Check which one you need
Much of the Bay Area’s water is treated with chloramine, and standard carbon removes very little of it. Before paying for a filter, check your disinfectant and ask whether the media is rated for chloramine.
Catalytic carbon figures come from installer-published prices, so treat them as rougher than the others.
