In my house, I have two whole house water filter housings in the basement, and then a third Point-Of-Use filter housing under each sink cabinet.
Currently both basement housings contain 20-micron sediment filters, and each POU housing contains an activated carbon filter. I am satisfied with the taste of the water, but I notice particulates in my glass.
The plumbing in my house is rather old, and I was wondering if the particulates I see might be coming from some sort of buildup within the pipes themselves; rather than from the ground. (Just a thought, as I have no plumbing experience.) If that is the case, should I perhaps rearrange my filters so that the sediment filters are in each POU housing, and the carbon filter in the basement? What do you think? Also, should I get a smaller micron rating?
