Catalytic Carbon Water Filters

[chris000]

Just wondering what kind of catalytic carbon filters (i.e. to remove chloramines) people use.
I had some filter housings already and currently use one of the below with a reduced flow (better safe than sorry, besides just opening up the faucet is even beyond the mfr.'s flow recommendation).

The reason I started using them was not because I did a ton of research on them, but the local hardware store had them.
Now, it's time for replacement again and I wonder if I should just hook up two in series to be able increase flow or look for different filters (e.g. anyone uses them too and had issues etc.).

The reaction between activated carbon and chlorine compounds is a catalyzed consumption of both the carbon and chlorine compound. That reaction is easily produced when chlorine is in the water, but is much slower when chloramines are in the water. Using activated carbon filters that contain enhanced content that is targeted at chloramines removal, is wise when you know your water is chloraminated. While those chloramines-enhanced filters are helpful, they don't improve the destruction rate that much. You still have to increase the water residence time in the filter by slowing the flow rate down substantially.

correct.
my problem is I don't know of any filter that fits those housings where the mfr. provides the peroxide number.
the datasheet for the one I have sounds too good to be true. therefore, I reduce the flow significantly to prolong bed contact time (since the idea of 'doubling' bed depth)
