John C
I have been using these filters for years and they work great at making the water taste better. They also remove a bunch of harmful items too. Our city water smells like chlorine but with this filter there is not a trace of chlorine taste. (Posted on 1/2/09)

No Problems Here Review by SeveredHead
This cartridge filters all the drinking water for a single household. It is a carbon filter used in an OmniFilter OT32 Series A undersink water filtration system. The only con is that it is becoming evermore difficult to find a merchant that carries this cartridge. (Posted on 1/4/09)

Filter Makes Water Taste Like Water Review by Slayman
Filter does its job insofar as removing bad taste of city water but installation---anything but easy because of the problem of leaking water at the top of the container. It takes multi times on and off before the leaking at the top stops AND it only works if the bottom rubber gasket is OMITTED. Defi (Posted on 3/1/09)
Filter works great for 1/2 the price Review by Randy
